A Study on Changes in Macular Thickness after Cataract Surgery in Diabetic Patients Using Optical Coherence Tomography (OCT)
Abstract: Aim To assess the macular thickness changes after cataract surgery in diabetic patients using optical coherence tomography (OCT). Materials and methods In this Prospective study, a total of 150 patients divided into three equal groups (Group 1 included non-diabetic patients, Group 2 included diabetic patients without retinopathy and group 3 included patients with diabetic retinopathy) were operated for cataract by manual Small Incision Cataract Surgery (m-SICS). Complete ophthalmological evaluation was done preoperatively. Patients were followed at day 1 post operation and at 2, 6 and 12 weeks postoperatively. At each visit a complete ophthalmic evaluation and optical coherence tomography of the macula were performed. Results There was significant increase in foveal thickness at 6 weeks in diabetics with retinopathy as compared to those without retinopathy and controls.26 % of diabetics developed macular edema as compared to 4 % in controls. Conclusion Post operative change in macular thickness and visual outcomes depends significantly on the diabetic status, duration and retinopathy levels. A positive correlation was also found between change in macular thickness and HbA1C levels in diabetic patients.
