title: Axial and para-axial fluorophotometry in glaucoma simplex.
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).
