The retina is located at the back of the eye, and sends images to the brain through the optic nerve. The
retina can detach from its position at the back of the eyeball. The result is blurred vision. If not treated immediately, then there will be permanent vision loss.
The vitreous is the clear gel that fills the back of the eye between the retina and the lens. As you get older, the vitreous may pull away from its attachment and tear the retina. The tear allows vitreous fluid to seep through it under the retina, and peel the retina away.
A retinal detachment can occur at any age; however, it’s more prevalent in middle age and later. People who are at risk of a detached retina are severely near-sighted. If you are severely myopic avoid adding pressure to the eye, such as, in scuba diving or skydiving. People who have had previous eye surgeries for a cataract or glaucoma are also at risk of a retinal tear. And people who have had a severe trauma or blow to the head could have a detached retina, as well.
A posterior vitreous detachment precedes a retinal detachment. You’ll see the following symptoms. You’ll see flashes of light in your extreme peripheral vision; a sudden increase in the number of floaters or a ring of floaters; or a slight heaviness in the eye. You’ll also see a gray curtain across your field of vision.
Retinal detachment can sometimes be prevented. Have regular checkups with your doctor. Your optometrist or ophthalmologist can detect in the early stages a retinal tear; then, treat it with laser or cryotherapy.
