Unequal pupil size bipolar
Rest assured, veterinary medicine doesn't check eye pressures with the dreaded 'air puff' test that is common in human ophthalmology.

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. Checking your dog's intraocular pressures can check for glaucoma as well as uveitis. 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. 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. The difference in pupil size will be less than or equal to 1 mm, and the condition may be intermittent, persistent, or self-resolving. This particular type can affect up to 20 of the population. Your dog's eyes will actually try to compensate but instead of tears they may produce a thick, sticky discharge. Simple anisocoria (otherwise known as physiologic or essential) is the most frequent cause of uneven pupil sizes. There are certain disease processes that will inhibit tear production. A Schirmer tear test will check the ability of your dog's eyes to create tears. Most eye workups will start with three basic tests: A Schirmer tear test, fluorescein stain, and an intraocular pressure test. People rarely realize it themselves that they have unequal pupils.They.

2, 3 If the anisocoria is exaggerated in dim light, the small. In physiologic anisocoria, the difference in pupil size remains the same in both bright and dim ambient light, and is usually less than 1 mm. Diagnosing the Reason for Your Dog's Anisocoria Anyone can have pupils that differ in size with no problem.In fact,epidemiologically,one out of five people have pupils that are normally of different sizes.Not withstanding the aforementioned,there may be clinically cautions for a serious eye problems when seen.Namely. Normally, both pupils constrict equally in bright ambient light and dilate equally in dim ambient light.
