Retinopathy and experience with air travel

I'm invited to a wedding in October, which I would really like to go to. It's going to require me getting on a plane. Driving is not an option in this case. I have have had my share of eye bleeds and extensive lasering over the past two years, multiple shots of Avastin, THE WORKS! Anyone else had experience with flying under these circumstances? Did you make out okay? Did the cabin pressure cause you any problems with your eyes? I know of one person with a similar eye situation as myself. He flew and the next day he had blood in his eye. This would be a sure-fired way to ruin the trip if that were to happen to me. Just wondering if anyone else had anything to add. My doctor says I'm okay to fly.
