Assessment of Macular and Choroidal Thickness in Diabetic Patients in Relation to Glycemic Control

Background: Retinopathy, or diabetic eye disease, is a condition in which damage to the retina develops as a result of diabetes. One potential consequence of DR is blindness. Aim and objectives: The purpose of assessing diabetes patients' glucose control in relation to choroidal and macular thickness is to. Subjects and methods: Patients with diabetes who visited the Retina clinic at Al-Azhar University Hospitals between January 2024 and October 2024 were the subjects of this non-cohort, cross-sectional study. Patients were subdivided according to HbA1c levels into 3 subgroups: group-A HbA1c 7 and below, group-B 7-8% and group-C HbA1c above 8%. Each group was examined for SF CT and CMT by OCT. Results: The groups varied significantly in terms of sub-foveal choroidal thickness (μm). Group A had the highest mean value (289.47±49.7), followed by group B (219.6±30.9), and group C had the lowest value (192.46±20.6). Based on central macular thickness (CMT), there is an extremely significant difference between the groups. Group-C had the highest mean value (283.98±50.96), followed by group-B (250.99±41.3), and group-A had the lowest (216.8±29.6). Conclusion: From the results of this study we concluded that, there were positive correlation between HbA1c levels with CMT and negative with SF CT.
