The contralateral eye in the iridocorneal endothelial (ICE) syndrome.
Examination of six cases of iridocorneal endothelial (ICE) syndrome revealed that all the patients had subclinical abnormalities in the fellow eye. Of the six, four patients had iris transillumination, four patients had significantly decreased outflow facility but without elevation of intraocular pressure, and all patients had corneal endothelial changes as noted by specular microscopy. The asymmetric rather than unilateral involvement and the similar histopathology to posterior polymorphous dystrophy suggested that these two diseases may share a common pathogenesis. The occurrence of features of Rieger's syndrome and Axenfeld's anomaly in association with posterior polymorphous dystrophy suggested the hypothesis that all these diseases may be characterized by abnormalities of tissues derived from neural crest cells. A unifying hypothesis is presented to explain this group of diseases involving the endothelial cells lining the anterior chamber, namely corneal and trabecular meshwork endothelium, anterior iris stroma and iris melanophores.
