急性後部硝子体剥離の合併症

Complications of acute posterior vitreous detach-ment

　飛蚊症や光視症の自覚後3か月以内に眼科を受診し，後部硝子体剥離と診断された156人（36〜84歳，平均61歳），156眼を対象として，急性後部硝子体剥離に伴う合併症の出現頻度を性，年齢，屈折度との観点から検討した。合併症として網膜裂孔（15％），硝子体出血（13％），網膜出血（5％），後天性網膜分離症（3％），類嚢胞黄斑浮腫（1％），網膜血管牽引（1％）がみられた。飛蚊症や光視症を自覚した60歳未満の男性の後部硝子体剥離例では，その約半数になんらかの網膜・硝子体合併症が認められた。

We assessed the frequency of complications as-sociated with acute symptomatic posterior vitreous detachment in terms of sex, age and refraction. The study involved 156 eyes, 156 patients, examined within 3 months after onset of symptoms including floaters and flashing light. The age ranged from 36 to 84 years, average 61 years. There were 53 malesand 103 females. Major complications in the 156 eyes included retinal tear 15%, vitreous hemor-rhage 13%, retinal hemorrhage 5%, acquired retinoschisis 3%, cystoid macular edema 1% and avulsed vessels 1%. These complications were pre-sent in more than half of males who were under 60 years of age and who noted floaters or flashing light consequent to posterior vitreous detachment.
