low-pressure glaucoma, retinal ganglion cells, optic nerve, polarized green light, fl uorescent dye


Aim. Glaucoma is a disease characterized by a decrease in visual acuity, narrowing of the visual fi elds due to damage of retinal ganglion cells under the infl uence of increased intraocular pressure. Low-pressure glaucoma (normotensive glaucoma) is a progressive neuropathy of the optic nerve without an increase in intraocular pressure, characterized by narrowing of the fi elds, decreased visual acuity, or development of complete blindness with an atrophy of optic nerve discs. The aim of this study was to analyze the vitality of retinal ganglion cells, which are affected by glaucoma, after their specifi c identifi cation.
Materials and methods. In this study, retinal ganglion cells were identifi ed by the injection of the fl uorescent dye Fluorogold into the structures where the axons of these cells terminate, namely, the superior colliculi of the midbrain.
Experimental low-pressure glaucoma in rats was induced by damage to the optic nerves.
Results and discussion. Here, we shown that in rats with experimental glaucoma the amount of ganglion cells in the retina is signifi cantly reduced in comparison with control animals. The analysis of the effect of polarized light on ganglionic cells of the retina in the model of experimental glaucoma in rats did not reveal any signifi cant differences from the control.
