Visual functions in patients with cytomegalovirus uveitis and HIV infection

BACKGROUND: Cytomegalovirus damage to the eye is the leading cause of loss of visual functions associated with HIV. Effective treatment of HIV-infected patients has changed the understanding of the clinical picture of cytomegalovirus uveitis (CMV-uveitis). 
AIM: The aim of the work is to determine the prevalence, the structure of clinical forms and to evaluate visual functions in HIV-infected patients with CMV-uveitis. 
MATERIALS AND METHODS: The study group consisted of 66 HIV-infected patients with CMV-uveitis (97 eyes), of which there were 27 men (40.9%), 39 women (59.1%). The average age was 39.6 3.91 years. All patients had stage 4B of HIV infection according to V.V. Pokrovskys classification (2006). During the work, visometry, perimetry, biomicroscopy, ophthalmoscopy were used. 
RESULTS: The main form of the disease is chorioretinitis, diffuse and generalized forms of the disease are diagnosed in 68.0% of cases. In predicting visual acuity, the leading regression criterion was the clinical form of the disease. 
CONCLUSIONS: Diffuse and generalized forms of the disease prevailed in clinical practice. Localization of the chorioretinal process of a predominantly diffuse nature predetermined visual acuity, which in more than a third of cases met the criteria for blindness according to the WHO classification (1977).
