视网膜裂孔的发生率虽为5.8～13.7%,而网膜脱离的发生率只有1/1～2万。临床中裂孔与网膜脱离之比例大约为83:1。早在六十年前(1920年)Gonin 就指出封闭网膜裂孔是治疗本病的关键所在,这一原则至今未变。可见裂孔在网脱发病中确占有重要地位,但不是唯一因素。在裂孔存在的情况下,网脱的发生可以视为玻璃体的牵引力大于网膜神经上皮层与色素上皮层间粘着力的结果。尽管有一些网脱在发生脱离之前并无明显的眼底改变,但大多数既有网膜上的改变又有玻璃体的变化,此类病态则属逐渐形成和发展
Although the incidence of retinal tears is 5.8 ~ 13.7%, while the incidence of retinal detachment only 1/1 to 2 million. Clinically, the ratio of retinal detachment and retinal detachment is about 83: 1. As early as sixty years ago (1920) Gonin pointed out that the closure of the omentum is the key to the treatment of this disease, the principle has not changed. Holes can be seen in the net hair loss disease does occupy an important position, but not the only factor. In the presence of a tear hole, the occurrence of net detachment can be considered as a result of the traction of the vitreous being greater than the adhesion between the retinal neuroepithelium and the pigment epithelium. Although there are some net off in the occurrence of detachment before there is no significant change in the fundus, but both the changes in both the omentum and vitreous changes, such illness is a gradual formation and development
