Abstract

To assess whether macular Bruch´s membrane gets lengthened in axial myopia.Using the enhanced depth imaging mode of spectral-domain optical coherence tomography and examining a subgroup of participants of the population-based cross-sectional Beijing Eye Study, we measured the length of Bruch´s membrane ("MacBMLength") from the fovea to the temporal edge of parapapillary gamma zone, and the distance between the fovea and the temporal optic disc border. Parapapillary gamma zone was defined as the parapapillary region without Bruch's membrane. We additionally measured ocular biometric parameters and assessed non-ophthalmologic variables.Measurements of MacBMLength were performed on 322 individuals. MacBMLength (mean: 3.99 ± 0.33 mm; range: 3.17-4.93 mm) was not significantly associated with any systemic parameter or ocular biometric parameter. Gamma zone width (mean: 0.18 ± 0.30 mm; range: 0.00-2.61 mm) was associated (multivariate analysis; correlation coefficient r:0.80) with longer axial length (P
