To report a case of a macular microhole of an outer retinal defect that resolved spontaneously during visualization of the sequential anatomic changes on optical coherence tomography (OCT) before and after detachment of the posterior hyaloid from the fovea. The patient was a 47-year-old woman with a central scotoma and metamorphopsia. OCT 3 detected a small outer retinal defect, a so-called macular microhole. The OCT ophthalmoscope showed an elevated foveal photoreceptor layer with a perifoveal posterior vitreous detachment (PVD) at the initial visit. Six months later, both OCTs showed resolution of the photoreceptor layer abnormality and detachment of the posterior hyaloid from the fovea. The photoreceptor layer abnormality and visual symptoms resolved almost simultaneously. These findings may explain that the elevated foveal photoreceptor layer associated with the perifoveal PVD could be the anatomic mechanism responsible for macular microhole formation.
报告一例黄斑部外层视网膜缺损性微小孔病例，该病例在玻璃体后脱离从黄斑中心凹脱离前后的光学相干断层扫描（OCT）观察到的连续解剖变化过程中自发消退。患者为一名47岁女性，有中心暗点和视物变形。OCT 3检测到一个小的外层视网膜缺损，即所谓的黄斑微小孔。初次就诊时，OCT检眼镜显示黄斑中心凹光感受器层抬高，伴有黄斑中心凹周围玻璃体后脱离（PVD）。6个月后，两次OCT均显示光感受器层异常消退，玻璃体后脱离从黄斑中心凹处脱离。光感受器层异常和视觉症状几乎同时消退。这些发现可能解释了与黄斑中心凹周围PVD相关的黄斑中心凹光感受器层抬高可能是黄斑微小孔形成的解剖学机制。
