要約 目的:ルアーフィッシング用の釣り針が角膜を穿孔し,虹彩根部まで損傷が及ぶ症例を経験したので報告する。
症例:49歳,男性がルアー釣り針による左眼の穿孔性眼外傷で受診された。初診時視力は左手動弁で,釣り針の先端は角膜を穿孔し,隅角に達していた。外来顕微鏡にてcut-out法により,釣り針を摘出し,その後手術室で角膜縫合と抗菌薬入り緩衝塩類溶液で前房内洗浄を行った。術後,外傷性白内障や他の重篤な眼合併症はみられず,術後6か月で視力は(1.5)に回復した。
結論:釣り針における眼外傷では,適切な摘出方法と摘出までの迅速さが重要である。本症例は,釣り針の迅速な摘出と二期的な手術治療により良好な治療経過が得られた。
Abstract Purpose:We report a case of corneal perforation caused by a lure fishing hook, resulting in damage to the root of the iris.
Case and Findings:A 49-year-old man presented with a perforation of the left eye caused by a lure fishing hook. At initial examination, his left best corrected visual acuity was hand motion. The tip of the hook had perforated the cornea and reached the root of the iris. The fishhook was removed by the cut-out technique under the microscope in the clinic. The corneal suture was then placed, followed by intracameral irrigation with buffered saline solution containing antibiotics in the operating room. Postoperatively, no traumatic cataract or other serious ocular complications were observed, and 6 months postoperatively, his left visual acuity improved to 1.5.
Conclusions:Appropriate and prompt extraction is vital for eye injuries caused by fishing hooks. This patient recovered well owing to the prompt removal of the hook and two-stage surgical treatment.
