A 31-year-old man sustained a 1,064-nm Q-switched Nd:YAG laser injury to his left eye. One month after the injury, the fundus and optical coherence tomography (OCT) examination demonstrated a full-thickness macular hole of approximately 820 μm in diameter. After vitrectomy and internal limiting membrane peeling, OCT showed closure of the hole and a marked thinning of the foveal depression. After 12 months of follow-up, his visual acuity improved from 20/60 to 20/20. The MP1-microperimeter demonstrated increased retinal sensitivity in the area of the previous macular hole and its adjacent region and improvement of fixation from a relatively unstable status to a stable status. The macular hole remained closed 24 months postoperatively with the best corrected visual acuity 20/20. Our results suggest that vitrectomy can improve the visual function when a macular hole is caused by Nd:YAG laser injury. The improvement in the visual function includes not only visual acuity but also retinal sensitivity and fixation stability that are obtained by using the MP1-microperimeter.
一名31岁男性左眼遭受1064纳米调Q开关钕:钇铝石榴石激光损伤。受伤1个月后，眼底及光学相干断层扫描（OCT）检查显示直径约820μm的全层黄斑裂孔。玻璃体切除及内界膜剥除术后，OCT显示裂孔闭合，黄斑中心凹明显变薄。随访12个月后，其视力从20/60提高到20/20。MP1微视野计显示，先前黄斑裂孔区域及其相邻区域的视网膜敏感度增加，注视从相对不稳定状态改善为稳定状态。术后24个月黄斑裂孔仍保持闭合，最佳矫正视力为20/20。我们的结果表明，当黄斑裂孔由钕:钇铝石榴石激光损伤引起时，玻璃体切除术可改善视功能。视功能的改善不仅包括视力，还包括使用MP1微视野计获得的视网膜敏感度和注视稳定性。
