外傷性毛様体解離による低眼圧症2例の外科的療法

Surgical treatment of two cases with ocular hypotony due to traumatic cyclodialysis

（1）外傷性毛様体解離による低眼圧症の2例を経験し，外科的治療を施行した．

（2）1例目は受傷後2カ月半目に，ジアテルミー凝固，人工的虹彩前癒着形成術，硝子体中空気注入による併用手術を施行した．2例目は受傷後1年8カ月目に，人工硝子体液注入とジアテルミー凝固を施行した．

（3）2症例とも術後一過性の眼圧上昇発作（1例目は術翌日，2例目は1年3カ月）の後，眼所見の著しい改善がみられた．

（4）眼圧上昇の原因は房水の上脈絡膜腔への流出路の閉鎖によるものと考えた．

We treated two cases of persistent ocular hypotony maculopathy due to traumatic cyclodialysis. In the first case, the chamber angle cleft was closed by cyclodia-thermy and suturing the peripheral iris through a small scleral incision. Intravitreal air injection was performed at the end of surgery. In the second case, we performed cyclodiathermy with additional intravitreal fluid injec-tion. Both cases responded favorably after a transient rise in intraocular pressure during the initial postoper-ative period.

As rationale for our present surgical approach, the cleft in the chamber angle had to be closed as it allowed the aqueous to flow into the suprachoroidal space.
