Experimental glaucoma models. A) The most usual animal models utilized in glaucoma research have been set up in mice, rat and mini pig. B) Experimental rat model of chronic glaucoma by seriate intracameral injections of sodium hyaluronate in the left eye vs balanced salt solution injection in the sham operated right eye [92]. C) rat ocular tonometry. D) Whole mount retinal staining of the RGCs in the non glaucomatous rat eye, and E) showing the significant decrease in RGCs density in the induced glaucoma eye (left).
