Optic neuropathies are a group of pathologies that course with potentially irreversible visual dysfunction. Among compressive causes, optic nerve glioma (GNO) is one of the main ones. Case report: A 12-year-old black school-age female patient seen in February 2020, reported progressive low visual acuity on the right eye (RE) for 6 years. Ectoscopy revealed café au lait spots all over body and hyperchromic nodular lesion in left axilla. Ophthalmologic examination showed acuity of 20/400 in RE and 20/20 in the left eye (LE), relative afferent pupillary defect in RE. At biomicroscopy, irian Lisch nodules. Magnetic resonance imaging (MRI) showed fusiform thickening of intraorbital portion of right optic nerve (ON) with mild enhancement upon gadolinium infusion. Optic neuropathy was secondary to probable GNO. Ophthalmology and neurology management was expectant. Upon return, patient reported intermittent headache and functional and aesthetic discomfort due to axillary lesion, and presented a new MRI with findings similar to the first. Simple retinography showed global pallor in right ON and temporal pallor of left ON. Conclusion: The case presented, in which delay in access to specialized care resulted in blindness, highlights the importance of ophthalmologic screening in NF1. Manifestations resulting from the syndrome, with biopsychosocial repercussions, emphasize importance of multidisciplinary care.
