Today, the widespread use of laser instruments in various fields has resulted in many accidental retinal injuries. Here we describe a rare clinical case of full-thickness macular hole (MH) and focal choroidal excavation (FCE) caused by a 1064-nm Q-switched Nd:YAG laser. After pars plana vitrectomy and the following 14 months, consecutive optical coherence tomography imagings showed closure of the MH. Visual acuity improved even in the absence of the outer retina and in the presence of FCE. We speculate that different focusing effects of the unexpected Nd:YAG laser which target different levels of retinal tissue generates diverse prognosis.
