Purpose:
To report the use of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser internal limiting membranotomy to successfully treat the first reported case of subinternal limiting membrane (sub-ILM) hemorrhage that developed after coil embolization of a cerebral aneurysm.
Case Report:
A 59-year-old Korean woman visited our clinic complaining of central scotoma in her left eye, which developed shortly after stent-assisted coil embolization of an unruptured internal carotid artery aneurysm. Fundus examination revealed a sub-ILM hemorrhage in her left eye, and after 2 days, a Nd:YAG laser membranotomy was performed with a single 4.5-mJ burst. There was a marked reduction in the sub-ILM hemorrhage 1 day after Nd:YAG laser membranotomy, and after 1 month, her best-corrected visual acuity improved to 20/20, with complete resolution of the sub-ILM hemorrhage.
Conclusions:
Sub-ILM hemorrhage can develop after coil embolization of a cerebral aneurysm, and Nd:YAG laser internal limiting membranotomy can be a useful noninvasive treatment alternative to surgical intervention.
