The Effect of Topical Brimonidine on the Ocular Hemodynamics in Patients of POAG Using OCTA

Summary

Topical Brimonidine is a well-established topical antigalucoma, ocular hypotensive therapeutic that has been in use since 1996. Brimonidine stands out among other topical ocular hypotensives in that it has a neuroprotective effect that is independent of IOP reduction. This has been demonstrated in multiple animal and human controlled studies both in vivo and in vitro. The mechanisms proposed so far to account for this neuroprotection focus mainly on molecular level antiapoptotic effects and modulation of some excitatory stimuli like glutamate. In this study we try to test the hypothesis that a positive hemodynamic profile of Brimonidine on ocular blood flow may be responsible at least in part for its unique neuroprotective effects.
