Purpose To evaluate the efficacy of GDX to detect loss of the retinal nerve fiber layer thickness in patients with type I diabetes without retinopathy. Methods Comparative cross‐sectional study. Thirty eyes of 30 healthy subjects and 30 eyes of 30 patients with type I diabetes mellitus were studied. Ophthalmic examination of diabetic patients showed no retinopathy. One eye per patient was randomly selected for the study. The nerve fiber layer thickness was measured with polarimetry (GDx). Results The control group was formed by 9 women, 21 men, aged 18‐38 yr (mean ± SD 28.7 ± 6.01). Diabetic patients were 9 women and 21 men, aged 25.02 yr (± 8.1). Mean period from the onset of diabetes was 14.2 years (SD 5.46). None of the diabetic group had changes at the fundus examination. No differences were found between control and diabetic group. Conclusion GDx is not able to find differences in the retinal nerve fiber layer thickness in diabetic patients without retinopathy.
