Diabetic retinopathy is an important cause of severe vision loss. The risk of vision loss from diabetic retinopathy is substantially reduced by intensive control of diabetes and appropriate laser surgery for proliferative diabetic retinopathy and diabetic macular edema.
The Diabetic Retinopathy Vitrectomy Study (DRVS) helped identify the indications and most propitious time for performing diabetic vitrectomy for nonresolving vitreous hemorrhage. The DRVS also highlighted the risks and potential complications of vitrectomy surgery.
Diabetic persons with severe vision loss from severe proliferative diabetic retinopathy are candidates for vitrectomy after vitreous hemorrhage and severe fibrous changes in the retina.
In cases in which vision loss occurs, pars plana vitrectomy frequently can restore useful vision, and reduce the risk of vision loss from traction retinal detachment.
糖尿病视网膜病变是导致严重视力丧失的重要原因。通过强化控制糖尿病以及对增殖性糖尿病视网膜病变和糖尿病黄斑水肿进行适当的激光手术,可大幅降低糖尿病视网膜病变导致视力丧失的风险。
糖尿病视网膜病变玻璃体切除术研究(DRVS)有助于确定对无法吸收的玻璃体积血进行糖尿病玻璃体切除术的适应症和最佳时机。DRVS还强调了玻璃体切除手术的风险和潜在并发症。
患有严重增殖性糖尿病视网膜病变且视力严重丧失的糖尿病患者,在出现玻璃体积血和视网膜严重纤维变性后可考虑进行玻璃体切除术。
在发生视力丧失的病例中,平坦部玻璃体切除术常常能够恢复有用视力,并降低牵引性视网膜脱离导致视力丧失的风险。
