AbstractPurpose: To study the incidence of rhegmatogenous retinal detachment in phakic and pseudophakic myopic patients and also to study the course of posterior vitreous detachment causing retinal breaks in myopia patients.
Methods: 19 Patients presented with Rhegmatogenous retinal detachment (RRD) were examined and documented. Patients of different age groups presented with various complaints were examined. Retrospective study done, cases presented from June 2022 to December 2023 were collected from electronic data of the institute. Proper history, BCVA, Slit Lamp examination, fundus examination and documentation done. All myopia patients were examined, underwent peripheral fundus examination irrespective of degree of myopia, refractive status of patients was taken into account for screening the retina, both central and peripheral retina. Phakic as well as pseudophakic patients also underwent fundus examination if the refractive error was myopia. Posterior vitreous detachment (PVD) has major role in causing retinal pathology like retinal breaks in myopia patients during its course near sites of adhesions.
Results: Myopia is definitely a risk factor for rhegmatogenous retinal detachment, some percentage of myopia patients will escape from the retinal detachment and maintain good vision. All myopia patients have risk, but the outcome is good in mild to moderate degree of myopia compared to severe degree of myopia. Presentation of breaks is also different in different degrees of myopia. In paediatric cases, retinal detachment will remain unnoticed usually due to delayed presentation, risk of Proliferative Vitreo retinopathy (PVR) is severe, all these factors will cause irreversible blindness. RRD in myopia was commonly noted in middle age group, male gender and slightly in phakic patients more compared to pseudophakic patients.
Conclusions: Myopia is the major non traumatic cause of RRD, hence screening in myopia has important role to detect the retinal breaks as early as possible and treat to prevent the retinal detachment, which can cause severe blindness.
