The refractive error in 15 eyes with threshold retinopathy of prematurity treated with diode laser photocoagulation was compared with 25 eyes with the same disease severity treated by cryotherapy. Myopia was present in 40% (six eyes) of the first group ranging from -1.50 to -3.50 dioptres; while 92% (23 eyes) showed myopia which ranged from -0.50 to -8.00 dioptres in the cryotherapy group. Sixty per cent (nine eyes) were hypermetropic at less than +3.0 dioptres in the laser group, while only 8% (two eyes) of the cryotherapy group showed hypermetropia. There was no significant difference in astigmatism between the two groups. Eyes with threshold disease treated with diode laser photocoagulation developed significantly less myopia than those treated with cryotherapy (p = 0.0006, two tailed value).
将接受二极管激光光凝治疗的15例阈值ROP患儿的15只眼屈光不正情况,与接受冷冻疗法治疗的25例相同疾病严重程度患儿的25只眼进行比较。第一组中40%(6只眼)出现近视,屈光度在-1.50至-3.50之间;而冷冻治疗组中92%(23只眼)出现近视,屈光度在-0.50至-8.00之间。激光治疗组中60%(9只眼)为远视,屈光度小于+3.0,而冷冻治疗组中只有8%(2只眼)为远视。两组散光情况无显著差异。接受二极管激光光凝治疗的阈值ROP患儿眼近视程度明显低于接受冷冻治疗的患儿眼(p = 0.0006,双侧值)。
