BACKGROUND: To examine the impact of peripapillary atrophy (PPA) on retinal nerve fibre layer (RNFL), ganglion cell-inner plexiform layer (GCL-IPL), and Bruch's membrane opening-minimum rim width (BMO-MRW) in non-glaucomatous myopic eyes.
METHODS: Patients with myopic refractive errors greater than -4.00 dioptres and with normal intraocular pressure (10-21 mmHg) were included in the study. Eyes without PPA were included in group 1, and those with PPA in group 2. RNFL (3.5, 4.1, 4.7 mm) and BMO-MRW were measured with Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany); GCL-IPL with Cirrus HD-OCT 5000 (Carl Zeiss Meditec, Dublin, CA, USA).
RESULTS: There were 50 eyes in group 1 and 77 eyes in group 2. Mean age, refractive error, axial length, disc area, rim area, cup-to-disc ratio, mean RNFL and GCL-IPL (mean and minimum) were similar in both groups (p > 0.05 for all). Mean nasal RNFL thickness measured with Cirrus HD-OCT and mean nasal RNFL thicknesses at 3.5 mm and 4.1 mm measured with Spectralis OCT were significantly lower in group 2 (p < 0.05 for all). Nasal RNFL thickness at 4.7 mm and RNFL thicknesses in the other regions at different diameters (3.5 mm, 4.1 mm and 4.7 mm) and BMO-MRW in all regions were similar in both groups (p > 0.05 for all).
DISCUSSION: RNFL thickness at 4.7 mm, BMO-MRW, and GCL-IPL did not significantly differ with PPA. These stable measurements may assist in diagnosing and monitoring glaucoma in myopic eyes with PPA.
