[Experimental microscopy and photography of the bulbar conjunctiva capillaries].

The authors worked out a new method of in vivo observation and microphotography of the rabbit bulbar conjunctiva capillaries in this experiment. A Soviet-made luminescent contact microscope LUMAM K-1 (LOMO) was employed. In general, maximal magnification of this microscope for visual observation equals more than 600. The photographs for this experiment were made with magnifications of 150 and 200. A 10% sodium fluorescein solution was injected in the ear vein before the experiment (0.2 ml/kg of the body weight). The 500-unit, sensitive film was used for the photographs. Microvessel diameter was measured on the film with the help of a stereocamparator. As the data obtained demonstrate, conjunctival capillary diameter varied from 3 to 9 mcm, averaging 8 mcm. This method of contact biomicroscopy permits to the performance of capillarography and capillaroscopy of bulbar conjunctiva along with quantitative evaluation of capillary parameters and some reological indicators.
