The ocular abnormalities that occur with this condition include: microphthalmos, microcornea, iridal abnormalities (coloboma, hypoplasia), asymmetric pupil size, shape, or position (dyscoria and/or corectopia), persistent pupillary membranes, lens abnormalities (microphakia, cataract, coloboma, luxation/subluxation), scleral defects (coloboma ...
