Materials and Methods This study evaluated a total of 240 eyes from 120 diagnosed keratoconus patients according to four different age groups (0–12, 13–18, 19–25, ≥ 26 years). Pentacam corneal topography and pachymetry were used in the diagnostic processes, and disease staging was performed according to the Amsler-Krumeich classification. Additionally, comprehensive corneal parameters were recorded; anterior and posterior surface measurements (K1, K2, KM, and astigmatism), corneal thickness, volume, anterior chamber depth, and Belin-Ambrosio enhanced ectasia parameters. Results Gender distribution, disease stage, and visual acuity were similar across age groups. The 0–12 age group showed higher central corneal thickness compared to the 13–18 and 19–25 age groups, while anterior and posterior surface curvature measurements (K1, K2, and KM) exhibited significant differences between pediatric and adult groups. In females, keratoconus stages, anterior surface K1, K2, KM, posterior surface K1, K2, KM, D, and Q-VAL values were found to be significantly higher (p < 0.05) than in males, while the IT value was significantly lower (p < 0.05). Conclusion Our findings reveal that corneal thickness, curvature, and progression indices show a significant increase in keratoconus patients, especially in the 0–12 age group, and emphasize the importance of early diagnosis and age-appropriate treatment strategies. Age distribution Corneal topography Keratoconus Pediatric keratoconus Pentacam Progression indices Introduction Keratoconus is a progressive, bilateral, and asymmetric corneal ectasia characterized by stromal thinning and protrusion, leading to irregular astigmatism and visual impairment ( 1 ). Recent epidemiological studies have reported varying prevalence rates across different populations, with estimates ranging from 0.05–2.5% ( 2 ). The advent of corneal tomography, particularly Scheimpflug imaging technology, has revolutionized the detection and monitoring of keratoconus progression ( 3 ). These advanced imaging modalities permit comprehensive analysis of anterior and posterior corneal surfaces, enabling earlier diagnosis and more precise disease staging ( 4 ). Understanding the natural progression patterns of keratoconus across different age groups is crucially important for clinical decision-making and treatment planning. Meta-analyses have demonstrated that progression rates vary significantly with age, with younger patients exhibiting more rapid progression and requiring earlier intervention ( 5 ). The disease typically manifests during puberty and early adulthood, with recent studies indicating that pediatric cases frequently exhibit more aggressive progression compared to adult-onset cases ( 6 ). Research has shown that approximately 88% of affected eyes exhibit progression within the first few years after diagnosis, the rate of progression being particularly rapid in younger patients under the age of 18 ( 7 ). This age-related variation in disease progression has significant implications for both prognostic counseling and therapeutic intervention timing. The impact of keratoconus on visual function varies significantly across different age groups, younger patients frequently experiencing more severe visual impairment due to faster progression rates ( 8 ). Pediatric patients show significantly more rapid progression in refractive errors, including spheres and cylinders, spherical equivalence, steep K, and flat K during follow-up ( 9 ). This accelerated progression in younger populations has been attributed to various factors, including hormonal changes during puberty, increased oxidative stress, and biomechanical factors specific to the developing cornea ( 10 ). This study investigated the distribution and characteristics of keratoconus across different age groups in a tertiary eye center, with particular comparison between pediatric and adult populations. By analyzing comprehensive corneal parameters using Pentacam HR technology, we set out to elucidate potential age-related patterns in disease presentation and severity, which may potentially inform clinical decision-making and therapeutic strategies. Materials and Methods This cross-sectional study involved patients diagnosed with primary keratoconus at a tertiary eye clinic in Türkiye from January 2020 to December 2024. The study population was divided into four groups: two pediatric (age 0–12 and 13–18 years) and two adult (age 19–25 years and 26 + years). Two hundred forty eyes of 120 patients with bilateral keratoconus were included in the study. The study was approved by the XXX University clinical research ethics committee on 13 January, 2025, under protocol number XXX/25.01.47. Due to its retrospective nature, the informed consent requirement was waived. The research was conducted in full compliance with the ethical principles set out in the Declaration of Helsinki. Keratoconus was diagnosed through the evaluation of characteristic corneal protrusion patterns detected via corneal topography analyses (Pentacam, OCULUS Optikgerate GmbH, Wetzlar, Germany), in conjunction with pachymetry applied to assess corneal thinning, refractive errors such as myopia and irregular astigmatism, and slit-lamp biomicroscopic findings including Fleischer ring, Vogt’s striae, Munson’s sign, and Rizzuti’s sign. Bilateral cases were stratified into four stages according Amsler-Krumeich’s classification, based on astigmatism, corneal power, corneal transparency, and corneal thickness. The following parameters were recorded based on Pentacam images: for the anterior surface, the measurements included K1​, K2​, KMax, and astigmatism, while K1, K2​, KMax​, and astigmatism were recorded for the posterior surface. Corneal volume and anterior chamber depth were also evaluated. Belin-Ambrósio enhanced ectasia parameters were assessed, including the progression index and values such as minimum value (min), maximum value (max), average (avg), Ambrósio relational thickness (ART), Belin-Ambrósio deviation value (D), quality value (Q-VAL), and index of thickness (IT). A retrospective analysis of Pentacam-derived topographic and tomographic imaging was conducted for both the pediatric and adult cohorts. Scans meeting stringent quality parameters were included for evaluation, while those exhibiting suboptimal or inadequate acquisition characteristics were excluded from the final analysis. All participants underwent comprehensive ophthalmic examinations including determination of uncorrected and best corrected visual acuity, slit-lamp biomicroscopy, intraocular pressure measurement, and dilated fundus examination. Exclusion criteria were a previous history of ocular surgery, a history of contact lens use, extensive corneal scarring, acute hydrops, or an obvious defect in the Descemet membrane, and previous receipt of collagen crosslinking. Statistical Analysis The study data were expressed as mean, standard deviation, median, minimum, maximum, frequency, and ratio values. The distribution of variables was evaluated using the Kolmogorov-Smirnov and Shapiro-Wilk tests. The Kruskal-Wallis test was applied in the analysis of non-normally distributed quantitative independent data, and the chi-square test for qualitative independent data. The analyses were conducted on SPSS version 28.0 software. Results No significant difference (p > 0.05) in gender distribution was observed among the 0–12, 13–18, 19–25, and ≥ 26 age groups. No significant differences were also determined in disease stage or vision values among keratoconus patients in the different age groups (0–12, 13–18, 19–25, and ≥ 26) (p > 0.05). However, CCT was significantly higher in the 0–12 age group (p < 0.05) than in the 13–18 and 19–25 age groups. Anterior surface K1 values were significantly higher in the 13–18 age group (p < 0.05) than in the 19–25 and ≥ 26 age groups. Anterior surface K1 values were significantly higher in the 19–25 age group (p < 0.05) than in the 0–12 age group. Anterior surface K2 values were significantly higher in the 19–25 age group (p < 0.05) than in the ≥ 26 age group. Anterior surface KM values were significantly higher in the 13–18 age group (p < 0.05) than in the 19–25 and ≥ 26 age groups. Anterior surface KM values were significantly higher in the 19–25 age group (p < 0.05) than in the 0–12 age group Posterior surface K1 values were significantly higher in the 19–25 age group (p < 0.05) than in the 0–12 and ≥ 26 age groups. Posterior surface K2 values were also significantly higher in the 19–25 age group (p < 0.05) than in the 0–12 age group. Finally, posterior surface KM values were significantly higher in the 19–25 age group (p < 0.05) than in the 0–12 and ≥ 26 age groups (Table 2 ).

Our study revealed significant gender differences in keratoconus presentation. Males exhibited predominantly Stage I disease (83.3%) compared to females (54.3%, p = 0.001), who showed more diverse staging (Stage II: 28.6%, Stage III: 7.1%, Stage IV: 10.0%). Males demonstrated significantly lower anterior and posterior keratometry values (p < 0.001), suggesting less pronounced corneal steepening. Females presented with higher D values (8.3 ± 8.6 vs 5.4 ± 3.7, p = 0.020) and Q-VAL (0.79 ± 0.44 vs 0.62 ± 0.36, p = 0.010), while males showed elevated IT values (1.06 ± 0.82 vs 0.82 ± 0.47, p = 0.035). No significant gender differences were observed in BCVA, IOP, CCT, corneal volume, or anterior chamber depth (Table 4 ).

The findings indicate that keratoconus tends to exhibit a more severe progression in younger age groups. This further emphasizes the importance of early diagnosis and intervention strategies. Data consistent with those of previous studies suggest that the pathophysiology of the disease includes age- and gender-related differences, while also highlighting the need for multidisciplinary approaches. The results thus confirm the need to consider demographic parameters in the clinical management of keratoconus. The fact that the biomechanical structure of the cornea is not yet fully established in the younger age group, together with differences in the elasticity of eye tissue, combined with genetic factors, support the possibility that the disease may progress more aggressively. However, factors such as gene-environment interactions should be carefully considered in the causal interpretation of results. It should also be remembered that instrumental variable analyses yield causal effects only under specific assumptions. Yang et al. demonstrated that the manifestation of pediatric keratoconus varies across different age groups. Those authors reported that patients under 14 years exhibit more advanced and aggressive stages of the disease, whereas those in the 14–16 age bracket predominantly present with moderate stage findings. In contrast, patients aged 16–18 years tend to exhibit lower stage disease, suggesting a slower progression in this group ( 11 ). Similarly, Rocha de Lossada et al. observed that patients younger than 14 exhibit a more aggressive keratoconus course, characterized by a reduced corneal thickness, a high keratoconus index, and pronounced aberrations, while those aged 14 and older exhibit a more gradual disease progression along with increasingly distinctive gender differences during adolescence ( 12 ). Naderan et al. reported that pediatric keratoconus cases experienced a significantly more aggressive disease course compared to adult patients, as evidenced by marked differences in parameters such as mean anterior and posterior measurements, flat and steep meridian values, maximum elevation, and anterior chamber depth ( 13 ). Moreover, Moshirfar et al. reported that keratoconus is both more prevalent and more progressive in children than in adults, underscoring the importance of incorporating keratoconus screening into school health programs ( 14 ). Keratoconus progression indices serve to monitor how rapidly changes occur in the corneal morphology and biomechanics of patients and provide information about the future course of the disease. Regularly monitored progression index parameters are used to observe changes over time ( 15 ). Studies emphasize that Belin-Ambrósio parameters play a significant role in the early detection of ectatic changes, particularly by integrating multiple corneal metrics. This is especially important in clinical settings, where prompt intervention can help manage the progression of keratoconus ( 16 ). In the present study, despite CCT values being significantly higher in the 0–12 age group compared to other age groups, the progression indices, specifically the minimum and maximum values, ART, and IT parameters, were distinctly higher in this group. This finding, as also reported in previous studies, confirms that early-onset keratoconus is characterized by rapid, localized changes in corneal structure (11–15). In particular, the significantly higher IT value relative to all other age groups suggests that changes in corneal thickness parameters occur more rapidly in this age group. The ART progression index was higher in the 13–18 age group than in the 19–25 age group, while posterior surface K1 and posterior surface K2 values were significantly higher in the 19–25 age group compared to the 0–12 age group. These findings indicate that keratoconus in young adults progresses with more pronounced changes, particularly in the posterior corneal surface. The differences between these age groups reveal that keratoconus exhibits varied clinical characteristics and progression patterns depending on the age of the patient. While early-onset keratoconus exhibits a more aggressive course, the disease progresses by affecting different corneal parameters during adolescence and young adulthood. Additionally, posterior corneal parameters become more prominent in the ≥ 26 age group. The individualization of management strategies is therefore important due to more stable or differently progressing patterns in this age group. The majority of studies have shown that males present with keratoconus at a younger age and with more aggressive clinical findings, while others have suggested that gender does not have a significantly effect on risk factors or prognosis. However, some studies have reported more pronounced correlations in females, particularly at tomographic and aberrometric analyses ( 11 , 12 , 17 , 18 ). Studies’ demographic structures, age distributions, ethnic origins, and geographical regions can all create differences in gender-related clinical presentations. In our study, the significantly higher keratoconus progression index observed in females may reflect the higher prevalence of advanced disease stages in women. This suggests that keratoconus may follow different progression patterns in males and females, with men tending to seek evaluation at an earlier stage of the disease. Limitation The data used in this study were obtained solely from a tertiary eye center, which limits the generalizability of the results to populations in different geographical regions and with varying levels of healthcare. Additionally, the small number of patients in some age and gender subgroups may have reduced the statistical power of the analyses and affected the reliability of the findings. Moreover, the limited long-term follow-up data make a full evaluation of the progression of keratoconus and age-related changes problematic. Conclusion Overall, the results of this study support the idea that the course of keratoconus at initial diagnosis differs according to age groups, the disease potentially progressing more aggressively in younger patients. The findings also provide a valuable reference for evaluating the effectiveness of clinical interventions and developing treatment strategies, while also emphasizing the importance of early intervention in public health policies. Notably, although CCT values were significantly higher in the 0–12 pediatric age group compared to the adult group, several key progression indices including minimum, maximum, ART, and IT parameters were markedly elevated relative to older age groups. From that perspective, we think that the results of this study will make a significant contribution to both clinical practice and policy development. Further multicenter, prospective studies with larger sample sizes are therefore needed for a more comprehensive evaluation of the natural course of keratoconus and its age-related differences.

Recent epidemiological studies have reported varying prevalence rates across different populations, with estimates ranging from 0.05\u0026ndash;2.5% (\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThe advent of corneal tomography, particularly Scheimpflug imaging technology, has revolutionized the detection and monitoring of keratoconus progression (\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e). These advanced imaging modalities permit comprehensive analysis of anterior and posterior corneal surfaces, enabling earlier diagnosis and more precise disease staging (\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eUnderstanding the natural progression patterns of keratoconus across different age groups is crucially important for clinical decision-making and treatment planning. Meta-analyses have demonstrated that progression rates vary significantly with age, with younger patients exhibiting more rapid progression and requiring earlier intervention (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e). The disease typically manifests during puberty and early adulthood, with recent studies indicating that pediatric cases frequently exhibit more aggressive progression compared to adult-onset cases (\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e). Research has shown that approximately 88% of affected eyes exhibit progression within the first few years after diagnosis, the rate of progression being particularly rapid in younger patients under the age of 18 (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e). This age-related variation in disease progression has significant implications for both prognostic counseling and therapeutic intervention timing.\u003c/p\u003e \u003cp\u003eThe impact of keratoconus on visual function varies significantly across different age groups, younger patients frequently experiencing more severe visual impairment due to faster progression rates (\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e). Pediatric patients show significantly more rapid progression in refractive errors, including spheres and cylinders, spherical equivalence, steep K, and flat K during follow-up (\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e). This accelerated progression in younger populations has been attributed to various factors, including hormonal changes during puberty, increased oxidative stress, and biomechanical factors specific to the developing cornea (\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThis study investigated the distribution and characteristics of keratoconus across different age groups in a tertiary eye center, with particular comparison between pediatric and adult populations.

examination of the distribution of keratoconus in terms of age and gender groups, and of the relationship between the progressive course of the disease and demographic factors. The findings indicate that keratoconus tends to exhibit a more severe progression in younger age groups. This further emphasizes the importance of early diagnosis and intervention strategies. Data consistent with those of previous studies suggest that the pathophysiology of the disease includes age- and gender-related differences, while also highlighting the need for multidisciplinary approaches. The results thus confirm the need to consider demographic parameters in the clinical management of keratoconus.\u003c/p\u003e \u003cp\u003eThe fact that the biomechanical structure of the cornea is not yet fully established in the younger age group, together with differences in the elasticity of eye tissue, combined with genetic factors, support the possibility that the disease may progress more aggressively. However, factors such as gene-environment interactions should be carefully considered in the causal interpretation of results. It should also be remembered that instrumental variable analyses yield causal effects only under specific assumptions.\u003c/p\u003e \u003cp\u003eYang et al. demonstrated that the manifestation of pediatric keratoconus varies across different age groups. Those authors reported that patients under 14 years exhibit more advanced and aggressive stages of the disease, whereas those in the 14\u0026ndash;16 age bracket predominantly present with moderate stage findings. In contrast, patients aged 16\u0026ndash;18 years tend to exhibit lower stage disease, suggesting a slower progression in this group (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e). Similarly, Rocha de Lossada et al. observed that patients younger than 14 exhibit a more aggressive keratoconus course, characterized by a reduced corneal thickness, a high keratoconus index, and pronounced aberrations, while those aged 14 and older exhibit a more gradual disease progression along with increasingly distinctive gender differences during adolescence (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e). Naderan et al. reported that pediatric keratoconus cases experienced a significantly more aggressive disease course compared to adult patients, as evidenced by marked differences in parameters such as mean anterior and posterior measurements, flat and steep meridian values, maximum elevation, and anterior chamber depth (\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e). Moreover, Moshirfar et al. reported that keratoconus is both more prevalent and more progressive in children than in adults, underscoring the importance of incorporating keratoconus screening into school health programs (\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eKeratoconus progression indices serve to monitor how rapidly changes occur in the corneal morphology and biomechanics of patients and provide information about the future course of the disease. Regularly monitored progression index parameters are used to observe changes over time (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e). Studies emphasize that Belin-Ambr\u0026oacute;sio parameters play a significant role in the early detection of ectatic changes, particularly by integrating multiple corneal metrics. This is especially important in clinical settings, where prompt intervention can help manage the progression of keratoconus (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eIn the present study, despite CCT values being significantly higher in the 0\u0026ndash;12 age group compared to other age groups, the progression indices, specifically the minimum and maximum values, ART, and IT parameters, were distinctly higher in this group. This finding, as also reported in previous studies, confirms that early-onset keratoconus is characterized by rapid, localized changes in corneal structure (11\u0026ndash;15). In particular, the significantly higher IT value relative to all other age groups suggests that changes in corneal thickness parameters occur more rapidly in this age group.\u003c/p\u003e \u003cp\u003eThe ART progression index was higher in the 13\u0026ndash;18 age group than in the 19\u0026ndash;25 age group, while posterior surface K1 and posterior surface K2 values were significantly higher in the 19\u0026ndash;25 age group compared to the 0\u0026ndash;12 age group. These findings indicate that keratoconus in young adults progresses with more pronounced changes, particularly in the posterior corneal surface. The differences between these age groups reveal that keratoconus exhibits varied clinical characteristics and progression patterns depending on the age of the patient. While early-onset keratoconus exhibits a more aggressive course, the disease progresses by affecting different corneal parameters during adolescence and young adulthood. Additionally, posterior corneal parameters become more prominent in the \u0026ge;\u0026thinsp;26 age group. The individualization of management strategies is therefore important due to more stable or differently progressing patterns in this age group.\u003c/p\u003e \u003cp\u003eThe majority of studies have shown that males present with keratoconus at a younger age and with more aggressive clinical findings, while others have suggested that gender does not have a significantly effect on risk factors or prognosis. However, some studies have reported more pronounced correlations in females, particularly at tomographic and aberrometric analyses (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). Studies\u0026rsquo; demographic structures, age distributions, ethnic origins, and geographical regions can all create differences in gender-related clinical presentations. In our study, the significantly higher keratoconus progression index observed in females may reflect the higher prevalence of advanced disease stages in women. This suggests that keratoconus may follow different progression patterns in males and females, with men tending to seek evaluation at an earlier stage of the disease.\u003c/p\u003e"},{"header":"Limitation","content":"\u003cp\u003eThe data used in this study were obtained solely from a tertiary eye center, which limits the generalizability of the results to populations in different geographical regions and with varying levels of healthcare. Additionally, the small number of patients in some age and gender subgroups may have reduced the statistical power of the analyses and affected the reliability of the findings. Moreover, the limited long-term follow-up data make a full evaluation of the progression of keratoconus and age-related changes problematic.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003e Overall, the results of this study support the idea that the course of keratoconus at initial diagnosis differs according to age groups, the disease potentially progressing more aggressively in younger patients. The findings also provide a valuable reference for evaluating the effectiveness of clinical interventions and developing treatment strategies, while also emphasizing the importance of early intervention in public health policies. Notably, although CCT values were significantly higher in the 0\u0026ndash;12 pediatric age group compared to the adult group, several key progression indices including minimum, maximum, ART, and IT parameters were markedly elevated relative to older age groups. From that perspective, we think that the results of this study will make a significant contribution to both clinical practice and policy development. Further multicenter, prospective studies with larger sample sizes are therefore needed for a more comprehensive evaluation of the natural course of keratoconus and its age-related differences.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e \u003ch2\u003eEthical Approval:\u003c/h2\u003e \u003cp\u003e This study was conducted in accordance with the principles of the Declaration of Helsinki.
