Thank you for submitting your question regarding Pepples. The pictures you submitted are very helpful. It appears as though her conjuctiva (the tissue under her eyelids) is very red and swollen. She also appears to have cloudiness to her cornea (the surface or her eye) and tiny vessels growing across it. She will need to see her veterinarian to determine the cause of these changes. She could be suffering from a corneal ulcer (scratch to the surface of the eye). There is also a condition that is common in her breed that causes decreased tear production. Once she has a diagnosis, treatment can be started and she will begin to feel better. Good luck!

    I strongly recommend urgent referral to a specialist ophthalmologist to assess fully the extent of the condition. Glaucoma or increased pressure in the eye can cause bulging, redness and swelling in the surface/blue clouding and can be extremely painful, but so can many other conditions. An eye pressure check is recommended urgently in order to rule out this painful condition which can threaten vision
