A 14-year-old aphakic girl who had had previous bilateral glaucoma surgery with a Molteno implant underwent pars plana vitrectomy and silicone-oil tamponade for proliferative-vitreoretinopathy retinal detachment in both eyes. The filtering bleb of the left eye was functional for 5 months before becoming available for histologic examination. We found numerous foreign-body granulomas coating the inner surface of the bleb, as well as intracellular and extracellular deposits of emulsified silicone oil in the wall of the bleb. In the fellow eye, the filtering bleb remained functional despite repeated vitreous surgery with silicone oil. Filtration in aphakic eyes with previous Molteno surgery and silicone-oil tamponade after vitrectomy may continue normally for a prolonged period of time, although emulsified oil droplets likely will have accumulated in the bleb and become incorporated in its fibrous capsule.
一名14岁的无晶状体女孩，此前接受过双侧青光眼手术并植入了莫尔顿引流盘，因双眼增殖性玻璃体视网膜病变性视网膜脱离接受了玻璃体切除术和平坦部硅油填充术。左眼的滤过泡在可供组织学检查前发挥功能达5个月。我们发现大量异物肉芽肿覆盖在滤过泡内表面，以及滤过泡壁内细胞内和细胞外的乳化硅油沉积物。在另一只眼中，尽管反复进行了硅油玻璃体手术，但滤过泡仍保持功能。在曾接受莫尔顿手术且玻璃体切除术后进行硅油填充的无晶状体眼中，滤过可能会在较长时间内正常持续，尽管乳化油滴可能会在滤过泡中积聚并融入其纤维囊。
