Patients who fulfilled the inclusion criteria were interviewed regarding the duration of diabetes mellitus and treatment history. A complete ophthalmologic examination including Central Macular Thickness (CMT) and were performed to all patients. Results: A total of 260 eyes from 130 patients (87 males, 43 females; mean age 56.88±8.26 years) were included in this study. The mean duration of DM was 8.87±2.34 years (range, 1-25 years). In the present study, CMT in right eye ranged from 189–751 μm with mean value of 260.41±101.66. CMT in left eye ranged from 180–561 μm with mean value of 255.69±88.89. Among 130 subjects, clinically significant macular edema (CSME) was present in 30% (n=39). CMT was found to be significantly raised in CSME group with a mean of 355.02±126.68 μm compared to no CSME group with a mean CMT value of 216.48±19.72 μm (p= <0.001). Conclusion: Present study concluded that Increased Central Macular Thickness (CMT) was significantly correlated with clinically significant macular edema (CSME) among Patients of Type 2 Diabetes Mellitus present at Ophthalmology OPD.
