FAQs about Eye Diseases: What is Macular Degeneration?

by

When it comes to eye diseases, most people are familiar with glaucoma and cataracts, but few know about Age-Related Macular Degeneration (AMD).

What is Macular Degeneration?

Age-related macular degeneration (AMD) is an eye disease that directly affects the macula, the small area of the retina that is responsible for central vision. AMD occurs in two forms:

  • Dry Age-Related Macular Degeneration (common): Tiny yellow deposits, called drusen, develop beneath the macula, signaling degeneration and thinning of nerve tissue.
  • Wet Age-Related Macular Degeneration (less common): Abnormal blood vessels grow beneath the macula, leaking blood and fluid onto and underneath the retina. This kills retinal cells, causing blurring, distortion, and blank spots in your field of vision.

Interesting Macular Degenerations Facts & Statistics

  • More than 13 million Americans are affected by AMD.
  • Nearly 90% of all diagnosed AMD is the dry form.
  • About 10% of cases of dry macular degeneration develop into the wet, or neovascular, form of AMD.
  • Globally, AMD is the leading cause of vision loss and is responsible for some 50% of visual impairment.
  • AMD is uncommon in people younger than 55.
  • Women are slightly more likely than men to develop AMD.
  • Studies show that obesity, smoking, and exposure to UV rays may also be risk factors for developing AMD.

Signs and Symptoms of Macular Degeneration

In its early stages, AMD may not present any signs or symptoms. As the eye disease progresses, however, signs and symptoms become much more prevalent and include:

  • The distortion or blurring of central vision
  • Difficulty performing everyday tasks like driving or reading
  • Inability to see small details or fine print
  • Difficulty recognizing faces
  • Need for more light while reading or working
  • Dark or blurry areas in the center of vision (blind spots)
  • Changed color perception
  • Inability to focus properly on a single point within a grid

If you experience any of these signs or symptoms, contact your eye doctor – optometrist or ophthalmologist – at your earliest convenience. The early detection of macular degeneration is critical to the long-term treatment of the eye disease.

Recent innovations in AMD treatment can slow or even halt the progression of retinal changes.

“There are good modern treatments available for patients who lose vision due to AMD,” said board certified ophthalmologist Dr. Cuong Vu of Retina Associates. “[But] early detection and prevention are the keys to success.”

Flashers and Floaters in the Eye: What are They and What do They Mean?

by

As we age, the eye’s gel-like vitreous begins to dissolve and liquefy, creating a watery center. Occasionally some un-dissolved vitreous particles will float around the now watery center, appearing as spots or what we refer to as floaters.

Floaters in the eye are a fairly common, harmless apparition that will generally fade away in time. Yet, while these floaters are typically common, they can be the first signs of a more serious medical condition, such as retinal detachment.

If you ever see a shower of floaters (spots) accompanied by flashes of light (photopsia), then you should seek immediate medical attention. The sudden and dramatic appearance of these symptoms could indicate that the retina is either tearing or detaching.

Retinal detachments and retinal tears are both emergency conditions that require immediate medical attention. An eye surgeon must reattach or repair the retina to prevent permanent vision loss from occurring.

So if you see floaters in your eye, schedule an appointment with your eye doctor – optometrist or ophthalmologist  – at your earliest convenience. Any change in your sight is a serious medical condition that requires prompt attention. If these symptoms appear rapidly and include flashes of light, call your eye doctor right away.

What’s the No. 1 Health-Related Fear Among Americans? Vision Loss

by

Vision LossAccording to a recent study out of the Wilmer Eye Institute at Johns Hopkins University School of Medicine, nearly 50 percent of people (47.4 percent) of the 2,044 U.S. adults polled rated vision loss as the worst possible health outcome, surpassing such other conditions as loss of limb, memory, hearing, or speech. Top concerns among respondents were a diminishing quality of life ranked followed closely by loss of independence. [Read more…]

An Overview of the Different Types of Glaucoma

by

The term Glaucoma actually refers to a group of eye conditions that lead to intraocular pressure (IOP) and damage the optic nerve, the nerve that carries visual information from the eye to the brain. This pressure comes from a buildup of normal fluid called the aqueous humor, which is naturally and continuously produced in the front of your eye.

The different types of glaucoma include:

  • Primary Open-Angle Glaucoma: Affecting around one percent of all Americans (mainly those individuals age 50 or older), it is the most common form of glaucoma. And because this form of glaucoma develops slowly, it rarely ever presents any symptoms and often goes undetected without regular screenings.
  • Normal Tension Glaucoma: Also known as Low-Tension Glaucoma, this form is characterized by progressive optic nerve damage and visual field loss with a statistically normal IOP. The lack of blood flow and the decrease in oxygen to the optic nerve is directly related to this form of glaucoma.
  • Angle-Closure Glaucoma: This form of glaucoma is related to narrow angles. And with several subcategories – including Intermittent and chronic Acute Angle-Closure or Narrow Angle-Closure – this form affects nearly 500,000 Americans, but is most common in people of Asian descent or those individuals with farsightedness (hyperopia). Unlike POAG where the IOP increases gradually, Angle-Closure Glaucoma is characterized by a sudden increase in IOP, often in only a matter of hours. This dramatic increase in IOP can cause severe eye pain, nausea, vomiting, blurry vision and headache. An acute attack is an emergency condition. Long-term effects of Angle-Closure Glaucoma include: scarring of the trabecular meshwork, resulting in chronic glaucoma; cataracts; damage to the optic nerve; permanent vision loss.
  • Pigmentary Glaucoma: This form is a type of inherited open-angle glaucoma, which develops more frequently in men than in women and is most prevalent in individuals in their twenties and thirties. Pigmentary Glaucoma is associated with near-sightedness (myopia).
  • Trauma-Related Glaucoma: A blow to the eye, chemical burn, or penetrating injury may lead to the development of either acute or chronic glaucoma.
  • Childhood Glaucoma: Also referred to as Pediatric Glaucoma, the approach to treatment is slightly different than with glaucoma in adults and almost always requires immediate surgery to relieve IOP. Approximately 80-90 percent of babies who receive prompt surgical treatment, long-term care, and monitoring of their visual development will do well, and may have normal or nearly normal vision for their lifetime. However, if the disease is not caught early more permanent vision loss will result.

The most common symptoms of glaucoma include:

  • Vision loss (most commonly tunnel vision – the gradual loss of peripheral or side vision)
  • Severe eye pain
  • Nausea and vomiting
  • Sudden onset of visual disturbance
  • Blurred or blurry vision
  • Halos around lights
  • Reddening of the eye

If you feel you may be experiencing any of these symptoms, schedule an appointment with your eye doctor immediately. These symptoms are serious and require prompt medical attention from your optometrist or ophthalmologist.

However, many people do not experience any symptoms until they begin to lose their vision. At this point, the damage is irreversible. This is why regular eye exams are so important. While there is no cure for glaucoma, early detection and treatment are your best options to slow or even prevent further vision loss brought on by the disease. Without treatment, glaucoma can lead to permanent vision loss.

Glaucoma is the second-leading cause of vision loss in the United States behind only cataracts.

What is the Best Way to Prevent Vision Loss Due to Glaucoma?

by

Glaucoma is a well-known eye condition that is not well known. Wait, what? What we mean by this is that while most people have heard of glaucoma, many do not know much about this eye condition, or more accurately a group of eye conditions. According to a 2002 survey by Prevent Blindness America, an astonishing 80% of respondents had no idea what glaucoma was.

What is Glaucoma?

There are many forms of glaucoma (as many as 70-80). Most stem from increased intraocular pressure (IOP), or outside factors, such as trauma or disease, and damage the optic nerve, which is responsible for carrying visual signals to the brain.

Vision Loss Glaucoma

At first, vision loss due to glaucoma is almost unnoticeable. There are no warning signs, no symptoms.

Normal eye pressure is 12-21 mm Hg. Anything above 21 is considered elevated.

What is the Best Way to Prevent Vision Loss Due to Glaucoma?

Currently, there are 60 million people worldwide (2.2 million Americans) afflicted with glaucoma. What’s scarier is that roughly half of those people – nearly 30 million people – don’t even know they have glaucoma. How is this possible? At first, vision loss due to glaucoma is almost unnoticeable. There are no warning signs, no symptoms. As a result, a person can lose as much as 40% of his or her vision before they even notice a difference.

So what is the best way to prevent such vision loss? Regularly Scheduled Eye Exams. Only a compressive eye exam, including tonometry, visual field exam, visual acuity, and a dilated eye exam can determine if glaucoma is present.

If caught early and treated properly, vision loss due to glaucoma can be stopped 95% of the time. When was your last eye exam?
