The mean age of 11 patients was 59.72±9.94 years. The mean BCVA of the study was 0.43±0.31 and mean BCVA of the control group was 0.86±0.23 in decimal (P=0.01). The mean IOP of the study group 15.72±1.55 mmHg and the mean IOP of the control group was 16.09±2.17 mmHg (P=0.656). Only one eye of the study group was phakic (%9.09). This eye had SBS procedure. Two eyes of the control group were pseudophakic (%18.18). Three, 5 and 3 eyes in the study group had PPV, SBS and PPV+SBS procedures, respectively. Only one eye had combination of PPV and SBS was with silicone. This eye had a 19-month duration following the surgery. The mean time duration of the study group was 27.00±26.43 months (2-84 months). The OCTA measurements of the eyes with vitreoretinal surgery and the fellow eyes are shown on table 1.
