title: [Iris examination in transformed light in primary open-angle glaucoma].
abstract: The iris was examined in transformed light by iridochromoscopy, iridochromophotography, biomicroscopy in polarized light, transillumination in red light, and fluorescent iridoangiography in 83 eyes of patients with primary open-angle glaucoma and 117 eyes of normal reference subjects. The examinations have shown the prevalence of trophic and vascular shifts in the iris of all glaucoma patients as against the reference patients (R 0.05). The major iris changes revealed in primary open-angle glaucoma were stromal atrophy with the predominant involvement of the pupil segment, destruction of the pupil pigmented border, exogenic pigmentation of the pupil and ciliary segments, thickening of the anterior border layer, pseudoexfoliation of the pupil edge, defects of the posterior pigmented lamina disseminated in the pupil segment, hypoperfusion of the iris vessels combined with their impaired permeability and micro-neovascularization in the iris edge and ciliary agea.
