Endoscopic optic nerve decompression in a patient with fibrous dysplasia

Purpose: To report recovering vision in a patient with fibrous dysplasia involving the sphenoid bone bilaterally after endoscopie optic nerve decompression. We will present our technique of endoscopie optic nerve decompression, together with visual fields, radiological, and histopathologic presentation of the case. Method: Endoscopie optic nerve decompression was performed through a combined approach. A biopsy of the lesion was performed for histopathologic evaluation. Results: Visual acuity improved from counting fingers to 20/20 with complete recovery of the visual field defect. Conclusion: Non-traumatic blindness caused by fibroid dysplasia can be reversed by endoscopie optic nerve decompression.
