Methods: OCT was performed on 60 eyes of 30 healthy nondiabetic patients (control group) whom did not have any ocular disease or other systemic disease and in 60 eyes of 30 type 2 diabetic patients but no opthalmoscopic evidence of diabetic retinopathy whom did not have any ocular disease or other systemic disease. The RNFL thickneses around the optic disc in superior, inferior, nasal and temporal areas were recorded.
Results: Age, intraocular pressure and refractive error that might affect the RNFL thickness were not statistically different among the groups. Mean nasal and superior RNFL thicknesses in patients with diabetes was signifi cantly thinner than the control group (p=0.001, 0.015).
Conclusions: Early detection and treatment of DR is signifi cant in diabetic patients to reduce the risk of blindness. Superior peripapiller RNFL thickness can be useful for detecting the earlyest changes of DR in patients with diabetes..
