Plain-English summary
A dog with secondary glaucoma may show signs like squinting, redness in the eye, or excessive tearing. This condition happens when the fluid in the eye can't drain properly, leading to increased pressure. Diagnosing secondary glaucoma requires thorough testing, and treating it can be tricky since standard treatments for primary glaucoma might not work. However, if the underlying cause is identified and treated quickly, the chances of saving the dog's vision can be better than with primary glaucoma.

Abstract
Secondary glaucomas are common in dogs, and occur due to obstruction of aqueous humor flow at the pupil, iridocorneal angle, or trabecular meshwork by numerous mechanisms. Secondary glaucoma is suspected based on examination findings, or presence of elevated IOP in an animal with a signalment inconsistent with primary glaucoma. Animals with secondary glaucoma require more diagnostic testing than animals with primary glaucoma. Management is challenging, and treatments used for primary glaucoma may be ineffective or even detrimental. Prognosis for vision and/or globe retention may be better than for primary glaucoma, particularly if underlying causes can be found and addressed promptly.
