answer:You need to take her to the veterinarian. They will use a fluoroscein stain to determine if she has a scratch on the surface of her eye (a corneal abrasion); this is vital to determining the proper treatment for her eye. They will also check to make sure that she does not have a foreign body caught in her conjunctiva. If she has a corneal abrasion, they will provide you with an antibiotic ointment (or drops) as well as a topical pain medication. In very severe cases, they may also supply a systemic pain medication. If there is no sign of damage to the surface of the eye, they will be able to use an ophthalmic steroid as well as an antibiotic treatment – this will help with the inflammation and pain. (Using a steroid on an eye with a scratch is detrimental to healing, and in some cases can contribute to an ocular rupture. That’s why the diagnostic fluoroscein stain is so very important.) If she’s been recently adopted, it’s likely that she has some form of upper respiratory virus causing the eye irritation, but her rubbing at it could make it quickly worse (she could scratch the surface of the eye herself), so I would have her looked at as soon as possible.
