Laser iridotomy is the procedure of choice for primary angle-closure glaucoma. The authors report a new visual disturbance after neodymium (Nd): YAG laser iridotomy. Thirteen patients presented with monocular blurring or a bluish or colored line after the laser procedure. Each eye had a patent iridotomy partially exposed by the upper lid. When the iridotomy was fully covered or fully exposed, symptoms disappeared. Symptoms also were relieved with tinted lenses. The authors suggest close preoperative examination with careful placement of the laser iridotomy entirely under the upper lid to prevent this potential visual disturbance.
激光虹膜切开术是原发性闭角型青光眼的首选治疗方法。作者报告了钕（Nd）:YAG激光虹膜切开术后一种新的视觉障碍。13例患者在激光治疗后出现单眼视物模糊或出现蓝色或彩色线条。每只眼睛的虹膜切开术通畅，部分被上睑覆盖。当虹膜切开术被完全覆盖或完全暴露时，症状消失。戴有色眼镜也可缓解症状。作者建议术前进行仔细检查，将激光虹膜切开术小心地完全置于上睑下方，以预防这种潜在的视觉障碍。
