The management of three patients with aphakic bullous keratopathy by means of pars plana vitrectomy is described. The patients had previously undergone uneventful intracapsular cataract extraction with intact vitreous face. Eventual herniation of the vitreous into the anterior chamber with resultant corneal endothelial touch caused the corneal edema in all three cases. Pars plana vitrectomy resulted in resolution of photophobia and irritation. The visual acuity improved from 20/200, 20/200 and 20/70 to 20/70, 20/60 and 20/40 respectively. The central cornea was cleared of edema in all three cases. The final vision was limited in two of the patients by the persistence of preoperative cystoid macular edema. Pars plana vitrectomy may be used in the management of selected cases of aphakic bullous keratopathy from vitreous touch.
本文描述了通过平坦部玻璃体切除术治疗三例无晶状体大泡性角膜病变患者的情况。这些患者此前均接受了囊内白内障摘除术,术中玻璃体前界膜完整,手术过程顺利。最终,玻璃体疝入前房,导致角膜内皮接触,进而引起了这三例患者的角膜水肿。平坦部玻璃体切除术使畏光和刺激症状得到缓解。视力分别从20/200、20/200和20/70提高到了20/70、20/60和20/40。三例患者的中央角膜水肿均消退。其中两例患者的最终视力受术前黄斑囊样水肿持续存在的限制。平坦部玻璃体切除术可用于治疗因玻璃体接触导致的部分无晶状体大泡性角膜病变病例。
