Retinal detachment: the warning signs, who is at risk, the eye exam, and treatment
For anyone who suddenly sees a lot of new floaters, flashes of light, or a shadow like a curtain over part of their vision; anyone with a few floaters who wonders whether they are normal; anyone who was hit in the eye; anyone at higher risk because of a past detachment, family history, eye surgery, extreme nearsightedness or diabetes; anyone told they have a tear in the retina; and anyone facing surgery or just home from it. The National Eye Institute (NEI, part of the NIH) says retinal detachment happens when the retina, the light-sensitive tissue at the back of the eye, is pulled away from its normal position; that it is a medical emergency that can cause permanent vision loss; that with its warning signs you should go to your eye doctor or the emergency room right away; and that treatment works well, especially when it is caught early. This page passes on, by name, what NEI says: the warning signs, the 3 types and who is at higher risk, the eye exam, lowering the risk and the floaters that are normal, and laser, freezing and surgery. It builds the words to say to an eye doctor, and prints a card to keep.

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor or nurse has reviewed it. The facts were read on October 16, 2026 on five National Eye Institute (NIH) pages: Retinal Detachment (last updated November 5, 2025), Types and Causes of Retinal Detachment, Laser Surgery and Freeze Treatment for Retinal Tears and Surgery for Retinal Detachment (all three December 6, 2024), and Floaters (December 4, 2024). Ours: calling 911 if you cannot get to your eye doctor or an emergency room, and not driving yourself; 988 for thoughts of suicide; using the eye injury page for the first minutes after an injury; asking exactly how long to avoid flying, lifting, work or driving; what to bring to a dilated exam; the questions to ask at a visit; rides and health centers when money is tight; and the order of the steps. What we left out: the names of eye drops given after treatment, research news, clinical trials, and pages for providers. This page saves nothing and loads no trackers.
