外傷性前房出血に合併した角膜血染症の1例

A case of blood staining of the cornea secondary to traumatic hyphema

　外傷性前房出血に合併した角膜血染症の1例を報告した。その原因は受傷後4日目に発生した二次性前房出血と続発性緑内障であった。強角膜切開創から凝血塊の圧出を行ったにもかかわらず，角膜血染症による角膜の混濁の消失には約17か月の長期間を要した。

　以上のことから外傷性前房出血を認めた場合，受傷後1週間は安静を保ち，角膜血染症の原因となりやすい二次性前房出血の防止に努めることが重要であることを強調した^1）。

A 17-year-old male sought medical advice 5 days after suffering from blunt trauma to the right eye by flying soccer ball. He did not keep rest in spite of visual failure soon after the injury. Ocular pain, nausea and vomiting developed the day before visiting us. Rraised intraocular pressure and mas-sive hyphema in the right eye was observed. Cor-neal blood staining developed on 12 days after theinjury. We succeeded in complete removal of blood clot in from the anterior chamber through limbal incision 15 days after the injury. The intraocular pressure returned to normal. The corneal blood staining cleared 17 months later. We advocate thatpatient with traumatic hyphema observe strict bed rest in order to prevent recurrence of hyphema.
