PurposeTo记录和评估术前和术后黄斑视网膜电图的变化在接受手术引流的黄斑下hemorrhages.Methods5例患者的5眼视力良好的发病前出血进行了玻璃体切除术后3至14天发展出血，引流黄斑下出血，使用重组组织纤溶酶原激活剂。视网膜下出血的原因是大动脉瘤在三只眼睛，年龄相关性黄斑变性在一只眼睛，和一只眼睛未知。视力和黄斑视网膜电图记录术前和postoperation.ResultsIn所有的眼睛，术前视网膜电图反应显着减少或无法记录。术后视力提高，视网膜电图反应恢复到约一半的幅度，在每只眼睛与一个正常的fellow eye.ConclusionsA几乎nonrecordable术前黄斑视网膜电图的反应表明严重的功能障碍的黄斑下出血引起的光感受器。术后恢复的黄斑视网膜电图表明，光感受器功能至少部分可逆的手术干预，包括注射重组组织纤溶酶原激活剂到视网膜下腔。
PurposeTo record and evaluate change in preoperative and postoperative macular electroretinograms in patients undergoing surgical drainage of macular subretinal hemorrhage.MethodsFive eyes of five patients with good visual acuity before onset of hemorrhage underwent vitrectomy between 3 and 14 days after developing hemorrhage, with drainage of submacular hemorrhage, using recombinant tissue plasminogen activator. The causes of subretinal hemorrhage were macroaneurysm in three eyes, age-related macular degeneration in one eye, and unknown in one eye. Visual acuity and macular electroretinograms were recorded preoperatively and postoperatively.ResultsIn all eyes, preoperative electroretinographic response was remarkably reduced or not recordable. Postoperative visual acuity improved, and electroretinographic response recovered to about one half the amplitude of the fellow eye in every eye with a normal fellow eye.ConclusionsA nearly nonrecordable preoperative response on macular electroretinogram indicates severe dysfunction of the photoreceptors caused by the submacular hemorrhage. A postoperative recovered macular electroretinogram suggests that photoreceptor function is at least partially reversible with surgical intervention, including injection of recombinant tissue plasminogen activator into the subretinal space.
