What is retina?
Retina
is the innermost and the most important layer of the eye. It is similar to the
film of a camera. It converts light into images for the brain to see. It is loosely
glued to the wall of the eye. What is retinal detachment?
When this
glue weakens, the retina separates from the wall of the eye. The retina now does
not work and the vision falls. It is a very serious problem that almost always
causes blindness if untreated. Early treatment has better outcome. How
does it occur?
Most occur due to holes, tears, breaks or degenerations
in the retina, but all do not lead to detachment. Some occur due to inflammations,
diabetes, tumors or other diseases. Vitreous gel, which fills the inner part of
the eye then seeps through these holes and lifts the retina. Who are
at higher risk?
Myopia (nearsightedness, minus spectacles).
Previous cataract surgery. Previous retinal detachment in other eye. Family
history of retinal detachment. Severe injury. Weak areas in the retina.
1 in 10,000 people are likely to get it. What are the symptoms?
Flashes of light.Floaters (black spots) in front of eyes.Shadow
moving across the eye.Sudden drop or crooked vision.
These
symptoms are never painful.
