Abstract:
Objective To investigate the correlation between retinal deformation degree and retina thickness (RT) detected by optic coherent tomography (OTC) in patients with idiopathic macular epiretinal membrane (IMEM). Methods The 66 eyes (56 patients) with IMEM diagnosed by OCT were retrospectively analyzed in this study. After best corrected visual acuity (BCVA), ocular fundus and OCT examination, patients were divided into three groups (mild, medium and severe) according to retinal deformation degrees. The RT value was measured manually. Results There were significant differences in RT values between mild, moderate and severe groups:(311.95 ±51.78) μm, (447.13±41.95) μm and (560.00± 58.23) μm (P<0.05). The values of BCVA were 0.78±0.16, 0.38±0.12 and 0.27±0.14 for mild, moderate and severe groups, there were significant differences between them (P<0.05). There was no significant correlation between RT and BCVA in mild group (r=-0.352,P=0.128). There was negative correlation between RT and BCVA in medium group and serious group (r=-0.768 and-0.482,P<0.05). Conclusion The retinal deformation degree and RT are two objective indicators to assess visual performance in patients of IMEM. When RT is more than 400 μm, it can be used as objective criteria for surgical intervention.
