Unilateral Stage 1A Macular Hole Secondary to Low-Energy Nd:YAG Peripheral Iridotomy.

Macular hole formation is a rare complication of laser peripheral iridotomy (LPI) and may cause permanent scotomas. This case describes macular hole formation after 2.8 mJ Nd:YAG laser energy application in a patient with vitreomacular attachment. A literature review of a limited number of case reports shows that older patients who developed holes after LPI had more visually-significant and advanced stage holes that required surgical retinal repair, whereas younger patients had less visually-significant and mild stage holes with a spontaneous resolution on optical coherence tomography (OCT).
