[Basic directions in enhancing the efficiency of the diagnosis and treatment of ocular tuberculosis].

The paper describes the basic methods for the diagnosis and treatment of ocular tuberculosis, which are based on the studied mechanisms of its pathogenesis. It updates the pathomorphism of the disease, the results of experimental studies dealing with new diagnostic techniques, including an objective estimation of a focal response to tuberculin. The results of studies of ocular tuberculosis in children, as well as the efficacy of the new Russian immunotropic drugs glutoxim and betaleukin are outlined.

[Clinical classification of extrapulmonary tuberculosis].

The authors propose a clinical classification of extrapulmonary tuberculosis, which is based on the standard reporting signs. They give the definitions of classification criteria established in any locations of tuberculous infection: etiology (tuberculosis, BCG infection, tuberculoallergic lesions), the extent and activity of a process with regard to clinical and morphological stages; bacterial isolation with consideration of the drug resistance of Mycobacteria; the nature of complications and sequels, etc. The characterization of local lesion includes the determination of organ-dependent clinical forms of tuberculosis; the type and form of complication; residual and sequels.

[The hemodynamic condition in patients with uveitis of various etiologies].

Our research and comparison of the regional-dynamics condition in patients with ocular tuberculosis (OT) and uveitis of a non-specific etiology revealed the below signs typical of OT: a decreased (by 12% and more) maximum systolic blood-flow velocity (V max) and a decreased minimal diastolic blood-flow velocity (V min--by 53% and more) in the central retinal artery (CRA); as well as a decreased V max (by 34% and more) and a decreased V min (by 72%) in the posterior short ciliary arteries (PSCA). A higher resistance index was registered in the CRA (by 12%) and in the PSCA (by 11%). A higher maximum systolic and minimal diastolic velocity of blood flow in the CRA and PSCA is typical of uveitis of a non-specific etiology.

[Use of Doppler ultrasound study in the diagnosis of ocular tuberculosis].

The paper deals with the study of regional hemodynamics in patients with tuberculous uveitis. The comparative analysis has shown that the most significant microcirculatory changes occur in the central reticular and short posterior ciliary arteries in the presence of specific uveitis. The use of Doppler ultrasound study during tuberculin diagnosis has provided evidence that the most considerable decrease in hemodynamic parameters is detectable in patients with tuberculous uveitis.
