近年来对于光凝治疗脉络膜肿瘤引起了注意和寄于很大希望。Meyer-Schwickerath(1952)治疗一例隆起+4.00D,面积达7PD的肿瘤至今病人仍健康活着。Vogel(1960)曾公布60例脉络膜恶性肿瘤经光凝治疗有33例(55％)临床治愈,惜随访不足。Lund(1962)在眼球摘出前检查34例经光凝治疗者其中11例肿瘤全无改变,若干例肿瘤表面坏死广泛。von Hoffe(1961)证明了类似的事实。治疗效果看来很不一致,令人怀疑治愈者是否真实的脉络膜恶性肿
In recent years, photocoagulation treatment of choroidal tumors caused the attention and send great hope. Meyer-Schwickerath (1952) treats a patient with an elevated + 4.00D area of 7PD so far the patient is still alive. Vogel (1960) has announced that in 60 cases of choroidal malignancies, 33 (55%) were cured by photocoagulation, but their follow-up was inadequate. Lund (1962) examined 34 cases of photocoagulation before treatment, of which 11 had no change and several had extensive necrosis on the surface of the tumor. von Hoffe (1961) proved a similar fact. Treatment seems to be very inconsistent, it is doubt whether the cure is true chorioretinal malignancy
