To assess the effectiveness of low power transpupillary thermotherapy (TTT) for choroidal neovascularization (CNV).
We performed TTT on 55 eyes of 55 patients with subretinal CNV between April 2001 and December 2002, and observed them after therapy for more than 6 months. The laser power ranged from 80 to 320 mW when the spot size was 3 mm. We evaluated visual acuity, subretinal fluid (SRF), and CNV size.
Visual acuity improved by 2 lines or more in 16 eyes (29%), was unchanged in 19 eyes (35%), and decreased in 20 eyes (36%). SRF decreased in 30 eyes (54%), was unchanged in 13 eyes (24%), and increased in 12 eyes (22%). CNV diminished in 33 eyes (60%), was unchanged in 10 eyes (18%), and became enlarged in 12 eyes (22%).
Low power TTT can be an effective treatment for subgroups of patients with subfoveal CNV.
评估低功率经瞳孔温热疗法（TTT）治疗脉络膜新生血管（CNV）的有效性。
2001年4月至2002年12月期间，我们对55例视网膜下CNV患者的55只眼进行了TTT治疗，并在治疗后观察了6个月以上。光斑大小为3mm时，激光功率范围为80至320mW。我们评估了视力、视网膜下液（SRF）和CNV大小。
16只眼（29%）视力提高2行或更多，19只眼（35%）视力不变，20只眼（36%）视力下降。30只眼（54%）的SRF减少，13只眼（24%）不变，12只眼（22%）增加。33只眼（60%）的CNV缩小，10只眼（18%）不变，12只眼（22%）扩大。
低功率TTT可能是治疗黄斑下CNV患者亚组的有效方法。
