| Research Abstract |
Prostaglandin (PG) analogues lower IOP and have been widely used as ocular hypotensive drugs for the treatment of glaucoma. We investigated the effect of this drugs on ocular circulation. Topical PG also increases ocular blood flow measured by the laser speckle method. PG analogues also concentration-dependently relaxed mouse ciliary artery in vitro. This relaxation was also observed in prostanoid FP receptor-deficient mouse ciliary arteries. Thus, we conclude that the PG analogues relaxes ciliary arteries not dependent on prostanoid FP receptors
