Island membrane surgery in advanced proliferative diabetic retinopathy Application

Abstract

Objective To investigate the late stage of proliferative diabetic retinopathy with neovascular membrane on the surface of the optic disc or the upper and lower surface of the large blood vessels bow, and the surgery skill for the vitreous hemorrhage or traction retinal detachment or combined traction rhegmatogenous retinal detachment, and to explore surgery techniques of the stripping film, and the treatment value of vitreous surgery on these patients.Methods A total of 106 cases (106 eyes) patients with advanced proliferative diabetic retinopathy were included in this study.Male cases were 47 (47 eyes), female cases where 59 (59 eyes), age was 44-69 years old.Traditional membrane tear film technology was used on the early treatmerit of membrane on 55 cases (55 eyes) were used this technique, while the island membrane technology was used on the late stage treatment on cases (51 eyes).Results Visual acuity improved better on island membrane group than the tear film group post-operatively, however, the best visual acuity was not better than 0.12 due to the both group of the patients were on the later stage.The majority of visual acuity was between 0.02-0.08.Intraoperative and post-operative complication was significant lower on the island membrane technology group that decreased the silicone oil fill rate and reduced the possibility of secondary surgery.Conclusions The island membrane technology are better than the traditional technology to remove the film on advanced proliferative diabetic retinopathy, vitreous hemorrhage and retinal detachment.Some visual function is able to restore after vitrectomy so there is still a great therapeutic value.
