Iridocorneal endothelial syndrome: a mysterious question

A 43-year-old healthy woman complained for progressive visual loss over 5 years OD with greyish reflect of his eye. Her ophtalmological and medical history was unremarkable. Visual acuity was light perception OD and 6/6 OS. Adnexal examination and pupillary reflex were normal. She had ocular hypertension estimated at 52 mmHg by Goldmann applanation tonometry. Gonioscopy showed angle closure with multiple peripheral synechiae. On slit-lamp examination we noticed a tear break up time test at 04 seconds with diffuse punctuate keratitis, corneal hypoesthesia, diffuse corneal edema, dyscoria, polycoria with iris atrophy and holes. Endothelial evaluation with high magnification showed "hammered silver" appearance that was difficult to document at slit lamp photography. The crystalline lens was clear and fundus ophtalmoscopy was inaccessible. This constellation of signs was consistent with Iridocorneal Endothelial (ICE) syndrome. The fellow eye was normal.
