Amsler grid examination and optical coherence tomography of a macular hole caused by accidental Nd:YAG laser injury

Am J Ophthalmol. 2000 Sep;130(3):355-6. doi: 10.1016/s0002-9394(00)00547-x.

Abstract

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 microm 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.
