After successful laser coagulation of subretinal neovascularization, we examined 9 patients to see if laser scar growth (which can be expected according to the literature) is accompanied by an increase in associated scotoma. We used a specially designed visual field program. Laser scars had grown by 23% 107 days after therapy and by 32% after 409 days. The changes in our patients were at the lower range of the data reported in the literature. The increase in the laser scar was statistically significant in just one patient. Mean sensitivity and two further parameters for describing visual fields, which we introduced, all hinted at an improvement in the central visual field, although the laser scars had grown. The mean sensitivity increased by 4.9% and 7.5% after 107 and 409 days, respectively.
在成功进行视网膜下新生血管的激光凝固治疗后，我们检查了9名患者，以观察激光瘢痕生长（根据文献预期会出现）是否伴随着相关暗点的增加。我们使用了专门设计的视野检查程序。治疗后107天激光瘢痕增长了23%，409天后增长了32%。我们患者的变化处于文献报道数据的较低范围。仅1例患者的激光瘢痕增加具有统计学意义。我们引入的平均敏感度以及另外两个描述视野的参数均提示，尽管激光瘢痕有所增长，但中心视野有所改善。107天和409天后，平均敏感度分别提高了4.9%和7.5%。
