Vitreoretinal and anterior segment surgery through the pars plana: part I.

摘要: Instrumentation and clinical experience dealing with intraocular surgery through a pars plana approach have advanced rapidly during the past 5 years. These techniques been used to successfully treat number of ocular disorders. Considerable this form has accumulated, results incidence complications are similar among centers. Additional refinements in instrumentation surgical will probably expand capabilities further improve surgery. However, we approaching point at which primary limiting factor be pathophysiology diseases rather than or skill. The ability vision by removing persistent opacities media demonstrated, follow-up 2 more years shown that eye can continue function well after excision formed vitreous. indication for vitreous proven most difficult hazardous is treatment complicated rhegmatogenous retinal detachments elevated, mobile retina presents special problems. role vitrectomy management proliferative diabetic retinopathy early penetrating injuries involving posterior segment clinical-research objectives immediate future. In these conditions may useful alter course progressive vitreoretinal pathology as being previously existing complications. Finally, our risk significant present every case performed approach. mechanical minimized careful attention detail surgery, but cannot eliminated. Retinal detachment frequent potentially blinding complication, surgeon should skilled breaks detachment. Also, there biologic complications, including rubeosis iridis, occur following technically successful certain eyes. Rubeosis iridis major problem eyes because it destroy functional an otherwise operation, no effective now known. Hopefully, research efforts understanding pathogenesis disorder permit us develop means prophylaxis treatment.
