Retinal Conditions and Diseases
The most common diabetic eye disease occurs when blood vessels in the retina change. Sometimes these vessels swell and leak fluid or even close off completely. In other cases, abnormal new blood vessels grow on the surface of the retina.
Macular degeneration (AMD) is caused by deterioration of the retina and can severely impair vision. There is no cure for macular degeneration, but it can be treated with vitamins, laser therapy, medications, and vision aids.
Retinal detachment is a very serious condition that occurs when the retina separates from its underlying tissues. Since the retina can't work properly under these conditions, permanent vision loss may occur if a detachment is not repaired promptly.
Flashes and Floaters
You may sometimes see small specks or clouds moving in your field of vision. These are called floaters. When the vitreous gel pulls on the retina, you may see what looks like flashing lights or lightning streaks. These are called flashes.
A macular hole is a small break in the macula, the part of your eye responsible for detailed, central vision.
Retinal Vein Occlusion
Central retinal vein occlusion (CRVO) is a blockage of the main vein in the retina. The blockage causes the walls of the vein to leak blood and excess fluid into the retina. When this fluid collects in the macula, vision becomes blurry.
A macular pucker (also called an epiretinal membrane) is a layer of scar tissue that grows on the surface of the retina, particularly the macula, which is the part of your eye responsible for detailed, central vision.
Uveitis is basically an internal inflammation of the eye. The condition involves the middle layers of the eye, also called the uveal tract or uvea. The uvea includes the iris (colored part of the eye), choroid (a thin membrane containing many blood vessels), and the ciliary body (the part of the eye that joins these together). The uvea is very important because its many veins and arteries transport blood to the parts of the eye that are critical for vision.
What Are the Symptoms of Uveitis?
Symptoms of uveitis may include eye redness and irritation, blurred vision, eye pain, increased sensitivity to light, floating spots before the eyes.
What Causes Uveitis?
Uveitis has many potential causes, including infection with a virus. Other potential causes include fungus, bacteria, parasite, inflammatory disease affecting other parts of the body, or injury to the eye.
How Is Uveitis Treated?
Because uveitis is serious, treatment needs to begin right away. For uveitis not caused by an infection, your eye specialist may prescribe eye drops containing steroids to reduce swelling and drugs to relieve pain. Antibiotics are used in patients with infectious uveitis. Dark glasses will help with light sensitivity.
Ocular melanoma (melanoma in or around the eye) is a type of cancer that develops in the cells that produce pigment. Just as you can develop melanoma on your skin, you can also develop it in your eye.
Ocular Trauma can occur in various ways, you should seek immediate medical attention in case of any emergency.
