[Comparative assessment of hemodynamic risk factors of glaucomatous optic neuropathy progress]

Comparative evaluation of the significance of hemodynamic factors of risk of progress of glaucomatous optic neuropathy has been carried out: blood flow velocity, blood flow resistance, blood pressure in the orbital artery-central retinal artery system, perfusion ocular pressure in connection with stabilization of glaucomatous process, and intraocular pressure were analyzed for a period of up to 16 years. The most significant factors were blood pressure in the orbital artery-central retinal artery system and perfusion ocular pressure, but not blood flow velocity. The leading factor indicating the risk of progress of optic neuropathy in primary glaucoma is ocular perfusion pressure. Measurements of opthalmodynamometric pressure can be used for evaluation of perfusion pressure and recommended for wide clinical application for predicting the course of primary glaucoma.
