Fluorophotometric determination of aqueous humor flow rates in red-tailed hawks (Buteo jamaicensis)

Abstract

The AHFR in red-tailed hawks was similar to that of most mammalian species, and the fractional egress was almost identical to that of other species. This information will allow a greater understanding of aqueous humor flow in avian eyes, which is crucial when evaluating diseases that affect avian eyes as well as medications that alter aqueous humor flow.

Comparative evaluation of aqueous humor viscosity

“…Interestingly, many conditions that commonly affect our mammalian species are infrequently appreciated in birds of prey. In particular, primary glaucoma is rarely documented in birds . Although spontaneous forms of primary glaucoma have been reported in the Slate turkey ( Melagras gallapavo ) and in the Japanese albino mutant quail ( Coturnix coturniz japonica ), occurrence rates in other avian species, including raptors, are rather sporadic and avian species more commonly develop glaucoma secondary to trauma and or uveitis .…”
