Abstract: PURPOSE. To define the shape of the anterior surface of the peripapillary sclera (PPS) and evaluate its relationship with age and ocular determinants in a population-based Chinese cohort. METHODS. The optic nerve heads of 619 healthy Chinese subjects were imaged with spectral-domain optical coherence tomography. To assess the shape of the PPS/Bruch’s membrane (BM), we measured the angle between a line parallel to the nasal anterior PPS/BM boundary and one parallel to the temporal side. A negative value indicated that the PPS/BM followed an inverted v-shaped configuration (peak pointing toward the vitreous), whereas a positive value indicated that it followed a v-shaped configuration (peak pointing toward the orbital tissues). A linear regression model was used to evaluate the relationship between the PPS angle and other ocular parameters. RESULTS. The mean PPS angle was 3.68° ±6.73° and the BM angle was 9.69° ±5.05°. The PPS angle increased on average by 0.233 deg/y. A v-shaped PPS was significantly associated with age (? = 0.087, P = 0.004), peripapillary choroidal thickness (? = 0.479, P < 0.001), lamina cribrosa depth (? = 0.307, P < 0.001), and BM angle (? = 0.487, P < 0.001) after adjusting for best corrected visual acuity, central corneal thickness, and axial length. CONCLUSIONS. The anterior surface of PPS of an elderly adult population had a v-shaped configuration and was more pronounced with increasing age, thin peripapillary choroid, and a deep cup. Such a change in shape with age could have an impact on the biomechanical environment of the optic nerve head. © 2019 The Authors.
