Causes of macular edema
Even as the word retina has become commonplace. The macula and its diseases are often misunderstood. The retina is the light-sensitive layer of cells that lines the inside of the eye.
The many layers of the retina work together to ทางเข้า ufabet convert light focused on the retina into an exquisitely detailed message that travels to the visual cortex in the brain. There, the message is decode and directs us to take action “that’s a fine looking piece of pie!”
The macula is the part of the retina that helps us see fine detail, faraway objects, and color. It’s pack with more photoreceptors (light-sensitive cells) than any TV or monitor. The small, central area of the retina is worth the most the bullseye of sight, degeneration, hole, pucker, drusen (small yellowish deposits), scar, fibrosis, hemorrhage, and vitreomacular traction are common conditions that involve the macula. When macular disease is present, distorted vision (metamorphopsia), blank spots (scotoma), and blurred vision are common symptoms.
How to treat macular edema
The treatment approach is to control risk factors such as:
- Use of steroids
- Try to reduce and avoid stress.
- In cases where some patients have a smoking habit, they should reduce their smoking.
Most patients, 80-90%, will be able to regain normal vision under the care of an ophthalmologist.
Types of Diabetic Macular Edema
There are two key types of diabetic macular edema:
- Non-central-involved diabetic (mild)
- Central-involved diabetic (severe)
Both types are characterize by thickening of the retina that is 1 millimeter in diameter or larger. In non-central-involved diabetic the thickening doesn’t involve the central subfield zone of the macula. The central subfield is the 1 mm area around the center point of the fovea, a small depression in your macula where your vision is sharpest.
