デスメ氏膜破裂及び欠損を伴う後部円錐角膜の1例

Keratoconus Posticus Associated with Rupture and Deficiency of Descemet's Membrane

I．緒言

　出産時に於ける眼外傷，殊に鉗子分娩による報告は枚挙に遑ない程であるが，私は最近鉗子分娩による後部円錐角膜の比較的稀な症例を診る機会があり，特異な病像を呈していたので，次に報告する。

The auther herein presents a case of keratoconus posticus associated with a wide-scoped detachment and deficiency of the Descemet's membrane caued by the use of forceps at the birth of the case—a boy of 8 years who was brought to our clinic with the main complaint of impaired sight.

In this case, the Descemet's membrane was almost entirely detached from the posterior surface of the cornea along a circular outline and standing off sail-wise free in the ante-rior chamber, with a hole at the center.
