Results The retinae were attached in all the cases after operation. During the follow-up period of three months to three years, ten eyes kept the retina attached and three cases suffered from recurrent retinal detachment. One of them had had a second surgical procedure and obtained retinal re-attachment.

结果 13只眼术后视网膜均复位，3个月至3年随访期间，10例视网膜保持平复；3例视网膜脱离复发，其中1例经再次手术使视网膜复位；解剖学复位结果为11/13，术后和随访时视力有不同程度提高。

Retinal ischemia is a common cause of visual impairment and blindness . At the cellular level , ischemic retinal injury consists of a self-reinforcing destructive cascade involving neuronal depolarisation , calcium influx and oxidative stress initiated by energy failure and increased glutamatergic stimulati on .

视网膜缺血是一常见的引起视觉损害和致盲的原因，在细胞水平上，缺血性视网膜损伤由一系列自我加强破坏性的级联放大反应组成的，包括神经元去极化，钙流入和起源于能量缺少和谷氨酸刺激的氧化应激反应。

Furthermore, the nature of adhesive interactions between the RPE and BM are instrumental in the development of retinal detachments and proliferative retinal disease.

此外，RPE和BM之间的粘附功能对视网膜脱离和增生性视网膜病变的发展起重要作用。

Influence of the antioxidants vitamin E and idebenone on retinal cell injury mediated by chemical ischemia, hypoglycemia, or oxidative stressRego A, SantosM, Oliveira C.. Free Radic. Biol. Med, 1999, 26: 1405 - 1417Abstract:A role for the antioxidants vitamin E and idebenone in decreasing retinal cell injury, after metabolic inhibition induced by chemical ischemia and hypoglycemia, was investigated and compared with oxidative stress conditions.

对由于化学贫血与低血糖所引起的代谢抑制后，抗氧化剂维生素E与艾地苯醌视网膜细胞受损所引起的作用进行了研究，同时并与氧化应激情况进行了对比，对氧化物维生素E(20 microM)和艾地苯醌(10 microM)进行先期培养可以在氧化应激或低血糖后防止视网膜细胞受损，而对上述二种抗氧化剂给予预先培养后带来的保护作用则有所减低。
