A case of traumatic anitidia with subconjunctival luxation of the lens.

I．緒言

　外傷性無虹彩症は比較的稀な疾患であるが，私共は，最近水晶体球結膜下脱臼を伴つた一例を経験したので，茲に御報告し，更に水晶体球結膜下脱臼の機転につき少しく考察したいと考える次第である。

A report is presented over a case of trau-matic aniridia in a 50-year-old male patient. Repeated blow had been inflicted upon the left eye with the tip of the umbrella when involved in a quarrel. For a while after the injury, the case simulated traumatic aniridia without the rupture of the globe which is an exceptionally rare event. As time passed, it be-came evident that the condition was accom-panied by luxation of the lens into the sub-conjunctival space. It was assumed by the authors that the lens together with the iris had got out of the globe through the site of the indirect scleral rupture.
