[Specular microscopy in the diagnosis of the iridocorneal endothelial syndrome]. / Apport de la microscopie spéculaire dans le diagnostic du syndrome endothélial irido-cornéen.

Irido-corneal endothelial syndrome regroups three disorders including: endotheliopathy, peripheral anterior synechiae and iris changes. According to the aspect of these abnormalities, three syndromes are described: essential iris atrophy, Chandler's syndrome and iris naevus (Cogan-Reese) syndrome. Endothelial changes studied by specular microscopy are typical: in early stages, a rounding off cell angles and intracellular blackout areas can be seen; in former stages, black out areas increase and there is a disruption of the regular mosaic. These features are a major point for differential diagnosis. We present six cases reports among which three where effectively diagnosed as iridocorneal endothelial syndrome and three were not.
