The author describes the macroscopical, microscopical and ultrastructural features of a peculiar form of snail track degeneration, which was found in 3 eyes with absolute glaucoma. The snowflakes are concentrated to scattered patches in an extensive frosted area of the peripheral retina. The glittering points consist of neutral fat in a gliotic and atrophic retina. Electron microscopy examination shows fat droplets within the astrocytes and Müller cells. These findings are believed to be the expression of a "in situ break down" of a very slowly atrophying retina by the macroglia.
作者描述了一种特殊形式的蜗牛迹样变性的宏观、微观和超微结构特征，该病变见于3只绝对期青光眼患眼中。雪花状病变集中于周边视网膜广泛的磨砂样区域内的散在斑块处。闪光点由胶质化和萎缩性视网膜中的中性脂肪构成。电子显微镜检查显示星形胶质细胞和米勒细胞内有脂肪滴。这些发现被认为是大胶质细胞对非常缓慢萎缩的视网膜进行“原位分解”的表现。
