Aqueous outflow system pulsatile flow abnormalities observed in glaucoma.

Finding	Details
Few aqueous veins with pulsatile flow identified.	Suggests diminished ability of outflow tissues to fill aqueous veins.
Pulsatile flow in visible veins decreased or absent.	Abnormality of tissues generating pulsatile flow.
Medication instillation increases pulsatile flow.	After new medication-induced lower homeostatic setpoint is reached, pulsatile flow slows.
Prior to instillation of next pilocarpine dosage pulsatile flow diminishes or stops and intraocular pressure rises.	Pilocarpine short duration of actions makes effect apparent.
Aqueous influx phenomenon in normals changes to blood influx phenomenon in glaucoma.	Follows occlusion of distal recipient aqueous vein.
“Compensation maximum” (Performed with ophthalmodynamometry)	Normal response of an increase of pulsatile aqueous vein flow caused by pressure on eye is reduced or absent.
