The Characteristics of Pseudophakic Retinal Detachment and Risk Factors of Recurrence in the North of Spain

Purpose: The present study was designed to gain knowledge about the prognostic factors and evolution of pseudophakic retinal detachment (PRD). To analyse the main characteristics of PRD, such as the mean time to retinal detachment following cataract surgery, as well as the clinical factors associated with the risk of recurrence, and with worse anatomical and functional outcomes. Methods: Retrospective study of 330 patients with PRD between 2012-2020.All patients are pseudophakic ,were referred for retinal detachment surgery at the Donostia University Hospital (Terciary Hospital, Spain). Results: The mean age of patients was 63.06 ± 10.8 at the time of phacoemulsification and 49.09% of them had moderate myopia ( axial length (AL) (23.5 26.5 mm). In our serie, macular detachment was evident in 69.09% of patients. The mean time that elapsed between phacoemulsification and RD surgery was 4.04 ± 4.17 years, being reduced by half in the event of surgical complications (2.24 ± 2.65). The rate of recurrence of RD was 28.79%. The anatomical results in terms of retinal reapplication have been better by combining vitrectomy with scleral buckle (83.1% vs 70.5%). The variables associated with a higher risk of recurrence were male gender (Hazard ratio -HR= 1.75), macular detachment (HR= 2.00) and the presence of proliferative vitreoretinopathy (PVR) (HR= 3.21) Conclusions :PRD usually occurs within 4 years of phacoemulsification, although it may occur significantly earlier in the event of surgical complications. The involvement of the macula, PVR, and male gender are all associated with a higher risk of PRD recurrence.
