The Role of Catecholamines in the Development of Pathological Retina Neovascularization in an Experimental Model of Retinopathy of Prematurity in Rats.

This work is dedicated to proving our hypothesis that catecholamines and their metabolites play a crucial role in the development of retinopathy of prematurity, which leads to progressive uncontrollable vascularization in the retina, leading to blindness. The study was performed in an animal model of retinopathy of prematurity, which was achieved by hyperoxygenation in rats on postnatal days 7, 14, 21, and 30. The content of catecholamines and their metabolites in the retina of rats was determined by high performance liquid chromatography with electrochemical detection.

Spectral filters in low-vision correction.

Coloured filters are used to protect the lens, retina and other ocular tissues against the hazard of light damage and to improve the quality of vision mainly in cases of ocular media opacities. Four types of yellow, amber and orange filters have been designed as tinted glasses, shields and colour covering of spectacles. They were tested on 15 adult patients with partial cataract and on 80 children with congenital pathology (i.

Dexamethasone in the complex treatment of Chlamydial conjunctivitis.

A study was performed on 321 patients with paratrachoma: acute follicular conjunctivitis-189, subacute-132. The first group of patients (108) received 1% Tetracycline ointment 4 to 5 times daily, the second group (103 patients)-1% Tetracycline ointment + 0.1% Dexamethasone eye drops, the third group (110 patients)-Eubetal ointment (tetracycline 0.

A study of the mechanisms of chloroquine retinopathy. I. Chloroquine effect on lipid peroxidation of retina.

The influence of chloroquine on lipid peroxidation in rat and rabbit retinas has been studied. Chloroquine retinopathy is not followed by an increase in lipid peroxidation, and the antioxidant ionol does not prevent the drug effect. Chloroquine has an inhibitory action on induced lipid peroxidation.
