The effects of posterior subtenon injection of triamcinolone acetonide in patients with intermediate uveitis.

Purpose: Periocular injection of corticosteroids is a common treatment for vision loss in patients with intermediate uveitis. However, this treatment has the potential for serious side effects. We sought to determine the effects of such injections in a series of patients.

Dose-related difference in progression rates of cytomegalovirus retinopathy during foscarnet maintenance therapy. AIDS Clinical Trials Group Protocol 915 Team.

Purpose: A previous dose-ranging study of foscarnet maintenance therapy for cytomegalovirus retinopathy showed a positive relationship between dose and survival but could not confirm a relationship between dose and time to first progression. This retrospective analysis of data from that study was undertaken to determine whether there was a relationship between dose and progression rates, which reflects the amount of retina destroyed when progression occurs.

Methods: Patients were randomly given one of two foscarnet maintenance therapy doses (90 mg/kg of body weight/day [FOS-90 group] or 120 mg/kg of body weight/day [FOS-120 group] after induction therapy.

The progressive outer retinal necrosis syndrome.

The progressive outer retinal necrosis (PORN) syndrome is a recently described clinical variant of necrotizing herpetic retinopathy in patients with the acquired immunodeficiency syndrome (AIDS). It is caused by varicellazoster virus infection of the retina. Its course and clinical features distinguish it from the acute retinal necrosis syndrome and CMV retinopathy.

Progression rates of cytomegalovirus retinopathy in ganciclovir-treated and untreated patients.

Cytomegalovirus retinopathy lesions in patients with the acquired immunodeficiency syndrome may continue to enlarge despite ganciclovir sodium treatment. In an historical cohort study, we used serial, masked retinal photographs to calculate progression rates for 14 ganciclovir-treated patients known to have disease progression and for 17 untreated patients. The median period of evaluation was 23.

Cytomegalovirus retinopathy as the initial manifestation of the acquired immunodeficiency syndrome.

Of 100 consecutive patients with human immunodeficiency virus infection and cytomegalovirus retinopathy, 15 did not have a previous diagnosis of the acquired immunodeficiency syndrome before the ocular infection. All had other HIV-related disorders that would place them in Group IV of the Centers for Disease Control hierarchical classification system for HIV infections. In nine patients, cytomegalovirus retinopathy was the only disorder that fulfilled the Centers for Disease Control criteria for diagnosis of AIDS.

Current practices in the management of ocular toxoplasmosis.

To determine current practices in the management of ocular toxoplasmosis, 72 of 85 uveitis specialists (85%) in the American Uveitis Society completed a detailed questionnaire. Questions involved the indications for beginning treatment, choice of antiparasitic/antimicrobial agents, and experience with treatment of ocular toxoplasmosis in special situations including pregnancy, neonatal infections, and immunocompromised patients. Most of the respondents treat patients whose visual acuity had decreased to worse than 20/200, lesions located in the peripapillary, perifoveal, or maculopapillary bundle regions, and lesions associated with severe vitreous inflammation.

Necrotizing retinopathy after intraocular inoculation of murine cytomegalovirus in immunosuppressed adult mice.

A light microscopic study was done to investigate retinal changes in healthy and immunosuppressed mice after intraocular inoculation of murine cytomegalovirus (MCMV). A 0.01-ml inoculum containing 10(5) plaque-forming units of MCMV was placed behind the lens in 138 4-week-old Swiss Webster mice.
