Depth perception problems

Submitted by Maxwell Stem, MD - Pennsylvania Retina Specialists, PC

22 month old with a h/o autism spectrum disorder, lipomyelomeningocele, failure to thrive, and intellectual disability born at 34 weeks gestational age referred for "depth perception problems"

DIAGNOSIS: Familial Exudative Vitreoretinopathy (FEVR)

The patient presented with profound peripheral retinal ischemia OD > OS and a retinal fold in the right eye.  The DDx included ROP, FEVR, Coats Disease, and Norrie Disease. He underwent genetic testing which revealed a mutation in the CTNNB1 gene.  This gene encodes a protein called β-catenin, which plays a role in Wnt signaling.  Abnormalities in the Wnt signaling pathway are associated with FEVR.

The patient underwent peripheral pan-retinal photocoagulation to the areas of ischemic retina in both eyes.
