Abstract:
An HIV-positive man with subacute syphilitic meningitis developed severe bilateral visual loss from optic neuritis. His visual acuity improved remarkably within 24 hours after single posterior sub-Tenon's injections of triamcinolone (Kenalog) were given. Periocular steroid injections should be considered as an adjunctive treatment of syphilitic optic neuritis.
