I need some advice on what to do next. My one year old little girl has been squinting her one eye for a couple of weeks now. I brought her to the vet and they said it may be herpes but didn't test for it specifically. She gave me an antibiotic to cover any bacterial infection and advised to add a lysine supplement which i have. The eye does not have discharge, she has no other symptoms, the vet said there was no abrasion, and her third eyelid is not showing nor does it look inflamed. She is just randomly squinting her one eye especially when she is tired. Sometimes it looks normal but it is slightly closed more often than not. Has anyone else had any experience with something like this? I'm not sure what else to do so any advice would be much appreciated.
