To examine the foveal cone photopigment kinetics in two patients with commotio retinae of the posterior pole (Berlin edema).
A noninvasive technique, called fundus reflection densitometry, was used to provide a measure of the amount of visual photopigment at the foveal area and the time constant of photopigment regeneration.
Strongly impaired foveal cone photopigment kinetics were found in two patients during the acute stage of commotio retinae. Complete recovery occurred within 3 months in both patients.
Retinal opacification in Berlin edema is accompanied by a traumatic lesion at the level of the photoreceptor-retinal pigment epithelium (RPE) complex. These results support recent histopathologic data on commotio retinae, which revealed moderate photoreceptor outer segment disruption and retinal pigment epithelium damage. According to our data, such damage might be reversible.
研究两名患有后极部视网膜震荡（柏林水肿）患者的中央凹视锥细胞光色素动力学。
采用一种名为眼底反射密度测定法的非侵入性技术，来测量中央凹区域视觉光色素的量以及光色素再生的时间常数。
在两名视网膜震荡急性期患者中发现中央凹视锥细胞光色素动力学严重受损。两名患者均在3个月内完全恢复。
柏林水肿中的视网膜混浊伴有光感受器 - 视网膜色素上皮（RPE）复合体水平的创伤性病变。这些结果支持了最近关于视网膜震荡的组织病理学数据，该数据显示光感受器外段有中度破坏以及视网膜色素上皮损伤。根据我们的数据，这种损伤可能是可逆的。
