サリン曝露後にみられた瞼球癒着

A case of symbrepharom after minimal exposure to sarin gas

　1995年3月20日に東京で発生した地下鉄サリン事件の直後に，33人の被害者が当院を受診した。全員が軽症であり，全身的に異常はなかったが，17名に極度の散瞳があった。その一人である49歳男子に結膜充血が持続し，3か月後に両眼の瞼球癒着が生じた。瞼球癒着とローズベンガル染色は，鼻側結膜でより顕著であった。被曝による細胞毒性が原因となった結膜壊死がその原因であると推測された。

A major sarin incident occurred in the subway system in Tokyo on March 20, 1995. More than 5,000 persons were injured with lethal outcome in 11 people. We treated 33 affected persons immediately after the incident. All were diagnosed as apparently normal systemically. Severe miosis was present in 17.A 49-year-old male, who was one of the 17 victims with miosis, developed persistent conjunctival hyperemia.Bilateral symblepharon occurred 3 months later. The nasal portion of bulbar conjunctiva showed severer symblepharon and rose bengal staining. Toxic necrosis of the conjunctiva was suspected as the cause.
