Аннотация
PURPOSE: The aim of the study was to evaluate the blood flow in central retinal artery (CRA) in primary open angle glaucoma (POAG) and normal tension glaucoma (NTG).
MATERIAL AND METHODS: Two groups of patients were examined: I group consisted of 15 patients (19 eyes) with POAG, II group of 16 patients (32 eyes) with NTG. The controls were age-matched healthy persons. Blood flow velocities and resistance index in central retinal artery were measured by DRG Retina-Doppler.
RESULTS: We found decreased blood flow velocity in CRA in most of the patients with NTG and in part of the patients with POAG. Significant increase of resistance index was found only in NTG group.
CONCLUSION: Our study confirmed that assessment of the blood flow in central retinal artery appears to be a valuable method in diagnosis of neuropathy mechanism in glaucoma.
