Example text

These names arose from attempts to describe a relatively undefined seepage route. It would be more accurate to refer to this drainage as simply ‘uveal’ outflow, to include all anterior chamber aqueous humor egress from the uvea. The term appearing most often in the literature is ‘uveoscleral outflow’ hence its use in this chapter. In contrast to trabecular outflow, uveoscleral outflow is effectively pressure independent. 02 ␮l/min per mmHg). Uveoscleral outflow reportedly accounts for anywhere from 4 to 45% of total aqueous drainage in humans.

Another method to determine aqueous flow in humans was a non-invasive photogrammetric technique. With the anterior chamber filled with fluorescein, freshly secreted aqueous humor appeared as a clear bubble in the pupil. The increase in volume of this bubble was determined by geometric optics and was an indication of the rate of aqueous flow. Currently the method of choice to assess aqueous flow is fluorophotometry. 10) or by corneal iontophoresis. 11). When an equilibrium has been established, the concentrations of fluorescein in the cornea (Cc) and the anterior chamber (Ca) decrease over time.
