Tobias, my African gray, has had tests from his vet, and has been seen twice by an opthamologist over An issue with his eye, that started nearly 2 years ago. He frequently closes one of his eyes. It's been a mystery, So I talked to Alison James, and she said she sensed he had a mineral buildup behind his eye, possibly calcium. Soooooo, What do you think Dr O found behind his eye today ,with an ultrasound??????? Calcium!!!! Initially there was probably not enough there to show up on ultrasound to be of concern, But it's there now, plain and clear. He's been closing his eye, more and more over the last couple years, so obviously, the increased calcium is making it worse. Alison Did not feel it was painful, And the vets and ophthalmologists, didn't think it was either.
