Dog lost vision and has green eyes after tick bite. What's wrong?

Should the eye ointment not make a difference in his loss of vision, I suggest you take Izzy back to the vet for a recheck. there are quite a few causes of blindness possible. Ask your vet about testing for tick diseases. we do sometimes see dogs with an ehrlichia canis infection that temporarily go blind. It also may be that she was slowly going blind over the past few years and now finally is totally blind and you just did not notice it before. THis is difficult, but dogs are great. They can get used to being blind easily, and have a few more senses with which they can "see".

Poor guy. He needs his eyes flushed copiously with eye irrigating solution. You can find this over the counter. It is a potential that he could develop a corneal ulcer due to the chemicals from the spray. Blindness is a potential but it is preventable as long as you monitor this closely. Monitor his eyes for redness, discharge (yellow/green), or irriation (pawing at the face). Have Bruno seen by your vet right away if these complications develop. For future, the fipronil sprays are not the best to use for tick prevention. I would instead recommend the Seresto collar, or oral flea/tick prevention (Nexgard, Bravecto) from your vet. For acute bites, you should use tweezers to remove the tick (must get the head and mouthparts) entirely. I hope that your fur baby Bruno does well moving forward. Take care! : )

Occasionally tick bites can become infected although it is not very common. It's also possible that this is a growth on the eyelid and not related to the original tick bite. I think it should be okay to wait until your vet appointment as long as your dog is not squinting and you don't notice cloudiness of the eye itself or any discharge.

Diana needs to be seen by a veterinarian for an eye exam ASAP. There are quite a few conditions that can cause this, e.g. glaucoma, keratitis and even Ehrlichiosis, caused by a blood parasite. immune disease, trauma to the optic nerve, and canine distemper, etc. Treatment (some blindness can be reversed) will depend on the diagnosis.

If it's just the one eye there may be something going on on the corneal surface that you can't see with the naked eye. A vet would need to stain the eye to see a scratch. I would recommend taking him in to check that and get medications to heal it fast. Eyes can go from bad to worse very quickly. Good luck and kisses to Tucker!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. I suspect the blister is a corneal ulcer. Corneal ulcers are usually caused by a trauma to the eye bulb or from contact with substances (chemicals) that are very irritant to the eye. I don' think it is caused by ticks or fleas. Please, take your dog to your local vets for an appointment right away as untreated corneal lesions (regardless of the cause) can easily turn into an infected ulcer, which can be very difficult to treat.

This is an emergency. Your dog needs to be seen by a veterinarian right away. Sudden loss of eye sight can be caused by many conditions, inherited/congenital eye disease, tick borne disease (Ehrlichiosis), diseases of the retina, SARDS (usually in older dogs), Inflammatory, autoimmune, or allergic causes and many more. Please take Buddy to a veterinarian now.
