良好な濾過胞をもつ術後50年の全層濾過手術の症例

Cases with functioning blebs fifty years after full-thickness filtering surgery

　71歳男性と75歳男性が視力低下で受診した。1例は65年前に先天緑内障と診断された。1眼は摘出，他眼にはScheieの全層濾過手術が行われ，受診時の矯正視力は0.5であった。他の1例は58年前に不発弾が爆発し，1眼は失明し，他眼は5年後に外傷性緑内障と診断され，管錐術が行われた。受診時の矯正視力は手動弁であった。2例とも上方に濾過胞が形成され，白内障が進行していた。2例に白内障手術と眼内レンズ挿入術を行い，経過は良好である。過去の緑内障手術の具体像を知ることができた症例である。

　Two males presented with decreased visual acuity. They were aged 71 and 75 years respectively. One had been diagnosed with congenital glaucoma 65 years before. One eye had to be enucleated. The other eye received full-thickness filtering surgery after Scheie. When seen by us,the visual acuity in the seeing eye was 0.5. The other case suffered explosion of a dud bomb 58 years before. One eye became blind. The other eye developed glaucoma 5 years later and received corneoscleral trephining. The visual acuity in the seeing eye was counting fingers. Both cases showed well-formed filtration bleb at the 12 o'clock position. We treated both cases by uneventful cataract surgery and intraocular lens implantation. These cases showed the state of glaucoma surgery more than half a century ago.
