BACKGROUND Neurofibromatosis type 1 (NF1) is a common autosomal dominant genetic disorder with an extremely variable phenotype. In childhood NF1 can be associated with optic glioma and central precocious puberty; the latter is more common when the optic chiasm is affected. The mutational spectrum of the NF1 gene is wide and complex; R681X is a rare severe mutation of the NF1 gene known to cause...

An experimental model for acute allergic optic neuritis was produced in adult strain 13 guinea pigs by sensitization with isogenic spinal cord emulsion in complete Freund's adjuvant. These animals exhibited two distinct clinical patterns: (1) "retrobulbar optic neuritis," with a diminished pupillary response to light despite a normal fundus, and (2) "neuroretinitis," with a diminished pupillary...

The results of computed tomography (CT) of the orbits and brain of 29 patients with neurofibromatosis were reviewed to determine the contribution of CT scanning to the diagnosis of this disorder. In the presence of orbital symptoms, CT confirmed the presence of suspected lesions such as optic nerve gliomas, demonstrated asymptomatic and atypical lesions, and displayed concomitant intracranial i...
