2M.D. Professor, Sakarya University Training and Research Hospital, Eye Clinic, Sakarya/TURKEY Purpose: To investigate the frequency of serous retinal detachment (SRD) in diabetic macular edema (DME) and relationship with serum glycosylated hemoglobin (HbA1c) levels.
Material and Methods: 124 eyes of 124 patients with DME were investigated retrospectively. Cases with only DME was defined as group 1 and cases with DME and SRD was defined as group 2 due to optic coherence tomography (OCT) findings. Age, duration of diabetes, hypertension, HbA1c levels, best corrected visual acuity (BCVA) and central macular thickness (CMT) were compared between the groups.
Results: The mean age of 66 male (%53) and 58 female (%47) patients was 63.4±7.5 years. SRD was present in 57 of 124 patients (45.9%). Age, duration of diabetes and presence of hypertension were statistically similar between the groups. Mean HbA1c level was 8.6±0.9 (6.1- 11.3) mg/dl in group 1 and 9.8±1.32 (6.9-14.2) mg/dl in group 2 and the difference was statistically significant (p<0.001). Mean BCVA was 0.54±0.18 LogMAR (1-0.30) in group 1 and 0.64±0.23 LogMAR (1.30-0.40) in group 2 and the difference was statistically significant (p<0.001). Mean CMT was 398±72.4 µm in group 1 and 434.6±66.8 µm in group 2 and the difference was statistically significant (p<0.001).
Conclusion: In our study, SRD was found to be common in patients with DME and higher HbA1c levels seemed to be related with presence of SRD.
