Abstract:
A 59-year-old male patient presented with clinical characteristics of a melanocytoma of the optic disc in the right eye. Using functional tests, such as visual acuity, visual fields, visual evoked potentials (VEP) and imaging procedures (e.g., fundus photography and spectral domain optical coherence tomography) the findings were documented. Best corrected visual acuity was 25/20 in both eyes. Ophthalmoscopy showed a slightly prominent and pigmented tumor in the upper third of the optic disc. Comparing both eyes, an enlarged blind spot and a reduction of VEP were detectable.
