My dog's eye has white discharge. Is it a cataract or something else?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Spatsie!
From your pictures, the affected area is either with in the anterior chamber or the corneal surface of the eye. It is not the lens so it is likely not nuclear sclerosis or a cataract. With glaucoma the eye is very red, enlarged, and painful. From your picture the sclera (white part of the eye) doens't apear red. Glaucomoa is diagnosed based on measuring the intra-ocular pressure of the eye with a tonopen or other device.
My worry is that the white substance is white blood cells (hypopyon) with in the anterior chamber (which can lead to glaucoma). Corneal ulcers, corneal abscesses, uveitis, and systemic illnesses commonly cause hypopyon. The other possibility is a severe corneal ulcer. Spatsie needs to have his eye examined by a Veterinarian.
I hope this helps and I wish you and Spatsie the best!
