Myopic maculopathy imaged by optical coherence tomography: the beijing eye study.

摘要: Purpose To examine the features of myopia-related optical coherence tomography (OCT) findings in a population-based setting. Design Population-based study. Participants The Beijing Eye Study 2011 included 3468 subjects with an age 50 years or more. Methods participants underwent detailed ophthalmic examination including OCT enhanced depth imaging macula. Main Outcome Measures Optical macula highly myopic eyes defined by refractive error of −6 diopters less axial length 26.5 mm Results Readable images were available for 6530 (94.5%) 3278 participants. most common change was maculoschisis (0.8±0.1%), followed incomplete posterior vitreous detachment (0.7±0.1%), disruption photoreceptor inner segment/outer segment interface (0.6±0.1%), epiretinal membranes macular defects Bruch's membrane (0.3±0.1%), clumping retinal pigment epithelium (0.2±0.1%), vitreofoveal adhesion and holes 2 (0.1±0.1%). Prevalence any maculopathy per eye 112 6530, 1.71±0.16% (95% confidence interval [CI], 1.40–2.03). After adjustment longer ( P ≥0.05), biochemical blood ocular parameters. Best-corrected visual acuity associated significantly absence Conclusions Based on examination, maculoschisis, detachment, interface, membranes, membrane, epithelium, adhesion, holes. important changes negative effect best-corrected membranes.
