Purpose
The objective of this study was to assess the effect of diabetic retinopathy (DR) on the retinal nerve fiber layer (RNFL) thickness.
Patients and methods
This study included 30 diabetic patients having nonproliferative diabetic retinopathy (NPDR) without macular edema, 20 diabetic patients without DR, and 20 healthy nondiabetic age-matched individuals as a control group. In each patient one eye was included. Patients were evaluated for RNFL thickness by Heidelberg Spectralis optical coherence tomography.
Results
The global (G), the superior, and the temporal RNFL thickness in the diabetic patients without DR was significantly less than that of the control group and that of the patients with NPDR. However, there was no statistically significant difference between the patients with NPDR and the control group. It was noted that there was no statistically significant difference in the RNFL thickness of the inferior and nasal quadrants between the three studied groups.
Conclusion
Early retinal neurodegeneration can occur before retinal microvascular diabetic changes can be observed. |
