Autosomal recessive, primary open - angle glaucoma (POAG) has been very well characterized in the Beagle [142 — 146] and a Gly661Arg variant in ADAMTS10 has been associated with the condition in Beagles that developed elevated intraocular pressure from 8 to 16 months of age, due to increased resistance to outflow of aqueous humour despite normal appearing open iridocorneal angles [147].

These primary glaucomas are categorized further into open - angle, narrow - angle, and closed - angle glaucoma by gonioscopic examination of the iridocorneal angle, and are breed specific. (campcocker.com)
Additional diagnostic tests may be required for your pet, such as Schirmer tear testing for dry eye, tonometry (measuring the intraocular pressure), refraction (to determine the optics of the eyes), gonioscopy (to determine the anatomy of the iridocorneal angle). (eye-vet.com)
