Abstract:
PURPOSE: To investigate the relation between retinal nerve fiber layer (RNFL) defect and grade of diabetic retinopathy in diabetic patients with normal intraocular pressure (IOP). METHODS: The medical records of 260 patients with nonproliferative diabetic retinopathy (NPDR) were reviewed retrospectively. Patients with diseases and congenital anomaly were excluded. According to the results of visual acuity, IOP, slit lamp examination and fluorescein angiography, patients were classified into 3 groups, mild, moderate, severe NPDR. RNFL photography was also performed in all patients. RESULTS: Average age of 260 patients (520 eyes) was 60 year-old, and average IOP was 16.8mmHg. 372 eyes were mild NPDR, 76 were moderate, and 72 were severe. 136 eyes (25.2%) had RNFL defects including wedge-shaped defect (107 eyes; 78.7%) and diffuse atrophy (29 eyes; 21.3%). RNFL defects were observed in patients with mild NPDR (84 eyes), moderate (24 eyes), and severe (28 eyes) and there were a significant correlation between RNFL defect and severity of diabetic retinopathy (p=0.008). CONCLUSIONS: Careful examination and continuous follow-up are necessary in patients with diabetic retinopathy because RNFL defect was common in diabetic patients and increased according to the degree of diabetic retinopathy.
