Morse等(1980)曾估计10～34%有闪光及漂浮物的眼会有视网膜裂孔。如不治疗,33—46%的病例可发生视网膜脱离。由于早期发现较困难,作者试图就这些症状与体征之间的关系来确定视网膜裂孔危险率高的病例。本文包括589例(男220例,女369例)主诉闪光及漂浮物的病例。其中123例40岁以下,52例70岁以上。每一病例均作间接眼底镜及巩膜压陷检查;大多数病例尚作三面镜检查。除外曾作眼部手术或有损伤史以及并发性眼病如糖尿病性视 Morse et al. (1980) have estimated that 10 to 34% of eyes with flares and drifts will have retinal tears. Without treatment, retinal detachment can occur in 33-46% of cases. Due to the difficulty of early detection, the authors attempted to determine the presence of a high risk of retinal breaks on the basis of the relationship between these symptoms and signs. This article includes 589 cases (220 males and 369 females) who complained of flash and floating debris. Of these, 123 were under 40 and 52 were over 70 years of age. Indirect ophthalmoscopy and scleral buckling were performed in each case; in most cases, three-mirror examination was performed. Except for the history of eye surgery or injury and concomitant eye diseases such as diabetic
