Abstract
PURPOSE
To report a case of unilateral Iridocorneal endothelial (ICE) syndrome- Progressive iris atrophy (PIA) with an overlapping chronic angle closure glaucoma (CACG) and to highlight the effect of bilateral Laser peripheral iridotomy (LPI) in such a co-occurrence.
CASE DESCRIPTION
A patient presented to us with bilateral gradual painless progressive diminution of vision. Both eyes (BE) had a clear cornea, shallow peripheral anterior chamber depth, grade 2 nuclear sclerosis, raised intraocular pressure and glaucomatous optic neuropathy. In addition, the Left eye (LE) had an irregular anterior chamber, peripheral anterior synechiae (PAS) extending to cornea, patchy iris atrophy, subtle corectopia and a low endothelial cell count on specular microscopy. Indentation gonioscopy led to the diagnoses of CACG BE with ICE syndrome- PIA LE. LPI was performed bilaterally. On Anterior Segment Optical Coherence Tomography (ASOCT), there was evident widening of the angle away from PAS in the Right eye as well as in the LE with PIA post LPI.
CONCLUSION
This is a unique case of unilateral PIA with an associated CACG in BE. It is the first case demonstrating the effect of bilateral LPI in such a case scenario. Though not indicated in ICE syndrome, LPI did show short term evidence of significant widening of the angle away from areas of PAS even in the eye with PIA having a limited high PAS and a concurrent primary (chronic) angle closure disease.
