Abstract

A 2-day-old Hispanic boy was transferred to us with concerns of a small left eye. The pregnancy was uncomplicated, and both parents are healthy. Examination showed a left orbit that appeared to be empty with conjunctival tissue. The right eye had a 7 mm clear cornea, and retinal exam showed areas of thin or absent tissue and no visible optic nerve. MRI revealed a hypoplastic left orbit with an orbital cyst. The anterior-posterior diameter of the right globe was 14 mm and the left globe was 4 mm. Genetic microanalysis showed genetic abnormalities (845 kb gain) on chromosome 14 at q32.33. A diagnosis of bilateral microphthalmia with an orbital cyst was made. This is an isolated case of bilateral microphthalmia possibly associated with 14q32-33.
