[Role of the gas composition of intraocular fluid in the regulation of intraocular circulation].

The recovery velocity of the acido-alkaline state of the intraocular fluid depended upon the ocular hemodynamics in the rabbit intraocular chamber. Oppressive action of hyperoxia and substitute hypocapnia on intraocular blood circulation was revealed. The RQ reduction described in some eye diseases and after intraocular operations can be connected with changes in gaseous composition of the intraocular fluid.

[Correlations between clinico-functional and computerized tomography parameters in patients with optic atrophy of diverse etiology].

Comprehensive examinations of the optic nerve anatomy and function in atrophies of various origins have revealed a correlation between computerized tomography data and clinical and functional characteristics in 67 patients. A staged pattern of the development of anatomic shifts corresponding to CT data on the changes in the optic nerve diameter and density in accord with the length of the disease has been determined, as well as a relationship between these shifts and the patients' age and the degree of the calcification of the internal carotid arterial walls. CT signs of the optic nerve atrophy are related to functional disorders. Impaired circulation in the internal carotid arteries augments the atrophic process in the optic nerve. These data may be useful for the selection of a method for the management of optic nerve atrophy and for assessment of the treatment efficacy.

[Computerized tomography of the orbit and optic nerve canals in optic nerve atrophy of diverse etiology].

Computerized tomography has been used to examine 10 patients with cranial injuries aftereffects presenting as optic nerve atrophies (Group 1), 24 patients with nontraumatic optic nerve atrophies (Group 2), and 89 subjects without optic nerve abnormalities. Density asymmetry in the projection of the optic nerve canal cranial openings has been the computerized tomography sign that indicated the involvement of the optic nerve in Group 1 patients. Increased pneumatization of the main bone sinus has been detected 2 times more frequently in Group 2 patients.
