Scleral buckling (SB)単独で治療された353眼のmassive proliferative vitreoreti—nopathy (PVR)(grade D)をrctrospectiveに分析し次の結果を得た。
(1)網膜の復位率はPVRが重症なほど有意に低下し(D−1-51.2%,D−2-43.3%,D−3-24.7%),全症例では42.5%であった。
(2)大裂孔,脈絡膜剥離,硝子体出1血は復位率を有意に低下させた。
(3)復位例の81.3%に指数弁以上の視力を得,復位例の術後視力は術前PVRの重症度と相関を示さなかった。
(4) SB単独療法はmassive PVRに対して一定の治療効果を有することが明らかとなり,PVRの治療上,基本的に重要な役割を果たすことが実証された。
From 1956 to 1966, 353 eyes with massive pro-liferative vitreoretinopathy (PVR, Grade D) were treated with scleral buckling alone without using silicone oil or hyaluronic acid. The retina was reattached for at least 6 months in 42.5% of eyes and the anatomic success rate decreased significant-ly with increasing severity of PVR. Eyes with larger breaks had a significantly lower reattachment rate compared to eyes with smaller breaks. Vitreous hemorrhage and choroidal detachment had signifi-cant association with anatomic failures. 81.3% of the anatomically successful cases achieved counting fingers or better postoperative vision.
