緒言
水晶体が硝子体内,前房内あるいは結膜下に脱臼することは眼外傷の中で頻度の高いものではないが,さりとてまれなものでもない1)。
外傷の力,方向および加わり方によつて水晶体脱臼の程度はいろいろで,軽度なものでは視機能に及ぼす影響も少なく,対症療法のみで軽快をみる症例もある。しかし重大な合併症,ことに続発性緑内障や水晶体性ブドウ膜炎を伴う際には,ただちに水晶体を摘出すべきか否かの判断に迫られる。この点についてはすでにChandler2),Cal—houn et al.3)らの詳細な報告がある。
A total of 29 cases who had been admitted and treated to our clinic between the year 1962 and 1972 with the diagnosis of traumatic dis-located lens were studied.
The duration of dislocation in these cases varied from one day to 16 years. The length of follow-up varied from 5 months to 9 years with an average duration of about three years. The age of the patients varied from 16 to 77 yearswith an average age of 51 years. All of the luxated lenses were unilateral, 28 of them with luxation into the vitreous and 18 of these with subluxations.
