1974年12月から1982年10月までに全国8療養所の癩患者を3カ所の療養所において,行った水晶体全摘出術は300名376眼(癩腫型361眼,類結核型およびその他15眼)であった.これらの眼に見られた癩眼合併症と手術後視力の改善率を検討した.
(1)手術眼に50%以上みられた合併症は兎眼(68%),角膜実質混濁(55%),縮瞳(84%),過去に虹彩炎(ぶどう膜炎)の既往歴のある眼(78%),虹彩後癒着(68%)である.
(2)兎眼があると手術後の視力の改善率は有意の差(P<0.10)でない眼より悪い.
(3)角膜実質混濁,角膜血管侵入,角膜上皮変化,虹彩前癒着,緑内障の癩眼合併症を有する眼では,有意の差(P<0.01)で手術後の視力の改善率が悪い.
(4)過去に虹彩炎のあった眼は,ありに有意の差(P<0.10)で手術後の視力の改善率が良い.
We performed intracapsular cataract extraction in 376 eyes, 300 patients, at three sanatoriums for the lepra during an 8-year period through 1982. The operated eyes had been affected by various compli-cations due to lepra : lagophthalmos 68%, corneal stromal opacity 55%, miosis 84%, history of uveitis78%, and posterior synechia of the iris 68%.
Postoperative visual acuity improved by more than 2 lines in 297 eyes (79%). There was no improvement or even deterioration in vision in 45 eyes (12%). The postoperative visual acuity was implicated by lagophthalmos (p<0.10), and either of corneal opacity, corneal vascularization, band-shaped corneal degeneration, anterior synechia or glaucoma (p<0.01 for each). The prognosis con-cerning the postoperative visual acuity was not affected by miosis or posterior synechia.
