The Feline Glaucoma

Aqueous humor is produced by the ciliary body by active secretion and filtration of plasma. Most of the aqueous humor flows from the posterior chamber, through the pupil, to the anterior chamber, and exit at the iridocorneal angle into the intrascleral venous plexus. The balance between formation and drainage maintains intraocular pressure. In glaucoma the pressure in the eye increased. Prolonged or recurrent elevation of intraocular pressure lead to degeneration of the retina and optic nerve. The presence of a “red eye”, corneal edema, mydriasis, blepharospasm, blidness, and buphtalmos can be seen. Pupillary light reflex may be slow or absent.
