I have colabomas in both eyes, left is on my retina and no bother at all, right is on my optic disc and has caused loss of peripheral vision.
Unfortunately where it is it has caused an optic disc pit which lets vitreous fluid in under my retina which caused something called Serous Macular Detachment basically my retina was being pushed up out of place. Then the fluid would recede, then build... over and over
A couple of years ago a yearly check showed a massive vision loss and the only option was surgery.
While awake, I had keyhole surgery in my eye, all the vitreous fluid removed, retina stitched back into place, then laser to seal the edges down, my lens was removed and replaced with a plastic one then a gas bubble was inserted to hold the Retina flat while the vitreous fluid regrew.
I had to lay face down for 3 days, if moving around I had to stay bent at the waist 90 degrees with nose parallel to the floor. A maximum of 10 mins in every hour was allowed out of a completely face down position.
Took about 2 weeks for the stitches on the surface of my eye to dissolve and for the fluid to rest build, over that 2 weeks I could feel the stitches when I blinked and I couldn't see through the gas at all.
Sounds horrible but honestly my eye did not hurt, neck/back/shoulders were sore from the position but that's it, I was completely calm for the surgery, drops meant I couldn't see a thing that happened and my good eye was covered.
I was completely lucid and on my way home half an hour after the surgery, then had a few visits for check ups over the next few weeks
It didn't improve my eyesight but it stopped it getting any worse and I thank everything for that, 2 weeks of complete blackness in that eye was enough for me to know I never want to be blind!!!!!
