Twenty-nine cats with naturally occurring cryptococcosis were evaluated prior to commencing oral fluconazole therapy (25-100 mg every 12 h). Affected cats ranged from 2 to 15 years-of-age. Male cats (19; 66%) and Siamese cats (5; 21%) appeared to be over-represented in comparison to the hospital's cat population. Mycotic rhinitis was observed in 24 (83%) of the cases, although nasal cavity involvement was subtle in four animals. Disease of the skin and subcutaneous tissues was present in 15 cases (52%) and amongst these the nasal plane (seven cats) and bridge of the nose (seven cats) were most commonly involved. Primary infection of the central nervous system was not encountered, although one cat developed meningoencephalitis and optic neuritis as a sequel to longstanding nasal cavity disease. Antibodies against the feline immunodeficiency virus (FIV) were detected in eight cats (28%), and these cats tended to have advanced and/or disseminated disease. There was a tendency for cats to develop cryptococcosis during the Australian summer. Organisms were cultured from 27 cases. Cryptococcus neoformans var. neoformans was isolated from 21 cats, while C. neoformans var. gattii was identified in the remaining six. The response to oral fluconazole was excellent in this series, which included many cats with advanced, longstanding or disseminated disease. The fungal infection resolved in all but one advanced case which died after only 4 days of therapy. A dose of 50 mg per cat, given every 12 h, produced a consistently good response without side effects. Lower doses were effective in some cases, while 100 mg every 12 h was required to control the infection in one cat. Serum fluconazole levels obtained during chronic dosing (50 +/- 18 mg l-1, mean +/- SD; 50 mg per cat every 12 h) were highly variable (range 15-80 mg l-1). Concurrent FIV infection did not impart an unfavourable prognosis, although affected cats often required prolonged courses of therapy.

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.

We reviewed the neuro-ophthalmic findings in 177 subjects with the acquired immunodeficiency syndrome (AIDS) or AIDS-related complex who underwent an eye examination in one center from January 1984 to May 1989. The findings included ocular motor nerve palsies (five cases), papilledema (two cases), cytomegalovirus optic neuritis (two cases), cortical blindness (one case), conjugate gaze palsy (one case), and altitudinal visual field defect (one case). These findings were attributed to central nervous system toxoplasmosis (four cases) or lymphoma (one case), cryptococcal meningitis (two cases), systemic cytomegalovirus infections (two cases), and herpes simplex encephalitis (one case). Of 177 patients, 61 patients were tested for syphilis. Twenty-six patients had positive rapid plasma reagin titers, and 28 had positive fluorescent treponemal antibody-absorbed tests. Human immunodeficiency virus-infected individuals need to be screened routinely for syphilis.

The management of opportunistic infections is a significant problem in acquired immunodeficiency syndrome (AIDS) and the development of more effective chemotherapeutic agents is needed. We present the ocular manifestations of an AIDS-like disease in rhesus monkeys experimentally infected with simian immunodeficiency virus (SIV) at the Delta Regional Primate Research Center. These findings consisted of rubeosis in the anterior segment and retinitis, optic neuritis, choroiditis and panophthalmitis in the posterior segment of the eye. Investigation of the retinas by electron microscopy revealed SIV in both eyes of one animal and a herpes virus in two animals. Serology confirmed cytomegalovirus (CMV) as the likely agent. This primate model will prove useful for both further investigations of the possible interaction between immunosuppressive lentiviruses and CMV in ocular disease and antiviral drug testing.

Nine patients with active ocular or optic nerve involvement by syphilis who also had concurrent human immunodeficiency virus type-1 (HIV-1) infection are described. The ocular manifestations of syphilis led to the discovery of HIV-1 seropositivity in four of nine cases. Fifteen eyes were affected. Ocular manifestations were: iridocyclitis in three eyes, vitreitis in one eye, retinitis or neuroretinitis in five eyes, papillitis in two eyes, optic perineuritis in two eyes, and retrobulbar optic neuritis in two eyes. Three patients diagnosed with acquired immune deficiency syndrome (AIDS) had the worst initial visual acuities. Six of nine patients had evidence of concomitant central nervous syndrome (CNS) involvement with syphilis. Benzathine penicillin was administered intramuscularly to three patients. All three had relapses. Seven of nine patients treated intravenously with high-dose penicillin had dramatic responses to therapy with improvement in vision and serologies and no evidence of relapse. Regimens accepted for the treatment of neurosyphilis appear to be adequate for the treatment of ocular syphilis in HIV-1-infected patients though further long-term follow-up will be required.

We have tested sera from patients with multiple sclerosis, matched controls, and those with other neurological diseases, as well as sera from patients with the acquired immunodeficiency syndrome and controls and patients with tropical spastic paraparesis (TSP) and controls for antibody to human T-lymphotropic virus type I (HTLV-I), HTLV-II, human immunodeficiency virus (HIV), simian T-lymphotropic virus type III, or simian retrovirus type I by immunofluorescent activity test, and for HTLV-I and HIV by the ELISA method. Sera from patients with multiple sclerosis and matched controls, and from patients with optic neuritis and Parkinson's or other neuromuscular diseases did not have antibody to any of the retroviruses tested. Specimens from TSP patients and some controls contained HTLV-I antibody. We conclude from our study that only TSP patients had serological evidence of infection with one of the retroviruses studied.

We diagnosed ocular syphilis in three homosexual men infected with human immunodeficiency virus (HIV). Ocular inflammation included uveitis, optic neuritis, and retinitis. Dermatologic and central nervous system manifestations of secondary syphilis were also present. The history of homosexuality was difficult to obtain. Concomitant infection with HIV may alter the course of syphilis, obscure the diagnosis, and impair the response to therapy.

A 37-year-old man with bilateral optic neuropathy who recovered on steroid treatment is described. He was subsequently found to be human immunodeficiency virus 1 (HIV-1) positive prior to the onset of his visual symptoms, and no other cause of his optic neuropathy could be found. There is some evidence that HIV itself may be a cause of symptomatic optic neuropathy. A spontaneously relapsing and remitting multiple sclerosis-like syndrome has previously been described in HIV-positive patients, and this may present with optic neuritis. A chronic optic neuritis in HIV-positive patients that is not usually symptomatically important has also been described. We review the literature related to these topics and our patient.

This case is about a unilateral retrobulbar optic neuritis, as rare and first sing of HIV infection. A young woman had came at Eye Clinic because suddenly she lost her sight on the right eye completely. At the visual field, we found anopsia, but at the stereoscopic fundus examination the situation was almost normal. After complete clinical examination we conclude that she is immunodeficiency person, HIV-positive, with clinical manifestation retrobulbar neuritis and with skin manifestation varicella zoster infection in region of the left arm.
