A detached retina occurs when fluid from inside the eye moves through a retinal tear and underneath the retina, causing rapid vision loss and the need for urgent treatment.

The retina is a thin layer of tissue that lines the inside of the back of the eye. Light that enters the eye is focused on the retina, which then sends the images to the brain.

Sometimes, tears or holes form in the retina, particularly around the ages of 50-70. These holes may allow fluid from inside the eye to move under the retina, causing it to separate (detach) from the back of the eye. In most cases, a detached retina occurs spontaneously without any previous trauma.

Symptoms of a detached retina include flashes of light, new floaters, and a grey curtain in the vision. Anyone experiencing these symptoms should seek an immediate dilated examination with an ophthalmologist.

Treatment for a detached retina is urgent and may involve laser, gas injection, or surgery. Even with treatment, a detached retina may lead to permanent vision loss or blindness.
