ABSTRACT
To evaluate the protective effects of intravitreal injection of cannabinoid HU - 211 for optic nerve in glaucoma rats, providing the experimental evidence in the treatment of glaucoma optic nerve injury. ●METHODS: Glaucoma rats (18 eyes) were modeled by electric coagulation sclera surface vein and randomized into 3 groups, group A received intravitreal injection of 1mg/ 0. 1mL cannabinoid HU - 211 every other day respectively; group B was given intravitreal injection of 0. 1mL water every other day, group C was high intraocular pressure (lOP) group, 6 eyes were randomly selected for blank control group ( group D). lOP was observed every day. The rats were sacrificed after treatment 4wk, froze retina section, HE stain. The density fluctuation of retinal ganglion cell ( RGC ) neurons assessment the optic nerve of rat model with chronic high lOP glaucoma were measured. ●RESULTS: The apoptosis and damage degree of RGC in group B was obviously higher than that in group A, with statistically significant difference (P0. 05). ●CONCLUSlON: lntravitreal injection of cannabinoid HU-211 shows obvious protective effect on optic nerve in glaucom rat models.
