Abstract
The authors report an HIV-seropositive patient with syphilitic perioptic neuritis as an initial and isolated manifestation of neurosyphilis. Cerebrospinal fluid was within normal limits. Visual evoked potentials (VEP's) showed a marked delay to medium spatial frequency grating stimuli (4.6 cycles per degree) but not to a coarse stimulus (2.3 cycles per degree) suggesting selective vulnerability of optic nerve fibers. The VEP normalized after treatment corresponding with improvement of the perioptic neuritis.
