WebDec 4, 2015 · For this purpose, we transfected retinal ganglion cells in vivo in the retinas of 11 months old DBA/2J mice. DBA/2J mice develop increased intraocular pressure and glaucomatous loss of ganglion cells as a result of an iris stroma disease by a mechanism that is similar to pigmentary glaucoma observed in humans [ 17, 18 ]. WebJan 29, 2015 · Preglaucomatous DBA/2J mice received memantine (5 mg/kg, intraperitoneal injection, twice daily for 3 months) and IOP in the eyes was measured monthly. RGC loss was counted after FluoroGold labeling.
