水晶体破裂例に対する新しい硝子体手術

A new surgical technique for removing the lens nucleus dislocated into vitreous

　鈍的外傷により水晶体前後嚢とも破裂し，前房・硝子体中に散乱した水晶体片により強い水晶体性眼内炎と続発性緑内障をおこした極めてめずらしい症例を経験した。硝子体中に落下した水晶体核の摘出に際し，角膜をトレパンでくりぬき，術中冷却保存液中に保存し，開創部よりopen sky vitrectomyを行うという新しい術式を採用し，広い視野の下に安全に核を摘出しえた。術後良好な視力が得られ，手術による角膜内皮の損傷も軽度であった。本術式は硝子体中に落下した水晶体核の摘出に際し有用な力法である。

A 44-year-old man had his lens capsule ruptured by ocular blunt trauma. Scattering lens mass gave rise to severe lens-induced uveitis and phacolytic glaucoma. For the purpose of removing the resid-ual lens nucleus in the vitreous, open-sky vitrec-tomy was carried out. New technique of vitreous surgery was chosen. Following trephination of the cornea, the cornea was preserved in cold modified M-K medium. Open-sky vitrectomy was performed through the corneal incision using Vitrophage. Balanced salt solution was used as irrigating solu-tion. Lens nucleus was safely extracted with vitre-ous cryoprobe.
