光学相干断层成像术显示的近视性黄斑病变影像:北京眼病研究
Abstract
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 of 50 years or more.
METHODS:
The participants underwent a detailed ophthalmic examination including OCT with enhanced depth imaging of the macula.
MAIN OUTCOME MEASURES:
Optical coherence tomography features of the macula in highly myopic eyes defined by a refractive error of -6 diopters or less or an axial length of 26.5 mm or more.
RESULTS:
Readable OCT images were available for 6530 eyes (94.5%) of 3278 participants. The most common change in the macula was maculoschisis (0.8±0.1%), followed by incomplete posterior vitreous detachment (0.7±0.1%), disruption of the photoreceptor inner segment/outer segment interface (0.6±0.1%), epiretinal membranes (0.6±0.1%), macular defects in Bruch's membrane (0.3±0.1%), clumping of the retinal pigment epithelium (0.2±0.1%), vitreofoveal adhesion (0.2±0.1%), and macular holes in 2 eyes (0.1±0.1%). Prevalence of any myopic maculopathy per eyewas 112 of 6530, or 1.71±0.16% (95% confidence interval [CI], 1.40-2.03). After adjustment for longer axial length (P<0.001; odds ratio [OR], 2.68; 95% CI, 1.97-3.64) and myopic refractive error (P<0.001; OR, 0.63; 95% CI, 0.55-0.73), presence of any myopic maculopathy was not significantly associated with any systemic variables (all P≥0.05), including biochemical blood examination and ocular parameters. Best-corrected visual acuity was associated significantly with the absence of a disruption of the photoreceptor inner segment/outer segment interface (P<0.001), epiretinal membranes (P<0.001), and macular holes (P<0.001) after adjustment for age and cylindrical refractive error.
CONCLUSIONS:
Based on OCT examination, the most common macular change in highly myopic eyes was maculoschisis, followed by incomplete posterior vitreous detachment, disruption of the photoreceptor inner segment/outer segment interface, epiretinal membranes, macular defects in Bruch's membrane, clumping of the retinal pigment epithelium, vitreofoveal adhesion, and macular holes. The most important macular changes with a negative effect on best-corrected visual acuity were a disruption of the photoreceptor inner segment/outer segment interface and epiretinal membranes.
