Hello, I'm Dr Ralston.
Sorry your question was open for so long. I was looking back through old questions logs left by other vets, and it appears that this question may have fallen behind and gotten lost. There are not a lot of bird Vets on Just Answer. And so sometimes, unfortunately, this is possible.
So, I thought I would write to see if Angel has continued to have this eye problem?
This happens in African greys' a lot. It can happen if they have been feather plucking or over grooming. In this case, they might loose all their feathers. However, in the case of avian conjunctivitis (like pink eye), usually it is just on the side where the eye is itchy.
Does it look like this ?
Rarely, a patient will require antibiotics for the eye. Chlamydia is a common bacteria that infects the eyes. It affects cats as well, and the treatment is similar, so a local vet that sees cats should be able to also prescribe medications for you.
A homeopathic remedy for eye irritation in parrots has been described:
"One holistic treatment for swollen or bruised eyes due to minor eye trauma was described in the Avian Health forum. Darlene puts 1 to 2 drops 99.9% plain pure aloe vera juice at room temperature on the eye 6 to 8 times a day. She reports that within 2 or 3 days the eye is back to normal. She recommends this procedure one day more once the eye is back to normal. Even though this should be administered at room temperature, it is important to store the aloe vera juice in the refrigerator in between treatments. Take out a portion a while before administering it to allow it to warm up to room temperature. Please note this is only for bruised or swollen eyes due to injury. More serious injuries should be treated by an avian vet." - Avianweb.com
Anyway, again, just trying to help.
Please do not leave a negative review as this is the first time I have seen this question today. It was passed over by other Vets, and I am just trying to help.
