Welcome to JustAnswer.com and thank you for your post!
Based on your description, possible causes may include:- Infection- Corneal ulcer or abrasion
- Viral URI- etc.When I am presented with a case such as this, tests that I would consider include:- Using a special test to see if there is corneal damage (Fluoroscein)- Measuring the pressure in the eye to test for glaucoma- Looking into the eye with a light and a special lens to look at the retina
To get to the bottom of this - I would recommend a visit to your veterinarian - as specific medications such as antibiotics may be needed.To start - you can certainly offer some care at home - you can try to lubricate and flush the eye with saline solution. You can go to the pharmacy and ask for ophthalmic saline, or have a look in the contact lens section. You can flush the eyes 2-3 times per day.I hope this information helps!
