Retinal detachment is a condition in which the retina peels off from the underlying supportive tissue. Retina is the innermost layer of the eye which reacts to light and forms images. It is a medical emergency.
SYMPTOMS OF RETINAL DETACHMENT
Retinal detachment itself is painless. But warning signs almost always appear before it occurs or has advanced, such as:
- The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision
- Flashes of light in one or both eyes (photopsia)
- Blurred vision
- Gradually reduced side (peripheral) vision
- A curtain-like shadow over your visual field
CAUSES OF RETINAL DETACHMENT
There are three different types of retinal detachment:
Rhegmatogenous . These types of retinal detachments are the most common. Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, pulling the retina away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.
The most common cause of rhegmatogenous detachment is aging. As you age, the gel-like material that fills the inside of your eye, known as the vitreous (VIT-ree-us), may change in consistency and shrink or become more liquid. Normally, the vitreous separates from the surface of the retina without any complications — a common condition called posterior vitreous detachment (PVD). One complication of this separation is a tear.
As the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. Left untreated, the liquid vitreous can pass through the tear into the space behind the retina, causing the retina to become detached.
- Tractional. This type of detachment can occur when scar tissue grows on the retina's surface, causing the retina to pull away from the back of the eye. Tractional detachment is typically seen in people who have poorly controlled diabetes or other conditions.
- Exudative. In this type of detachment, fluid accumulates beneath the retina, but there are no holes or tears in the retina. Exudative detachment can be caused by age-related macular degeneration, injury to the eye, tumors or inflammatory disorders.
RISK FACTORS OF RETINAL DETACHMENT
The following factors increase your risk of retinal detachment:
- Aging — retinal detachment is more common in people over age 50
- Previous retinal detachment in one eye
- Family history of retinal detachment
- Extreme nearsightedness (myopia)
- Previous eye surgery, such as cataract removal
- Previous severe eye injury
- Previous other eye disease or disorder, including retinoschisis, uveitis or thinning of the peripheral retina (lattice degeneration)
TREATMENT OF RETINAL DETACHMENT
Laser Surgery or freeze treatment known as cryopexy is used to treat retinal detachment. Surgical results are best if the macula (a point in the retina where the light is concentrated and images are formed) is not affected.
