    Notes: Abstract The decomposition of carbon dioxide to carbon monoxide and oxygen in an argon plasma is studied. The overall kinetic and energy-related parameters of the process, as well as the quenching rates of the products, are evaluated on the basis of measured radial and longitudinal profiles of both temperature and degree of decomposition in the high-temperature reaction zone.

    Notes: Abstract In this fluorophotometric study, in 25 eyes with middle advanced stages of glaucoma simplex (visual field defects ranged from 500 dB to 800 dB) and treated with topical antiglaucomatous agents, the posterior vitreous penetration ratio (PVPR) was compared with that from normal subjects. Vitreous fluorophotometry (Fluorotron Master, Coherent) was used to measure posterior vitreous fluorescein concentration. Due to additional fixation light in horizontal plane, three scans were taken along the following directions: temporal (t), foveal (f), nasal (n). The angle of deviation from the foveal scan was 15 degrees in each direction. The average values of posterior vitreous penetration ratio in group of patients with glaucoma were higher in comparison with those in healthy subjects. In both groups the PVPR was significantly lower in nasal (n) scan (optic disc area) in comparison with temporal (t) or foveal (f) scans (p 〈 0.05).

    Notes: Abstract The vitreous fluorophotometric examinations were used in nonproliferative diabetic retinopathy to recognize early diabetic macular edema. Thanks to additional fixation light, axial and para-axial fluorophotometry in patients with nonproliferative diabetic retinopathy was achieved (Fluorotron Master, Coherent). The angle of deviation from the foveal scan (f) was 10 degrees in temporal (t) and nasal (n) directions. In case of non clinically significant macular edema, the posterior vitreous penetration ratio (PVPR) in the foveal scan (f) was significantly higher (p 〈 0.05) than in the other results (trend PVPRt 〈PVPRf〉 PVPRn).
