[Pathophysiological basis for decompression surgeries and their effect on the optic nerve scleral duct in cases of primary glaucoma].
The visual functions and hemodynamics of the optic-nerve and retina were examined before and after decompression surgeries in the optic nerve. The methods of ophthalmodynamometry and ultrasound dopplerography were used to study the optic-nerve hemodynamics. The results showed an essential improvement in the visual field and blood circulation of the optic nerve in 80.7% of operated patients. The obtained data are indicative of that a disturbed blood circulation in the optic-nerve initial portion plays an important role in the development and progressing of glaucomatous optic neuropathy. Decompression surgeries in the optic nerve in cases of a progressing worsening of the visual functions are pathogenetically substantiated for glaucomatous patients.
