We treated two cases of retinal phototoxic damage created by the coaxial illumination of the operating microscope during vitrectomy surgery. These lesions were probably created at the end of the vitrectomy procedure, after intraocular manipulation had ceased. This critical period, while the sclerotomy sites were being closed, was estimated to last no longer than ten to 15 minutes. We recommend that the cornea be shielded during sclerotomy closure at the conclusion of those vitrectomy procedures with a clear liquid media and clear crystalline lens or pseudophakos.
我们治疗了两例在玻璃体切割手术期间因手术显微镜同轴照明造成的视网膜光毒性损伤病例。这些损伤可能是在玻璃体切割手术结束时、眼内操作停止后造成的。据估计，在巩膜切开部位闭合的这个关键时期持续时间不超过10至15分钟。我们建议，在那些有透明晶状体或人工晶状体的玻璃体切割手术结束时，在巩膜切开部位闭合期间用透明液体介质遮挡角膜。
