Dealing with rhegmatogenous retinal detachment in patients under 40 years old: a tertiary center results.

PURPOSE The risk of rhegmatogenous retinal detachment (RRD) increases with age, but some studies report a secondary peak in younger patients. Since visual recovery in RRD depends on surgical treatment and, considering the personal, social and economic burden of low vision in the working-age population, our purpose was to analyze the features and outcomes of RRD in young patients. METHODS Clinical data of patients under 40 years old submitted to surgery for first time RRD, consecutively selected between 2016 and 2019, was analyzed. Patients with less than 3 months follow-up were excluded. RESULTS Eighty-nine eyes from 89 patients were included. Mean age was 31.2 ± 7.8 years (minimum 10 years) and 56% were female gender. Most patients (63%) had high myopia. Pars plana vitrectomy (79%) alone, combined with scleral buckling (1%) or scleral buckling alone (20%) was performed. Primary anatomical success was 72%, and final anatomical success was 91%. Final visual acuity of 20/40 or better was achieved in 29% of cases, but 28% remained under 20/400. The presence of myopia (p = 0.022), localized RRD (p = 0.007) and attached macula at presentation (p < 0.001) was associated with a better final visual acuity. CONCLUSION Management of RRD in young patients must be thorough. In younger patients, anatomical outcomes may be worse than in older patients. Myopia may be recognized as a major risk factor for RRD in this age group, but also as a protective factor for retinal function after surgery.
