视网膜裂孔是网脱的基础,裂孔的产生又与网膜本身变性及玻璃体脱离时的牵引关系密切。上述变化多见于眼底周边部。网脱的发生与周边部病变的性质和程度,网膜与网膜色素上皮之间粘着力的强弱以及玻璃体条索牵引力的大小息息相关。用双目检眼镜结合巩膜压迫器或以裂隙灯显微镜三面镜联合压陷对网脱眼的赤道部、锯齿缘及睫状体扁平部进行详细的检查、以利于网脱的早期诊断和有针对性的治疗。
Retinal hiatus is the basis of net detachment, and the occurrence of hiatus is closely related to the degeneration of the omentum itself and traction when vitreous detachment. More common in the peripheral changes in the fundus. The incidence of nephrectomy is related to the nature and extent of lesions in the peripheral part, the strength of adhesion between the omentum and the retinal pigment epithelium, and the size of the vitreous traction. With binocular ophthalmoscope with scleral buckler or slit lamp microscope with three-mirror combined with the collapse of the eye of the equator, the serrated edge and the ciliary body flat to conduct a detailed examination in order to facilitate the early diagnosis of net off and targeted Sexual treatment.
