Abstract
Macular edema (ME) is one of the most common complications following uncomplicated cataract surgery has been reported in healthy populations as well as patients with diabetes, ME is measured by an alteration in central macular thickness (CMT) using optical coherence tomography (OCT). The aim of this study is to assess correlation between diabetic profile and post phacoemulsification diabetic macular edema The patients were divided into two groups, control group involving 50 patients without diabetes and study group including 50 diabetic patients Concerning the grade of diabetic retinopathy among the studied diabetic cases 18 cases showed no diabetic retinopathy changes (36 %), 20 cases showed mild diabetic changes (20 %), 7 cases showed moderate diabetic changes (14 %) and 5 case showed severe diabetic changes (10 %). In our study the occurance of ME after cataract surgery was (28%) in diabetic group and (4%) in control group. The duration, severity, type of diabetes, HbA1c and lipid profile were risk for DME in diabetic patients after cataract surgery. In our study patients with level of HbA1C less than 7mg\dl, 3 eyes developed ME (21.4%) while patients with level ≥ 7mg\dl, 11 eyes developed ME (78.6%) with statistically significant difference between the two groups (p< 0.001). The BCVA was affected in 5 cases (35.7%) of the cases with macular edema while 11 cases (30.5%) had affection on BCVA in the cases without macular edema with no statistically significant difference between the two groups (p= 0.114). There is also no correlation between lipid profile and incidence of DME. Mean central macular thickness changes were found to be significantly affected by the severity of the diabetic retinopathy, duration of diabetes, type of diabetes and HbA1C.
