Purpose: To evaluate the frequency of Von Recklinghausen neurofibromatosis type 1 (NF1) ocular abnormalities.
Methods: A retrospective study was conducted in 11 patients during two years.
Results: We found Lisch nodules in 4 cases associated to conjunctival lesion in one case and to retinal hamartoma in another case. In two cases, we found an eyelid neurofibroma. One patient had orbital fibrosis dysplasia. Ocular disease revealed the NF1 in 4 cases, the tumoral exophtalmia in two cases.
Conclusion: The ocular manifestations of Von Recklinghausen disease are frequent and can reveal the disease. Ophthalmologic examination must always be performed if Von Recklinghausen is suspected.
