[Evaluation of the macular ganglion cell layer by spectral-domain optical coherence tomography in diagnosis of early-stage glaucoma].

The new Cirrus HD-OCT software was used to measure the thickness of ganglion cell and inner plexiform layers (GCIPL) in macular region in 56 patients (56 eyes) with early-stage primary open-angle glaucoma (POAG) and 53 healthy controls (53 eyes). The diagnostic value of the best parameters of GCIPL for POAG detection was insignificantly lower as compared to the best parameters of the peripapillary retinal nerve fiber layer and optic nerve head.

[Biochemical and physiological estimation of barley regenerants obtained in selective systems].

Callus lines of barley (Hordeum vulgare L.) resistant to aluminum toxicity and osmotic stress from which plants regenerated were obtained in selective systems. Comparative estimation of the intensity of lipid peroxidation, the content of anthocyans and ascorbic acid in leaves, the parameters of CO2/H2O gas exchange in leaves of regenerant plants obtained in selective mediums with gradual addition of aluminum ions and polyethylene glycol and in mediums without selective agents was performed in conditions of an artificial climate.

Comparison of measurement error of Cirrus HD-OCT and Heidelberg Retina Tomograph 3 in patients with early glaucomatous visual field defect.

Background: To compare the measurement error of Cirrus HD-OCT and Heidelberg Retina Tomograph 3 (HRT3) in patients with early glaucomatous visual field defect.

Methods: Thirty-nine consecutive patients (39 eyes) with early glaucomatous visual field defect were included. One eye of a patient was examined with Cirrus HD-OCT and HRT3 in one session.

[Evaluation of stereometric parameters of optic disc and nerve fiber layer using HRT II. Report 3: measurement error of spectral-domain optical coherence tomography compared with Heidelberg retinal tomograph III].

The aim was to study reproducibility and variability of measurements of retinal nerve fiber layer (RNFL) using spectral-domain optical coherence tomography (SOCT) and to compare with error of Heidelberg retinal tomograph (HRT). 29 patients with initial primary open-angle glaucoma were examined using Heidelberg retinal tomograph III (HRT III) and SOCT (Cirrus HD-OCT). Intra- and interobserver errors (reproducibility and intraobserver variability coefficient) for mean RNFL thickness and its thickness in temporal, upper, nasal and inferior quadrants.
