Advantages and disadvantages of experimental glaucoma models


Glaucoma is a disease accompanied by a progressive degenerative lesion of the retinal ganglion cells and the optic nerve, being one of the leading causes of blindness all over the world. The search for the new drugs for the treatment of glaucoma, aimed directly at reducing intraocular pressure and neuroprotection, and in some cases neuroregeneration, is impossible without the creation of appropriate experimental models. The current variety of models does not always provide a sufficient level of functional changes or is accompanied by a number of disadvantages that impede further research. There is a wide variety of glaucoma models. This article discusses the main ones, as well as describes the advantages and disadvantages of glaucoma models performed in small laboratory animals. Hypertensive and normotensive models of glaucoma are described, which correlates with human pathogenesis. This review forms a representation and describes most models of glaucoma in rodents. The search for models of certain forms of glaucoma remains as an indisputable fact. Based on testable hypothesis and experimental validity this data should be interpreted in the context of the experiment. Despite modern achievements, the improvement of experimental techniques and the search for new models continues till the present day.
