Abstract

An isolated astrocytic hamartoma of the optic nerve head (ONH) is a rare entity that can present without associated systemic manifestations or other retinal findings. We report a unique case involving a 36-year-old Yemeni male who presented with rapid and progressive right eye vision loss. Comprehensive ophthalmic and systemic evaluations were performed. Fundus examination revealed an ONH mass with calcification, while fundus fluorescein angiography (FFA) demonstrated late leakage from the optic disc lesion. B-scan ultrasonography and optical coherence tomography (OCT) further characterized the ONH calcifications. The diagnosis was made presumptively based on clinical findings and exclusion of other conditions, including tuberous sclerosis complex (TSC). Informed consent was obtained from the patient prior to documenting this case.
