[Transport processes of fluid exchange in the crystalline lens of the rabbit eye].

Processes of fluid exchange in the crystalline lens of the rabbit eye were investigated. The direction of movement of fluid in the crystalline lens was investigated from the movement of fluorescein by the method of "stopped diffusion". It has been found that the mechanism of fluid transport in the crystalline lens is active and is carried out by means of the Na-kappa-ATPase transport system. The energy necessary for the active transport of fluid inside the crystalline lens is in the range (1.5-6) x 10(-2) J. Owing to the active fluid transport, the pressure inside the crystalline lens constantly increases by 6 mm Hg. In rabbit's life-time, the movement of fluid in the crystalline lens occurs in the direction from the anterior to the posterior surface followed by the exit to vitreous humor.

Direction of fluid transport in the lens.

The direction of fluid flow in rabbits was studied in vivo by the distribution of fluorescein in eye structures. Fluorescein was administered into the central part of the lens. Fluorescein migrated from the anterior to posterior surface of the lens and then appeared in the vitreous body. Fluorescein did not migrate to the anterior surface and did not appear in the anterior chamber of the eye.

[Experience in the undergraduate training of ophthalmologists]. / Opyt podgotovki spetsialistov-oftal'mologov v subordinature.

The authors present their experience gained in the training of ophthalmologists at the Chair of Ocular Diseases of the Krasnoyarsk Medical Institute. In 1991 the interns, instead of traditional state examinations, maintained their diploma research, which was assessed as their skills and knowledge in the field of ocular diseases, social hygiene, and public health organization. The authors prove that such diploma research is an integral part of undergraduate training and one of the types of individual work at higher educational institutions, and enumerate the topics of diploma research.

The paper generalizes the experience of work of an optimized variant of the system of urgent aid and treatment of patients with eye traumas, an ophthalmological centre, organized on the basis of the Department of Urgent/Ophthalmological Aid and the Department of Vitreo-Retinal Surgery. The authors describe results after IOL implantation in removal of traumatic cataract and treatment of corneal wounds, diascleral removal of foreign bodies, localized paramacularly, from the posterior segment of the eye the usage of extracapsular transmembranous dialysis of antibiotics for treatment of intraocular infection. All this allowed to essentially improve outcomes after severe eye traumas.
