[Normal-pressure glaucoma].
Normal tension glaucoma is defined as a clinical condition in which the optic nerve head is pathologically excavated and the visual field is disturbed, although the intraocular pressure is in the normal range. The following pathogenetic factors are considered responsible: too high IOP (even lying within the normal range) and primary circulatory disturbances, such as arteriosclerosis, systemic hypotension, orthostatic hypotension, hyperviscosity and functional vasospasms. The purpose of a clinical evaluation is to define the most important damaging factors for the individual patient. Accordingly, the therapy is directed towards the possible factors involved. Practically, this can mean: additional lowering of the intraocular pressure, increasing the blood pressure, lowering the blood viscosity and treating the vasospasms.
