[Open-angle glaucoma yesterday and today].
Glaucoma with open angle is now considered as an early optical neuropathy, that is determined by an uneasiness in flowing of the aqueous humour at the trabecular level. The ocular hypertension is the most frequent manifestation of the evolution of glaucoma, but it is not obligatory because there is a glaucoma with open angle that develop with low pressure. The automatically perimetry and the photography of the retinal arcuate fibers in aneritre light, may evidence incipient lesions before increasing of the ocular tension. Stereophotographies of the optic papillae make possible the calculus of the neuroretinal ring surface that replaces the old ratio cup/disk. The investigation of the microcirculation of the papillae, the determination of the papillar blood tide by pneumotonography and the velocimetry laser Doppler have brought new data for determining the incipient lesions of the optic disk. The large utilization of beta-blockings has changed the life of a glaucoma patient and the filtrant surgery has extended and diversified so being prolonged the visual function.
