激光在眼科的应用史并不长,但因其单色性、方向性好,能量集中,进入眼内无色差,光凝点可准确地落在病灶上,而且曝光时间短,操作简便,病人无痛苦,故其应用已展现良好的前景。一、激光治疗眼底疾病 (一)封闭视网膜裂孔:因视网膜变性和玻璃体条索牵拉可引起视网膜裂孔,液化玻璃体通过裂孔进入视网膜下间隙,使视网膜脱离,严重破坏视力。封闭 The history of application of laser in ophthalmology is not long, but because of its monochromaticity, good directivity, energy concentration, no color difference into the eye, photocoagulation point can accurately fall on the lesion, and the exposure time is short, easy to operate, the patient No pain, so its application has shown good prospects. First, the laser treatment of retinal diseases (A) closed retinal hiatus: Due to retinal degeneration and vitreous cords traction can cause retinal tears, liquefied vitreous into the subretinal space through the hiatus, the retinal detachment, severe damage to vision. Closed
