The authors studied the effectiveness of laserpexy versus cryopexy for treatment of acute retinopathy of prematurity.
Seventy-six eyes in 41 patients were treated for acute retinopathy of prematurity from January 1991 to April 1994.
Fifty-six eyes in 30 patients had zone 2 disease. Of these 30 patients, 11 received laser treatment and 20 received cryopexy treatment; there was at least one anatomically successful eye in each patient. Twenty eyes in ten patients had zone 1 disease. Seven patients had bilateral laser treatment. Three patients had bilateral cryopexy. In seven eyes with zone 1 disease, five were treated successfully with laser. None of the three eyes with zone 1 disease treated with cryopexy were successful.
Laserpexy and cryopexy are of equal efficacy in treating zone 2 disease. There is a tendency that suggests that laserpexy is more effective than cryopexy in treating zone 1 disease. Diode and argon lasers are of equal efficacy in treating zone 1 disease.
作者研究了激光光凝术与冷冻疗法治疗早产儿急性视网膜病变的有效性。
1991年1月至1994年4月，对41例患者的76只眼睛进行了早产儿急性视网膜病变的治疗。
30例患者的56只眼睛患有2区疾病。在这30例患者中，11例接受了激光治疗，20例接受了冷冻治疗；每位患者至少有一只眼睛在解剖学上获得成功。10例患者的20只眼睛患有1区疾病。7例患者接受了双侧激光治疗。3例患者接受了双侧冷冻治疗。在患有1区疾病的7只眼睛中，5只通过激光治疗成功。接受冷冻治疗的3只患有1区疾病的眼睛均未成功。
激光光凝术和冷冻疗法在治疗2区疾病方面疗效相当。有迹象表明，激光光凝术在治疗1区疾病方面比冷冻疗法更有效。二极管激光和氩激光在治疗1区疾病方面疗效相当。
