Central retinal-artery obstruction (CRAO) is a devastating complication after retrobulbar anesthesia, a procedure which was previously recommended routinely to immobilize the eye and reduce discomfort during laser surgery. Recent developments in treatment technique, involving scatter laser applications given over several sessions with smaller spot sizes and shorter durations, have virtually eliminated the need for retrobulbar injections and the risks of retrobulbar hemorrhage, which can cause increased intraocular pressure and culminate in closure of the arterial circulation. We present the case of a patient with proliferative sickle retinopathy who sustained such a complication after direct photocoagulation treatment of sea-fans elsewhere and offer alternative treatment techniques which we have used for the past ten years that eliminate this hazard.
视网膜中央动脉阻塞（CRAO）是球后麻醉后的一种严重并发症，球后麻醉此前常用于使眼球固定，以减轻激光手术期间的不适。治疗技术的最新进展，包括多次采用较小光斑尺寸和较短持续时间进行散射激光治疗，实际上已不再需要进行球后注射，也消除了球后出血的风险，球后出血可导致眼压升高，最终致使动脉循环闭塞。我们报告一例增殖性镰状视网膜病变患者的病例，该患者在别处对海扇状病变进行直接光凝治疗后出现了这种并发症，并提供了我们在过去十年中使用的替代治疗技术，这些技术可消除这种风险。
