摘要：

PURPOSE: To compare a macular hole from accidental Nd:YAG laser injury with idiopathic macular holes, METHODS: Case report. In a 24-year-old man with accidental Nd:YAG laser injury, right eye, Amsler grid testing and optical coherence tomography were performed, RESULTS: Nd:YAG laser injury was responsible for a macular hole about 700 mu m in diameter. The visual acuity was 20/100, Amsler grid testing displayed a central scotoma with no surrounding distortion. Optical coherence tomography showed a defect in all retinal layers at the macula. CONCLUSION: The scotoma caused by Nd:YAG laser injury is not surrounded by distortion; the hole is produced by the defect of all retinal layers. In contrast, idiopathic macular holes generally produce a pincushion pattern on Amsler grid testing and have no tissue loss. (C) 2000 by Elsevier Science Inc. All rights reserved.
