糖尿病性網膜症,静脈閉塞症,網膜裂孔にみられた後部硝子体索状物の切開のためNd:YAGレーザーを実施した13例を検討した.13例中4例は完全に切開された.7例は部分的に成功し,不成功は2例であった.合併症として8例(61.5%)に網膜前あるいは硝子体出血を認めた.1例に比較的大量の出血を見た.Nd:YAGレーザーは孤立性,無血管性で,網膜から離れているものに慎重に実施する必要がある.しかし装置,コンタクト・レンズの改良,治療手技の改良などにより,適応範囲は今後拡大すると思われる.
We attempted to dissect vitreous strands or membranes in 13 eyes with Q-switched Nd-YAG laser. The series included diabetic retinopathy 10 eyes, branch retinal vein occlusion 2 eyes and retinal tear 1 eye. The aim of treatment was torelieve traction retinal detachment 7 eyes, to pre-vent vitreous hemorrhage 5 eyes, and to remove membrane anterior to the macula 2 eyes.
The treatment was successful in 4 eyes, partially successful in 7 and unsuccessful in 2. Complications occurred in 8 eyes, including vitreous hemorrhage from neovascular tissue in the strands or from vessels in the retina or choroid. Nd-YAG laser vitreolysis was thus useful in selected cases with vitreous strands.
