作者用氩离子激光器治疗翼状胬肉26例29眼,计初期7例8眼,轻度10例11眼,重度5例5眼,复发4例5眼;轻、重度及复发型者按外观又可分为膜型2例2眼,普通型12例13眼,肉芽型5例6眼。操作方法:先用Benoxinate点眼麻醉(2～3分钟内点眼5～7次),后行光凝:对准胬肉体部以血管为主作光凝中断血流,此时如颈部血管怒张,亦行光凝。根据胬肉的程度不同,光凝条件也有所差异,其范围是:压强200～400毫瓦,时间0.2～10秒,直径200微米。每次凝固
The authors used argon ion laser treatment of pterygium in 26 patients and 29 eyes, initially 7 cases in 8 eyes, 10 cases in 11 eyes, 5 cases in 5 cases and 4 cases in 5 cases. The patients with mild, moderate and recurrent Can be divided into two cases of membrane type 2, 13 cases of 12 cases of ordinary type, 5 cases of granulation 6 cases. Method of operation: first with Benoxinate eye anesthesia (2 to 3 minutes eye 5 to 7 times), after the photocoagulation: the main body of the pterygium to the main blood vessels for photocoagulation interruption of blood flow, this time as the neck vascular distention , Also act light condensate. Depending on the degree of pterygium, there are differences in photocoagulation conditions in the range of 200 to 400 milliwatts of pressure, 0.2 to 10 seconds and 200 microns in diameter.
