外傷性毛様体解離による低眼圧症の解離部レーザー光凝固による治療例

Laser photocoagulation in hypotonic maculopathy due to traumatic cyclodialysis

　外傷性毛様体解離によって発生した低眼圧症に対し，毛様体解離部にレーザー光凝固を行い，低眼圧を回復し，眼底所見と視力の改善をみることができた．本症例の毛様体解離は範囲が約60°で比較的狭く，このような例に対しては，反復追加可能で，侵襲の少ない解離部へのレーザー光凝固をまず試みるのがよいと思われた．

A 17-year-old male developed persistent hypotonic maculopathy due to traumatic cyclodialysis when his right eye was hit by a flying piece of fireworks. Gonios-copically, cyclodialysis was present over an arc of 60 degrees in the superior segment of the angle.

Ten weeks after the trauma, we applied photocoagulation to the site of cyclodialysis with a view to cure ocular hypotony. Five days after applying a total of 173 burns in two sessions, the intraocular pressure started to rise followed by improvement in hypotonic maculopathy and visual acuity during the ensuing 2 months.

Laser photocoagulation appears to be a preferred mode of treatment for ocular hypotony of traumatic origin because of its lesser insult to the eye and because of its repeatability.
