To describe the clinical picture in eyes that developed vitreous opacification behind the intraocular lens (IOL) after neodymium:YAG (Nd:YAG) laser posterior capsulotomy and determine whether this type of opacification tends to occur in patients with diabetes.
Shinjo Eye Clinic, Miyazaki, Japan.
The clinical course in 728 eyes that had Nd:YAG posterior capsulotomy was reviewed.
After Nd:YAG posterior capsulotomy, opacification developed in the vitreous in contact with the IOL in 9 eyes (1.2%). All occurred in diabetic patients, and the vitreous opacification developed within 1 month after the capsulotomy. A vitrectomy was performed in 8 eyes and in 1, the opacification spontaneously absorbed. Vitreous opacification occurred in 8.9% of 101 eyes of diabetic patients, and the prevalence in diabetic eyes was significantly higher than in nondiabetic eyes (P < .0001). Nine of the diabetic eyes were opaque and 92 nonopaque. In the opaque eyes, the prevalence of panretinal photocoagulation was higher than in the nonopaque eyes (P = .013), and hemoglobin Alc (P = .030) was higher; the interval between cataract surgery and Nd:YAG capsulotomy was shorter (P = .047) and the final visual acuity, lower (P = .045).
The prevalence of vitreous opacification after Nd:YAG laser posterior capsulotomy was significantly higher in diabetic than in nondiabetic eyes. Viterectomy was effective for this type of opacification.
描述钕：钇铝石榴石（Nd:YAG）激光后囊切开术后人工晶状体（IOL）后玻璃体混浊的眼部临床表现，并确定这种混浊是否倾向于在糖尿病患者中发生。
日本宫崎新庄眼科诊所。
回顾了728只接受Nd:YAG后囊切开术的眼睛的临床过程。
Nd:YAG后囊切开术后，9只眼睛（1.2%）的与IOL接触的玻璃体出现混浊。所有病例均发生在糖尿病患者中，且玻璃体混浊在囊切开术后1个月内出现。8只眼睛进行了玻璃体切除术，1只眼睛的混浊自行吸收。101只糖尿病患者的眼睛中有8.9%出现玻璃体混浊，糖尿病眼的患病率显著高于非糖尿病眼（P <.0001）。9只糖尿病眼混浊，92只不混浊。在混浊眼中，全视网膜光凝的患病率高于不混浊眼（P =.013），糖化血红蛋白（P =.030）更高；白内障手术与Nd:YAG囊切开术之间的间隔更短（P =.047），最终视力更低（P =.045）。
Nd:YAG激光后囊切开术后糖尿病眼玻璃体混浊的患病率显著高于非糖尿病眼。玻璃体切除术对这种类型的混浊有效。
