Conditions

Regular eye examinations by an ophthalmologist (Eye M.D.) are the best way to detect eye conditions early, while they can be treated. An ophthalmologist is a medical doctor (M.D. or D.O.) with special training and skills to diagnose and treat all diseases and disorders of the eye.

The following are eye problems commonly experienced by older people.

PRESBYOPIA

As you grow older, your lens becomes less flexible. By about age 40, the lens cannot change shape as easily as it once did, and it becomes more difficult to read. This normal condition is called presbyopia.

FLOATERS

You may sometimes see small specks or clouds moving in your field of vision. They are called floaters. You can often see them when looking at a plain background, like a blank wall or blue sky.

Floaters are actually tiny clumps of gel or cells inside the vitreous, the clear, gel-like fluid that fills the inside of the eye.

You should contact your ophthalmologist right away if you suddenly develop new floaters. These symptoms may indicate a torn retina, which could lead to a retinal detachment.

CATARACT

Cataract is a clouding of the eye’s naturally clear lens, like a window that is fogged with steam. When the lens becomes cloudy, light rays cannot pass through it easily, and vision becomes blurred.

Protecting your eyes from sunlight may slow the progression of cataracts. There are no medications, eye drops, or exercises or eyeglasses that will cause cataracts to disappear once they have formed. Surgery is the only way to remove a cataract.

Common Cataract Symptoms:

  • A painless blurring of vision
  • Glare or light sensitivity
  • Poor night vision
  • Needing brighter light to read
  • Fading or yellowing of colors

It is up to you to decide when to have a cataract removed. When you are unable to see well enough to do the things you like or need to do, you should consider cataract surgery.

In cataract surgery, the cloudy lens is removed through a small surgical incision. IN most cases, the focusing power of the natural lens is restored by replacing it with a permanent intraocular lens (IOL) implant.

Cataract surgery improves vision in most cases. Cataract surgery is usually done on an outpatient basis so you can go home the next day.

GLAUCOMA

Glaucoma can damage nerve fibers, causing blind spots in our vision.

Glaucoma can affect the pressure inside the eye, or intraocular pressure (IOP).

Your ophthalmologist can determine if you have glaucoma after examining the pressure in your eye, your optic nerve, and your peripheral (side) vision.

MACULAR DEGENERATION

Macular degeneration is damage or breakdown of the macula of the eye. The macula is the small, central area of the retina that allows us to see fine details clearly. Macular degeneration is caused by aging and thinning of the tissues of the macula. Vision loss is usually gradual.

In some cases, abnormal blood vessels develop and leak fluid or blood under the
macula. Vision loss in this case may be rapid.

If you experience one or more of the following symptoms, have your eyes examined promptly:

  • Words on a page look blurred in the center
  • Straight lines look distorted, especially toward the center of your vision.
  • A dark or empty area appears in the center of vision
  • Colors look dim

There is no proven cure for macular degeneration. In some people who have leaking blood vessels, laser surgery may slow or prevent additional vision loss.

DIABETIC EYE PROBLEMS

Diabetes can cause changes in the veins and arteries that carry blood throughout your body. This disease can affect your vision by causing cataracts, glaucoma, and, most important, damage to blood vessels inside the eye.
When blood vessels in the retina are damaged, they may leak fluid or blood and grow fragile, brush-like branches and scar tissue. This condition, called diabetic retinopathy, can blur or distort the images that the retina sends to the brain.

You can have serious, sight-threatening retinopathy without any symptoms. The best protection against loss of vision from diabetic retinopathy is to have regular eye examinations by your ophthalmologist. People with diabetes should have eye examinations at least once a year, or as recommended by your ophthalmologist.

BLEPHARITIS

Blepharitis is an inflammation of the eyelids. The membrane covering the inside of the eyelid and the white of the eye may also become inflamed. Blepharitis can be caused by bacteria (germs) on the eyelids or on the skin around the eyes. Dandruff or oily skin can also cause blepharitis. Wearing contact lenses or makeup can make the symptoms worse. Blepharitis can’t always be cured. But it can be controlled.

DRY EYE

Some people do not produce enough tears or the appropriate quality of tears to keep the eye healthy and comfortable. This is known as dry eye.

What are the symptoms of dry eye?

The usual symptoms include

  • Stinging or burning eyes
  • Scratchiness
  • Stringy mucus in or around the eyes
  • Excessive eye irritation from smoke or wind
  • Excess tearing
  • Difficulty wearing contact lenses

Excess tearing from “dry eye” sounds illogical, but if the tears responsible for maintenance lubrication do not keep the eyes wet enough, the eye becomes irritated. When the eye is irritated, the lacrimal gland produces a large volume of tears that overwhelm the tear drainage system. These excess tears then overflow from your eye.

MEDICAL BOTOX

Despite its fame as a cosmetic treatment, BOTOX can be used to treat medical conditions as well.  Two eye conditions approved for this type of treatment include blepharospasm (eyelid spasms), and strabismus (crossed eyes)

Blepharospasm causes spasms in and around the eyelids, resulting in frequent and uncontrollable blinking and closing of the eyes. Treatment with BOTOX® can reduce these muscle spasms, which reduces blinking, which may help restore the ability to see.

Crossed eyes happen when certain muscles tighten around the eye, which can pull the eyeball to the side. BOTOX® treatment can relax the affected muscles allowing the eyeball to return to its normal position.
