title: Atrial natriuretic peptides. Effects on intraocular pressure, cGMP, and aqueous flow.
abstract: We report a significant decrease in intraocular pressure after intravitreal injection of atrial natriuretic peptide (AP). There is also an increase in cGMP in iris-ciliary body preparations after exposure to physiologic concentrations of AP in vitro. We present evidence that after intravitreal AP administration there is a decrease in aqueous humor flow associated with the decrease in intraocular pressure. The changes in aqueous humor flow were estimated by automated fluorophotometry and aqueous humor ascorbate concentrations.
