An Isolated Case of Unilateral Macro-Ophthalmia With Resultant Anisometropic Amblyopia in Neurofibromatosis 1.

The most common causes of vision loss in neurofibromatosis 1 (NF1) patients are sequelae from tumors such as optic pathway glioma, plexiform neurofibroma, or secondary glaucoma. Here we report the case of a six-year-old female with anisometropic amblyopia resulting from an isolated unilateral macro-ophthalmia with a known history of NF1. Our patient progressed to light perception vision in the left eye due to a non-neoplastic cause associated with NF1 with at least two years of documented unilateral macro-ophthalmia without any ophthalmology referral or evaluation.
