Today his eye that has been gradually been getting worse looks very swollen and red. He has been rubbing it over the past few days on his rope perch, and he has feather loss all around it. His retina and iris are going completely burgundy (like his other blind eye), and now he has a big white spot on the surface of his eye that looks very painful. He keeps both eyes closed now, all of the time

I love this little guy. What can I do for him? Should I try to give him something for his swollen eye? Any help would be appreciated.
