After preoperative assessment revealed anomalous posterior vitreous detachment, a 75-year-old woman affected with retinal detachment due to macular hole was scheduled to undergo the posterior episcleral buckling procedure. Preoperative microperimetry showed unstable eccentric fixation with a dense scotoma within the central 8 degrees. One month postoperatively, best-corrected visual acuity increased from 1.70 to 0.88 logarithm of the minimum angle of resolution. Ultrasonography and optical coherence tomography revealed the indentation of the posterior scleral profile due to the buckle. The retina appeared fully attached and a macular hole with flattened edges was still detectable. Microperimetry showed stable central fixation with recovery of retinal sensitivity within the central 2 degrees. Diagnostic imaging techniques guided the decision to use the posterior episcleral buckling procedure. Microperimetry was useful to explain vision improvement despite residual macular hole.
术前评估显示存在异常的玻璃体后脱离，一名因黄斑裂孔导致视网膜脱离的75岁女性被安排接受巩膜外环扎术。术前微视野检查显示偏心注视不稳定，中央8度范围内有致密暗点。术后1个月，最佳矫正视力从1.70对数最小分辨角提高到0.88对数最小分辨角。超声检查和光学相干断层扫描显示由于环扎导致后巩膜轮廓凹陷。视网膜看起来完全复位，仍可检测到边缘变平的黄斑裂孔。微视野检查显示中央注视稳定，中央2度范围内视网膜敏感度恢复。诊断成像技术指导了巩膜外环扎术的决策。尽管存在残留黄斑裂孔，微视野检查有助于解释视力的改善情况。
