If your dog has uveitis in one or both eyes, they will have lower than normal pressures. If your dog has glaucoma in one or both eyes, they will have higher than normal pressures. The iris is examined with a focused beam of light and magnification for color, shape, pupil size, surface, and movement. The pupil will be shaped with spiked, jagged, or irregular edges. Checking your dog's intraocular pressures can check for glaucoma as well as uveitis. This is a very common condition in the eyes of double merles. Vision loss: Significant vision defects can affect pupil size and reactivity. Increased intracranial pressure: This can result from a brain tumor, meningitis (inflammation of the fluid around the brain), or a stroke. The stain will collect in the ulcer itself so that, even when excess stain is flushed out of the eye, the stain will still fluoresce under a black light. Trauma: An injury affecting the eye or the brain may cause the pupils to be unequal. This phenomenon is caused by the lack of physiological constraints in the GAN models. There are several potential causes of an altered pupil size in dogs, including inflammation in the frontal region of the eye, increased pressure in the eye, diseases that are focused in the iris tissue itself, a poorly developed iris, scar tissue build up in the eye, medications, and cancer. In this work, we show that GAN-generated faces can be exposed via irregular pupil shapes. All this to say, you may think your dog just has funky tears when in reality he has a lack of them! Staining the eye with fluorescein dye can illuminate any ulcers on your dog's cornea. Generative adversary network (GAN) generated high-realistic human faces have been used as profile images for fake social media accounts and are visually challenging to discern from real ones. Your dog's eyes will actually try to compensate but instead of tears they may produce a thick, sticky discharge. There are certain disease processes that will inhibit tear production. If a person has coloboma of the eyelid, part of the eyelid may be absent, and if they have coloboma of the iris, they may have irregularly shaped pupils. A Schirmer tear test will check the ability of your dog's eyes to create tears. Essentially, the term coloboma is used to describe the condition where a portion of tissue is completely missing from the eye or eyelid. Most eye workups will start with three basic tests: A Schirmer tear test, fluorescein stain, and an intraocular pressure test.
