ABSTRACT

It was a prospective, non randomized & cross-sectional study done at Index Medical College Hospital and Research Centre, Ophthalmology OPD from DECEMBER 2016 to JUNE 2017, we had taken 160 patients who had clinically significant macular edema, out of these, 20 patients were excluded from the study: 4 patients had vitreous haemorrhage, 8 had cataract, 4 were with hard exudates and 4 patients had epiretinal membrane. Thus, the analysis was carried out on 140 patients with 140 eyes. More than one third of the patients were between 51-60 years (40.6%) followed by >60 (32.8%) and 40-50 (26.6%) years. More than half of the patients were males (58.6%). The mean BCVA was 0.54±0.40 and CFT was found to be 350.24±155.98. However, the mean CST was observed to be 387.16±154.93. There was moderate positive significant correlation of BCVA with CFT (r=0.52, p=0.0001) and CST (r=0.53, p=0.0001).
