OCT/LCT monitoring of drug action on the structure of the human cornea in vivo

The effect of anti-glaucoma medicinal prepaprations Timolol-AKOS and Cosopt on the structure components of human eye cornea are studied. The eye drops Timolol-AKOS 0.5% and Cosopt were used as the object of study. 10 voluntary patients of the Eye Disease Clinic aged from 70 to 75 suffering from glaucoma took part in the studies. The study of cornea in vivo was carried out using the methods of laser scanning confocal tomography (LCT) and optical coherence tomography (OCT) before the application of drugs and at different time moments after the application. The eye cornea thickness values measured using the OCT at the initial moment of time and at different times after the application of the medicinal preparations are presented. From the LCT data the density and the mean diameter of the cornea epithelial cells was calculated. As a result of the complex studies carried out, it was shown that the Timolol-AKOS medication causes the swelling of the cornea within the limits of 1-5%. Under the use of Cosopt medication the cornea dehydration was observed.
