Retinal changes following photocoagulation (argon laser, xenon coagulator) were documented biomicroscopically in 31 patients who were studied prospectively for 90 days following treatment. Older photocoagulation scars were examined retrospectively in another 15 patients. The purpose of the study was to evaluate a possible new formation of pigment in the pigment epithelial layer. In most patients new pigment first appeared in the lesions two to three weeks after coagulation. The amount of pigment increased more and more slowly with time, but did not stop until the end of the observation period. Different forms of scar formation were observed, such as severe pigmentation, pigmentation outside the coagulated area, scars with glial components, but also extraretinal effects and effects on the retinal surface far from the coagulated area.
对31例患者进行了前瞻性研究,在光凝治疗(氩激光、氙凝器)后90天内通过生物显微镜记录视网膜变化。另外15例患者对陈旧性光凝瘢痕进行了回顾性检查。本研究的目的是评估色素上皮层中是否可能有新色素形成。大多数患者在凝固后两到三周,新色素首次出现在病变处。色素量随时间增加得越来越慢,但直到观察期结束才停止。观察到不同形式的瘢痕形成,如严重色素沉着、凝固区域外的色素沉着、有神经胶质成分的瘢痕,还有视网膜外效应以及对远离凝固区域的视网膜表面的影响。
