不作凝固的视网膜脱离巩膜外垫压术

采用不作凝固的手术方法治疗裂孔性视网膜脱离10例,全部病例用硅胶海绵作巩膜外蛰压。其中一例放出视网膜下积液。除一例因缝线松脱,垫压物移位而失败外,其余一次治愈。随访平均20个月,未复发。本术式的优点是①简化手术步骤,缩短手术时间。②避免热凝引起的巩膜坏死,有利再手术。③术毕玻璃体、视网膜等组织反应轻,术后无明显视网膜、脉络膜萎缩,避免了永久性视机能障碍。④术后色素膜及外眼反应轻,病人痛苦小。此外,对本法适应证和作用机制作了初步讨论。

EXTERNAL SCLERAL INDENTATION SURGERY OF RETINAL DETACHMENT WITHOUT COAGULATION

Surgical procedures for rhematogenous retinal detachment were performed with- out diathermy or cryotherapy in 10 cases. In all casein, the sclera was depressed with local silicone sponge implant. The subretinal fluid was drained in one of the 10 cases. Except one displacement due to loosened suture all the operations are successful in the original surgeries. No relapse took place in the follow-up peri- od 20 months average The advantages of this procedure are: (1)The operation is simplified and the time is shortened. ( 2 ) It avoids the necrosis of sclera cau- sed by diathermy so as to facilitate the reoperation. (3)After the operation, the reaction of vitreous, retinal and other tissues is slight, without obvious atrophy of the retina and choroid, the patient operated on can be prevented from perma- nent vision malfunctioh, (4)After the operation, the reaction of the uveal fract and extraocular is so slight that the patient is relieved of sufferings. The indication and the mechanism for the procedure is discussed preliminarily.
