[Syphilitic uveitis and human immunodeficiency virus infection].

Ocular syphilis is rare in human immunodeficiency virus infected individuals. We think that syphilis should be considered in evaluating such patients presenting with uveitis. Most often, ocular syphilis includes retinitis associated with anterior or posterior uveitis, sometimes with optic neuritis. Concurrent neurosyphilis is frequent and may be more aggressive; it may progress more rapidly and cause more atypical signs than in patients without human immunodeficiency virus infection. This suggests the need for lumbar puncture in the evaluation of coinfected patients. The standard serological tests for syphilis (in blood and cerebrospinal fluid) may be nonreactive in human immunodeficiency virus seropositive patients. It may be because of the alteration of immunologic response of such patients. All coinfected patients with human immunodeficiency virus and syphilis should be treated with high-dose intravenous penicillin G sodium as recommended for neurosyphilis. We describe two human immunodeficiency virus infected patients with ocular syphilis and neurosyphilis.

[Cytomegalovirus retinitis in AIDS. Treatment with intravitreal injections of ganciclovir].

Cytomegalovirus (CMV) retinitis is the most frequent ocular infection in AIDS, and it is responsible for blindness. Intravitreal injections of ganciclovir in doses of 400 g have been tried in patients who could not tolerate any systemic treatment. Induction therapy consists of 2 injections per week, followed by maintenance therapy with 1 injection per week. The present study involved 17 patients. Twenty-three induction courses could be evaluated; all had a favourable response with an average of 6 injections per eye. Seventeen maintenance courses were evaluated, with a mean of 5 injections per eye. There was no relapse in 10 eyes (70 percent) at 48 days. There was no evidence of toxicity from repeated intravitreal injections: no cataract, retinal detachment or endophthalmitis was observed with a total of 231 injections. Intravitreal ganciclovir appears to be an effective local treatment of CMV retinitis in AIDS patients when systemic therapy cannot be used.

[Rupture of the hemato-ocular barrier, studied by fluorophotometry, in uveal melanoma patients. Preliminary results].

PURPOSE: To evaluate the use of intravenous vitreous fluorophotometry in assessment of the blood-aqueous barrier in eyes with uveal melanoma. METHOD: Vitreous fluorophotometry was performed before treatment in 14 patients with uveal melanoma. Both eyes of patients were examined, and fifteen control healthy patients were examined between November 1996 and December 1996 at the department of ophthalmology of Bicêtre hospital. RESULTS: Tumors with height > 6 mm and serous retinal detachments were accompanied by marked alterations of the blood-aqueous barrier, vitreous fluorophotometry showed diffusion of dye in posterior, mid and anterior vitreous: 2.99 ng/ml in the posterior vitreous and 5.20 ng/ml in the anterior vitreous. The posterior vitreous fluorescence at 60 minutes in the control eyes was 1.43 ng/ml and 1.30 ng/ml in the anterior vitreous. Diffusion of dye was present in the posterior vitreous in patients with tumor height less than 6 mm: 2.38 ng/ml (1.43 ng/ml in control eyes) at 60 minutes. CONCLUSIONS: Fluorophotometry provides a method for the assessment of the blood-aqueous ocular barrier in eyes with choroidal melanoma.
