OCT
All the patients will undergo OCT imaging using NIDEK RS-330 Retina scan duo 2 (SD-OCT)(CO-LTD made in Japan 2017) with scan speed 70.000 axial scans per second and wavelength of 880 nm. A three-dimensional scan protocol will be used for macular measurements. Macular scans will be performed with axial scanning protocols covering a 9 × 9 mm area centered on the fovea. OCT images will be evaluated by a trained ophthalmologist for the following: \- Stage of ERM will be classified by Govetto et al system into stage 1,2,3 or 4. Stage 1: ERMs were mild and thin. Foveal depression is present. Stage 2: ERMs with a widening of the outer nuclear layer and loss of the foveal depression. Stage 3: ERMs with continuous ectopic inner foveal layers crossing the entire foveal area. Stage 4: ERMs were thick with continuous ectopic inner foveal layers and disrupted retinal layers. \- central macular thickness CMT
