This study investigated whether endometriosis is associated with changes in the ocular surface, enrolling 25 patients with endometriosis and 25 controls who underwent complete ophthalmic examinations of the right eye. Ocular surface status was assessed using Schirmer I test, tear breakup time (TBUT), conjunctival impression cytology (CIC), and the Ocular Surface Disease Index (OSDI), and group results were compared. Patients with endometriosis had significantly lower Schirmer I and TBUT values, higher OSDI scores, and higher CIC results, with conclusions that ocular surface alterations including squamous metaplasia may be present. This paper is centrally about endometriosis — it evaluates ocular surface changes in patients with endometriosis using tear tests and impression cytology.

Abstract

ObjectiveThe aim of this study was to investigate the effect of endometriosis on the ocular surface.MethodsA total of 50 patients were included in the study and divided into two groups. Group 1 consisted of 25 patients with endometriosis. Group 2 had 25 control patients. All patients underwent complete ophthalmic examination, and the right eyes were included in the study. To evaluate the ocular surface, both groups were tested with the following: the Schirmer I test, tear breakup time (TBUT), the conjunctival impression cytology (CIC), and the Ocular Surface Disease Index (OSDI). The results were subsequently compared.ResultsThe average Schirmer I test results were 8.40 ± 2.74 mm in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average TBUT test results were 9.04 ± 3.61 s in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average OSDI results were 24.04 ± 9.29 in group 1 and were significantly higher in patients with endometriosis (P < 0.001). The average CIC results were 1.76 ± 0.88 in group 1 and were significantly higher in patients with endometriosis (P < 0.001).ConclusionsOcular surface changes, including squamous metaplasia, may be observed in the conjunctiva of patients with endometriosis.

Abstract

Objective The aim of this study was to investigate the effect of endometriosis on the ocular surface.

Methods

A total of 50 patients were included in the study and divided into two groups. Group 1 consisted of 25 patients with endometriosis. Group 2 had 25 control patients. All patients underwent complete ophthalmic examination, and the right eyes were included in the study. To evaluate the ocular surface, both groups were tested with the following: the Schirmer I test, tear breakup time (TBUT), the conjunctival impression cytology (CIC), and the Ocular Surface Disease Index (OSDI). The results were subsequently compared.

Results

The average Schirmer I test results were 8.40 ± 2.74 mm in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average TBUT test results were 9.04 ± 3.61 s in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average OSDI results were 24.04 ± 9.29 in group 1 and were significantly higher in patients with endometriosis (P < 0.001). The average CIC results were 1.76 ± 0.88 in group 1 and were significantly higher in patients with endometriosis (P < 0.001).

Conclusions

Ocular surface changes, including squamous metaplasia, may be observed in the conjunctiva of patients with endometriosis.
