Background: Although changes in retinal vessel diameter is a new biomarker for the evaluation of cardiovascular risk factors, limited information is available regarding the effects of endurance exercises on retinal microcirculation. Thus, we aimed to evaluate both chronic and acute effects of soccer game on the diameters of retinal vessels in middle-aged players.

Methods: Retinal vessel diameters were measured in 12 middle-aged amateur players (44.

Coats' disease is an idiopathic disorder defined by an abnormal development of retinal vessels with a progressive deposition of intraretinal or subretinal exudates, leading to exudative retinal detachment. The most difficult task is to differentiate Coats' disease from retinoblastoma. We present a rare case of Coats' disease diagnosed in a 3-year-old girl.

Algorithms and software were developed for analysis of B-scan ultrasonic signals acquired from commercial diagnostic ultrasound system. The algorithms process raw ultrasonic signals in backscattered spectrum domain, which is obtained using two time-frequency methods: short-time Fourier and Hilbert-Huang transformations. The signals from selected regions of eye tissues are characterized by parameters: B-scan envelope amplitude, approximated spectral slope, approximated spectral intercept, mean instantaneous frequency, mean instantaneous bandwidth, and parameters of Nakagami distribution characterizing Hilbert-Huang transformation output.

Objective And Aim: In routine clinical practice, laser methods for the evaluation of optic disc parameters are expensive and not accessible for all ophthalmologists; therefore, there is a need for less expensive technique. The aim of this study was to assess correlations between the parameters of the optic disc measured by digital planimetry (DP), optical coherence tomography (OCT), and confocal scanning laser ophthalmoscopy (CSLO) in healthy and glaucoma patients with the normal biometric parameters of the eye.

Material And Methods: This case-control study enrolled 40 patients with glaucoma and 32 healthy patients with the normal biometric parameters of the eye.

Purpose: To assess whether patients with early or intermediate forms of age-related macular degeneration (AMD) benefit from cataract surgery in terms of visual acuity and contrast sensitivity, and to determine the levels of high sensitivity C-reactive protein (hsCRP) as a systemic marker of inflammation before and after cataract surgery in patients with AMD.

Methods: Three groups of patients (n=132) were studied at baseline and 8-12 weeks later: 1) a study group of patients with AMD who underwent cataract surgery (n=47), 2) a control group of patients without ocular comorbidities who underwent cataract surgery (n=36), and 3) a second control group with AMD and no surgery (n=49). Visual acuity (VA) was obtained by letter charts and expressed as decimal notations +/- SD.

In 2003, a health IT programme for clinical decision support started in Lithuania. An initial goal was to create databases for ophthalmology images and to develop processing algorithms to extract diagnostically valuable information from images. We have investigated how vectors, consisting of the parameters derived from fundus images, are distributed and whether they form specific groups.

The use of existing possibilities of Telemedicine Center of Kaunas University of Medicine allows the live distant consultations from high-level medical specialised centers to rural areas. On July 2004 the Telemedicine Center took part in the RESCUER/MEDCEUR project exercise. A special objective was the use of telemedicine facilities for distant consultations and sorting of victims directly at the event place.

The paper discusses possibilities to increase information value of ultrasound investigations in diagnostics of intraocular tumors by means of a developed informative system of acoustic diagnostics ISAD-2 on the basis of a microcomputer "Electronika-60" (OVK-2) and broad-band ultrasound piezo-transformer with a working frequency from 2 to 20 mHz. Examination of 50 patients (50 eyes) with suspected intraocular tumors resulted in enucleation of the eye ball in 45 patients (45 eyes). Comparison of ultrasound and histomorphologic investigations revealed a correlative connection between the structure of intraocular tumor and the texture of their radio-frequency echograms as well as with relative frequency dependence of ultrasound attenuation in it.
