Comparison of the Effects of Timolol, Brinzolamide, Brimonidine and Netarsudil in a Rabbit Model of Water Loading-Induced Ocular Hypertension

This study showed that timolol, brinzolamide, brimonidine and netarsudil have IOP-lowering effects in normotensive rabbits and in water loading-induced ocular hypertension model rabbits. In an ocular hypertension rabbit model, brimonidine and netarsudil, which promote aqueous humor outflow, exhibited stronger IOP-lowering effects than timolol and brinzolamide, which suppress aqueous humor production. These results could provide data for characterizing each medication. These data may aid in the development of new glaucoma medications through the combination of existing medications.
