[Features of retinal hemodynamics and the optic nerve in developing primary atrophy in tumors of the chiasmal-sellar area].
The pathogenesis of primary optic atrophy of different severity, caused by tumors in the chiasmal-sellar area is analyzed as exemplified by 109 patients. The severity of primary optic atrophy depended on the duration of visual disorders. The patients were divided into 2 groups with early and late stages of visual disorders. Use of objective methods of examination (fluorescent angiography, densitometry, and fluorophotocalibrometry) helped detect the earliest changes in the fundus oculi microcirculation, accurately determine the severity of optic atrophy, and more completely evaluate the hemodynamic disorders in the ocular artery system.
