Should I keep the parrott?

Optometrist said the retinal scar in my eye might have come from the bird (blue-fronted amazon)-even though I bought it from a bird shop in New Jersey pre 1987 and it has never met another bird before or it did meet other parrots one time but was not in the same cage with any of them.The bird is about 24 years of age and use to sit on my shoulder all the time until i read that after 20 years of age they can change and cause facial injuries and I have never put him back up there on my shouder and thus now with information that he might have caused a retinal scar I'm wondering if  I should leave him to  a bird sanctuary or sell him outright -since we do not have the same bond since I stopped putting him on my shoulder.and really don't have too much interaction with him anymore.

As for having the retinal scar I would not question the optometrist as these scars can happen for various reasons such as blunt injury to the eye, extended intense light (reason why you shouldn't look at a solar eclipse directly), severe infection of the eye, or diseases that can affect the eyes such as diabetes. As for the bird being the cause...extremely unlikely.
The retina lines the inner perimeter of the eye globe and serves as a nerve and blood rich light receiver which acts like film in a camera and then sends that impulse through the optic nerve to the brain to translate into an image. The important part the retina is in the BACK of the eye where light will hit. So unless the bird attacked and severely injured your eyeball to reach into and toward the back of the globe then the bird is not the cause of the scar. Exceptions to an attack would be if a feather or dander from the bird got into your eye and did damage...however this would be something you would know right away as it would be extremely painful.
As for the bird changing after 20 years and causing facial injury this is true with some birds and is in regards because the birds tend to get nippy. As with any part of the body a bite can do injury. Its just facial skin is easier to injure because the skin its not rough and protected as much like the soles of your feet or hands. However, either way as for the retina the bird is likely not at fault since access to bite the retina would take great skill without greatly objecting to the attack and stopping it before injury.
As for selling him or giving to a sanctuary, this may still be something if you don't share a bond anymore. I guess it would just be a matter if you mind or not having him around and still provide his basic needs. Some people do like to just have pets that serve more as casual company rather than being "part of the family". So its just up to how you feel. I would just say that the retinal scar should not be a reason to get rid of him as him being the cause is so unlikely.

Whtroze gave an excellent answer, explained things very well.

I agree that if the bird is not being nippy or aggressive, there's no need to send him away. If the bird was used to spending time with you and now is being ignored a bit, he may wonder what's going on. That may change his behavior since parrots are so social. If you enjoy having him with you, try spending time that is not so much face to face time. There's so much more you can do with him.

Well I feel much better with your answer and an opthomologist later on said basically she doesn't know what caused the scar.Thanks for your answer and I guess Hector will be staying around much longer than I thought.
