Abstract
Choroidal neovascularization (CNV) secondary to Nd:YAG laser macular injury consists of a rare condition without standardized treatment. Herein, we present the long-term outcomes of a case with a spontaneous closure of a laser-associated macular hole that was followed by late-onset CNV and was successfully treated with intravitreal ranibizumab. A 32-year-old man suffered a macula injury in his right eye after accidental exposure to an 800-nm wave length Nd:YAG laser pulse. Ophthalmological examination demonstrated deterioration in visual acuity along with parafoveal and post-hyaloid hemorrhage. After 1 month, fundoscopy indicated the formation of a full-thickness macular hole. A close observation revealed spontaneous closure of the hole and visual improvement within the next month. One and a half year later, the patient presented with sudden visual distortion, while optical coherence tomography and fluorescein angiography disclosed the development of CNV. The patient was successfully treated with a single intravitreal injection of ranibizumab. The patient’s condition has remained stable during an 8-year follow-up period. In conclusion, laser-induced macular injury consists of an increasingly remarkable condition that may have a profound impact on visual outcomes. Our case provides insight into the potential mechanisms of Nd:YAG laser injury and its complications, indicating that CNV may occur even in the long term, while anti-vascular endothelial growth factor may help maintain stable anatomic and functional outcomes.
