Clinic study on macular epiretinal membrane in patients under the age of 40 years

Abstract

BackgroundTo describe the risk factors and clinical characteristics of macular epiretinal membrane (MEM) disease in patients up to the age of 40 years and to evaluate the therapeutic effect of IVTA on MEM.MethodsClinical records were reviewed and the etiology of each case and the age distribution data were collected in this retrospective, cohort study. The clinical characteristics of MEM and the factors affecting VA were analyzed. Additionally, we contrasted the effects of MEM peeling with and without intravitreal triamcinolone acetonide on visual acuity (VA) and central foveal thickness (CFT).ResultsIn young patients, the incidence of partial posterior vitreous detachment (P-PVD) was considerably higher in IMEM than SMEM (P = 0.007). Furthermore, patients with stage 3 MEM had lower BCVA values than patients with stage 4 MEM (P < 0.001). Patients who live in urban had lower BCVA values than patients in rural (P < 0.001). Patients with IS/OS integrity had lower BCVA values than patients without IS/OS integrity (P < 0.001). The BCVA values in patients with IMEM were significantly lower than those of patients with SMEM (P < 0.001). BCVA was associated most commonly with etiology (P = 0.001), followed by region (P = 0.002). All patients had a decrease in logMAR Vas and CFT, but the combination of intraoperative IVTA resulted in a more significant decrease in logMAR Vas (P = 0.007) and CFT (P = 0.046).ConclusionIn young patients, the incidence of P-PVD was significantly higher in IMEM cases than in SMEM cases. The region, MEM stage, IS/OS integrity, and etiology influenced VA. Etiology was associated most commonly with BCVA. In individuals under 40, the combination of intraoperative IVTA resulted in a more significant decrease in logMAR Vas and CFT.
