Detailed analysis of copper compounds migration in the corneal stroma are presented. The biochemical conditions of the middle periphery of the cornea is found to inhibit copper ions movement to the center in patients with keratoconus due to increased tear alkalinity. Low concentration of dichlorocuprate (I) ion in the center of cornea results in(More)
The paper presents the results of practical application of a new screening method for determining tolerant intraocular pressure (TIOP) on a Blood Flow Analyzer (Paradigm, USA). Studies were conducted on 331 eyes (205 subjects). Group 1 consisted of 80 patients (126 eyes) without glaucoma being found, with intraocular pressure (IOP) in the average normal(More)
In the period after surgical correction of myopia and astigmatism in 30 patients (44 eyes) by radial keratotomy, contrast sensitivity deteriorated slightly. The disturbances, however, were transitory, and the general trend was toward restoration of function. Strict adherence to an adequate operative technique prevented a marked decline in contrast(More)
Characteristics of ocular blood flow (OBF) in primary open-angle glaucoma (POAG) in eyes with optic disc drusen have been investigated. The study enrolled 21 patient (35 eyes) with optic disc drusen, of which 7 (8 eyes) were diagnosed with POAG. Besides the standard tests, the ophthalmological assessment included evaluation of OBF (flowmetry) and an(More)
The results of 257 combined, pathogenically oriented operations were analyzed in 181 patients with cataract concurrent with open-angle glaucoma (OAG). A system of pathogenically oriented combined surgical interventions was shown to be highly effective in patients with cataract concurrent with OAG. The proposed procedure for intraoperative determination of(More)
In this article the results of practical use of central retinal zone (CRZ) tomography in primary open-angle glaucoma (POAG) measured with RTA (Retinal thickness Analyzer, Talia Technology Ltd., Israel) are presented. 460 patients (790 eyes) aged 45-85 years old were included into the study. Significant decrease of CRZ minimal thickness and perifoveal region(More)
Clinical estimation of different modifications of phacoemulsification revealed the formation of the second tunnel in the nucleus for its division into quadrants in "four-quadrant phaco" increases the required duration of ultrasonography (US) and irrigation, which causes greater endothelial losses associated with the use of nuclear breakdown by means of a(More)
The impact produced by incisions of 2 examined types on the corneal refraction was studied in 40 patients (40 eyes) shared between 2 groups according to an incision type. 5 mm tunnel self-sealing incisions of 2 types, i.e. temporal corneal one longer by 3 mm, and upper linear sclerocorneal one stabilized by horizontal suture, were made use of. The obtained(More)
A total of 78 patients (143 eyes) with low, medium and high degree myopia were assessed. Apart from standard ophthalmological tests, flowmetry and duplex ultrasound of ocular vessels were performed in all cases to evaluate volumetric and velocity parameters of ocular blood flow in relation to the length of anterior-posterior axis and the degree of myopia.(More)
