No differences in anatomical success between phakic and pseudophakic eyes were found in this series. Pars plana vitrectomy was most often performed in pseudophakic eyes and had a greater probability of a worse final visual acuity than scleral buckling.

BACKGROUND:To evaluate the influence of age on the clinical characteristics of primary rhegmatogenous retinal detachments (RRD). METHODS: We conducted a retrospective review of a prospectively collected dataset. Data regarding adult patients (aged 16-100 years) who had undergone primary RRD repair, were extracted from two online databases. Baseline demographics, preoperative clinical characteristics and surgical management details were collected. [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79] ≥80) were compared using univariate analysis, with multivariate testing for interaction of age with sex, laterality and pseudophakia. RESULTS: In total, 8,133 eyes were analysed, of which the majority (59%) were in the 50-69 age-range peaking at 60, with a male predominance (64%). Myopia was significantly more frequent in patients aged <50 years. The presence of posterior vitreous detachment increased up to 50 years, then remained >95%. Foveal involvement, grade C proliferative vitreoretinopathy, total RD and greater RD extent were more common and progressively increased after 60 years, with worsening visual acuity. Isolated superior RRDs became more prevalent with age reaching a plateau in the age-range 50-69, before reducing again; conversely, isolated inferior RRDs were commoner in those <30, with a minimum in the 70-79 age-range. The incidence of fellow-eye RRD decreased linearly with age. CONCLUSIONS: Age appeared a key variable in RRD phenotype influencing a wide range of RRD characteristics. The higher incidence of myopia, PVD absent and bilateral RRD in patients <40 years and the significant phenotypical differences in the under 40 and over 50 age-groups highlight that there are several discrete forms of RRD.
