Pigmented lattice degeneration7/22/2023 ![]() ![]() ![]() The most common cause of rhegmatogenous detachment is aging. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision. This fluid builds up and causes the retina to pull away from underlying tissues. Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina. These types of retinal detachments are the most common. There are three different types of retinal detachment: Most eye floaters don't require treatment, but your eye doctor likely will recommend regular eye exams to ensure the condition doesn't worsen.įor the Mayo Clinic Newsnetwork, I'm Jason Howland. Howland: And that can cause blindness, which is why it's especially important to have a dilated eye exam within days of noticing new floaters or changes in vision. Khan: If a tear develops in the retina, fluid can get in underneath that tear and just lift the retina off like wallpaper off a wall and that's a retinal detachment. The biggest concern – they can cause retinal tears.ĭr. Howland: Eye floaters are more common as you get older and if you're nearsighted. Those smaller pieces are what you may notice as floater. As we age, this firm clump of jelly can liquefy and break up into smaller pieces. Benson, MD.Jason Howland: Having vision problems? Do you see black or gray specks, strings or cobwebs that drift about when you move your eyes? It could be eye floaters.Īmir Khan, M.D., Consultant, Ophthalmology, Mayo Clinic: In the back of our eyes, we have a substance called "the vitreous." When we're young, it's a firm clump of jelly.
