because one patient only suffers from iris coloboma instead of aniridia, we would like to propose that the primary embryological defect is due to aberrant development of mesoderm 網(wǎng)膜發(fā)育不良,角膜變性,白內(nèi)障及續(xù)發(fā)性青光眼是常見(jiàn)使視力變壞的因素。
method / participants : reporting one case with iris coloboma and a chorioretinal coloboma in his right eye which was noted incidentally during operation for his spontaneous retinal detachment 此病人除了右眼視網(wǎng)膜脈絡(luò)膜呈現(xiàn)缺損,右眼之虹膜亦于鼻下側(cè)方向有鑰匙孔狀缺損。
