Parapapillary Gamma Zone and Axial Elongation-Associated Optic Disc Rotation: The Beijing Eye Study.
PURPOSE The parapapillary gamma zone has been defined as the parapapillary region without Bruch's membrane. We examined which morphologic parameters are associated with the presence and size of the parapapillary gamma zone. METHODS Using fundus photographs and spectral-domain optical coherence tomographic images of the optic nerve head in the population-based Beijing Eye Study, we determined ...
متن کاملOptic Disc - Fovea Distance, Axial Length and Parapapillary Zones. The Beijing Eye Study 2011
PURPOSE To measure the distance between the optic disc center and the fovea (DFD) and to assess its associations. METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals aged 50+ years. The DFD was measured on fundus photographs. RESULTS Readable fundus photographs were available for 2836 (81.8%) individuals. Mean DFD was 4.76 ± 0.34 mm (median: 4.74 mm...
متن کاملHorizontal and vertical optic disc rotation. The Beijing Eye Study
PURPOSE To measure the optic disc rotation around the vertical and horizontal disc axis and to evaluate associations with general and ocular parameters. DESIGN Population-based study. METHODS In the Beijing Eye Study, 3468 participants (mean age:64.6±9.8 years; range:50-93 years) underwent an ophthalmological examination which included spectral-domain optical coherence tomography (OCT) with...
متن کاملPeripapillary Suprachoroidal Cavitation, Parapapillary Gamma Zone and Optic Disc Rotation Due to the Biomechanics of the Optic Nerve Dura Mater.
We thank Jonas and colleagues1 for their interest in our recent paper.2 We agree with the assertion from Jonas and colleagues1 that the biomechanics of the optic nerve dura mater, especially during eye movements, may have strong implications for various structural changes observed in highly myopic eyes. For instance, our models may be able to provide explanations about the optic disc rotation a...
متن کاملParapapillary Gamma Zone and Progression of Myopia in School Children: The Beijing Children Eye Study.
Purpose To assess the development and enlargement of the parapapillary gamma zone in school children. Methods This school-based prospective longitudinal study included Chinese children attending grade 1 in 2011 and returning for yearly follow-up examinations until 2016. These examinations consisted of a comprehensive ocular examination with biometry and color fundus photographs. The parents u...
