Different types of aqueous outflow
WebDec 28, 2016 · The aqueous humor flows out of Schlemm's canal through one of 30 collector channels and aqueous veins (AVs) and then to the system of suprascleral veins, ophthalmic veins, and general circulation. According to Poiseuille's law, the resistance of aqueous veins should be insignificant if they are not collapsed or compressed. WebThe uveoscleral outflow route was described more than 40 years ago. Part of aqueous leaves the eye through the iris root. The ciliary muscle, and there are large species differences in the fraction of aqueous outflow that leaves the eye through this route. In non-human primates 40-50% of aqueous leaves the eye by the uveoscleral route.

Aqueous humor outflow is a measurement of flow rate. Unlike the trabecular route, exit is diffuse and challenging to trace. The unconventional rate is measured with direct/tracer-based methods, and indirect methods. Direct methods are used to estimate both conventional and unconventional outflow via … See more Aqueous humor flows out of the eye primarily through the conventional outflow pathway that includes the trabecular meshwork and … See more To reduce IOP with a more rapid postoperative recovery and better safety ratings compared with traditional filtration surgery, minimally invasive glaucoma surgical devices are … See more Using the uveoscleral pathway for therapeutic purposes could involve both lowering of IOP and drug delivery via a transscleral approach.

WebThe aqueous outflow pump fails in glaucoma due to the loss of trabecular tissue elastance, as well as alterations in ciliary body tension. These processes lead to SC wall apposition and loss of motion. Visible evidence of pump failure includes a lack of pulsatile aqueous discharge into aqueous veins and reduced ability to reflux blood into SC.

WebAqueous shunts are comprised of a small silicone tube attached to a plate. Aqueous humor is drained from the eye via the tube and deposited into the plate, which sits on the sclera near the equator of the eye. All three types of shunts perform essentially the same function, but provide different advantages for regulating eye pressure following ...
