A case of acquired posterior keratoconus is presented. As in developmental cases the vision was moderately reduced and the condition was not progressive. Posterior keratoconus is usually developmental in origin, but trauma has been implicated in some cases.
本文报告一例获得性后圆锥角膜病例。与发育性病例一样，视力有中度下降，且病情无进展。后圆锥角膜通常起源于发育异常，但在某些病例中也与外伤有关。
