Eye Care, Man with Macular Degeneration in Dallas,TX.

Macular degeneration is the leading cause of irreversible severe vision loss and blindness.

By 2050, it is projected that the incidence of diagnosed macular degeneration will double to 22 million. The prevalence of this disease may be more than we know. Recent reports reveal that approximately 25% of patients after having a dilated eye examination had macular degeneration that was undiagnosed.

Sadly, by the time patients are diagnosed with macular degeneration, 78% have already suffered irreversible vision loss. Early detection of macular degeneration through a reliable eye care center with the latest diagnostic tools is essential to retaining healthy vision.

Texas Macular Degeneration Associates, Inc.

adaptdxin coordination with the Eye Doctor’s Office offers the most advanced testing tool for early detection of macular degeneration: the AdaptDx.

We are proud to be among the first eye care practices in North Texas who have access to this new diagnostic technology. We can detect signs of this dreadful disease up to three years earlier when compared to a routine eye examination.

In addition to our technology, our optometrists, Dr. Bob Consor and Dr. Jennifer Nguyen, are part of a team of affiliated off site ophthalmologists and retinal specialists associated with:

  • Texas Retina Associates,
  • The Retina Foundation of the Southwest Dallas Texas

Through our affiliation, we provide our patients with the most comprehensive eye exam utilizing the latest in eye care technology for the detection, management, and treatment of macular degeneration.

Earlier detection of this very serious eye disease means earlier treatment, better patient outcomes and prevention of visual acuity loss.

Early Detection Benefits Patients of Any Age

Although macular degeneration is more common in patients above the age of 50, the disease can occur in younger patients. Not only can the AdaptDx detect early signs of macular detection, we can further evaluate each of our patients risk factor for the disease with new advances in genetic testing. We've developed treatment plans in the form of nutritional supplements and lifestyle changes to minimize the effects of macular degeneration, improve the quality of one’s life, and preserve their vision.

What are the early signs of Macular Degeneration?

Macular degeneration causes loss of central vision and if not detected early can lead to permanent visual impairment and blindness. It is a major health problem and is more prevalent than glaucoma and diabetic retinopathy combined.

Today eye doctors are missing macular degeneration 25% of the time even in a dilated eye examination. By the time its structurally detected in an examination, 78% of those patients have already suffered irreversible vision loss in one eye, and nearly half of them are legally blind with 20/200 vision in one or both eyes.

Texas Macular Degeneration Associates is one of the first in the United States and the first in Dallas, Texas to have the AdaptDx technology that detects macular degeneration up to three years before it shows up in a routine eye examination.

We are passionate in saving sight and preventing blindness. Our team of eye doctors invest in the latest technology and participate in continuing education. Through our commitment and expertise, we have formed a center of excellence for macular degeneration detection and management.

We’re proud to provide our patients with the leading diagnostic test for macular degeneration — the AdaptDX.

The AdaptDx measures your ability to adjust from bright light to darkness. That period of time is called dark adaptation. Impaired prolonged dark adaptation is a biomarker of this disease. Symptoms that might be early signs of macular degeneration are difficulty in seeing at night or reading in dim illumination.

The AdaptDx backed by years of research and medical evidence. In clinical studies involving more than 1,000 patients, AdaptDx has proven to be 90% sensitive and 90% specific for the presence of macular degeneration. The clinical studies were conducted at renowned research centers, such as Harvard University, Duke University, the National Eye Institute, and the University of Alabama at Birmingham.

Fast & Effective: AdaptDx Technology

The test takes up to six minutes per eye.

First, your eyes are exposed to normal illumination. Then, you look into the AdaptDx which simulates a dark environment. You are finally asked to recognize light stimuli at various intensities using a handheld response button. The test is non-invasive.

The entire test is conducted in a darkened room with the patient’s chin and forehead resting on comfortable supports similar to those on other eye care instruments.

What Does This Test Feel Like?

Just imagine going to the movies on a bright sunny day. As you leave the sunny outdoors and enter the dark theater, your vision slowly adapts to the darkness of the theater. That’s called dark adaptation.

However, macular degeneration impairs this process, which is referred to as impaired dark adaptation. The recovery time for your vision to transition from daylight to darkness is the only biomarker of age-related macular degeneration and is one of the earliest symptoms of macular degeneration that can be detected.

In clinical studies involving more than 1,000 patients, AdaptDx has proven to be 90% sensitive and 90% specific for the presence of macular degeneration. The clinical studies were conducted at renowned research centers, such as Harvard University, Duke University, the National Eye Institute, and the University of Alabama at Birmingham.

Since our office has begun using the AdaptDx we have been able to identify macular degeneration in a much larger percentage of our patient base then we were diagnosing before. This might bring up some questions like; “What can you do to help these patients? Why waste your time on a disease that is not curable?”

The answer to those questions is; early detection of macular degeneration matters and it’s a disservice to a patient not to treat and manage this disease early. Although there is currently no cure for this disease, there are many things that can be done to protect patients from avoidable vision loss. Lifestyle changes can have an enormous impact for patients at any stage of macular degeneration including periodic follow up visits with additional and comparative testing to monitor and measure the results of the treatment. During these visits the patient’s compliance is accessed and we become the advocate and coach. Even the empowered patient that finds out they have macular degeneration is no different than anyone else and can go into denial and become complacent with the treatment plan for their condition.

What Are Some of the Lifestyle Changes That Can Be Made

  • If you smoke, try to stop.
  • Stay away from secondary smoke.
  • Exercise 5 days a week for 30 minutes. Even walking around the block is fine.
  • Eat greens and a rainbow of colors of fruits and vegetables.
  • Take a multivitamin and vitamin eye supplements.
  • Wear sunglasses outdoors.
  • Maintain a normal weight for your body style.
  • Maintain your blood pressure.
  • Control your cholesterol level.
  • Get an eye examination every year or more often if instructed.
  • Return as directed for your periodic macular degeneration follow-up visits.

Texas macular Degeneration Associates has the technology, knowledge, experience and skills to determine if a patient has the early signs of macular degeneration. Testing for impaired dark adaptation takes the guess work out of the diagnosis, empowers the patient with knowledge and gives a clear answer that illuminates a treatment plan for the patient.

Patients with impaired dark adaptation are two times more likely to develop macular degeneration within three years of detection that they have impaired dark adaptation. It’s worth mentioning, many of these patient have no symptoms in the early stage of the disease. The AdaptDx finds sub-clinical (before it’s detected in an eye examination) macular degeneration by measuring a patients time to adapt from light to dark. Impaired dark adaptation is sub-clinical meaning it is happening functionally at the cellular level years before it shows up on an eye examination clinically as structural (visible to the eye doctor) tissue changes.

The goal of management and treatment of macular degeneration is to prevent progression to advanced disease and preserve sight allowing patients to enjoy additional years of high quality central vision.

Who Should Be Concerned About Macular Degeneration

We feel that everybody should be concerned and aware of the risks and methods to prevent macular degeneration, especially:

AdaptDx should be performed on patients who:

  • Have a family history of macular degeneration
  • Have problems with night vision or vision in low light environments
  • Have problems reading in dim light
  • Smoke, have smoked in the past or have been exposed to a lot of secondary smoke
  • Are obese
  • Are inactive and have poor dietary intake(lacking fruits, vegetables and vitamins)
  • Don’t wear sunglasses
  • On an exam have visible structural yellow spots on the macula called drusen (by this time the disease has been around for many years).
  • Who have uncontrolled high blood pressure, heart problems and or elevated cholesterol

Today eye doctors are missing macular degeneration 25% of the time in an a dilated eye examination and by the time its structurally detected and diagnosed and detected 78% of those patients have already suffered irreversible vision loss in one eye and nearly half of them are legally blind with 20/200 vision in one or both eyes.

You might be asking;

What purpose does this test have if you can’t stop it or can’t cure it?’”

Here are some reasons:

  1. Finding out a patient has macular degeneration early empowers the patient with knowledge and prepares them to make changes I n their life now that can slow the disease down or at least prepare the patient for vision loss in the future so they can adjust their life plans. Finding out that you need to battle a serious condition for the rest of your life is a hard pill to swallow. But early detection with the appropriate lifestyle changes can mean the difference as the disease progresses between becoming legally blind (best corrected visual acuity 20/200) and much better best corrected vision.
  2. Monitoring the patient with at risk suspected macular degeneration or early subclinical macular degeneration every 3-6 months allows for detection of changes related to progression of the disease. At this point, adjustments in the treatment plan can be made by the doctor in addition to coaching the patient to become more compliant in their treatment plan. Let’s face it as human beings we are inherently lazy and most patients are less than perfect in following doctor’s orders.
  3. Follow up care is not only important for the detection of changes before further vision loss occurs but those visits with the doctor and the staff function like a coaching session giving the patient encouragement and preventing them from feeling alone and frightened. Ultimately an informed patient will take more ownership of his or her wellness.
  4. Macular degeneration is frightening disease; ask any patient who has been diagnosed with it. It’s like a death sentence and the fear of going blind is unimaginable to one who doesn’t have it. Fact is the number one fear people have is going blind.
  5. Most macular degeneration is dry but 15-20% advance to a more serious level called wet macular degeneration. The earlier the wet form of the disease is detected the better chances minimizing vision loss. A finding of a choroidal neovascular membrane (CNV)) requires immediate treatment and surgical intervention.

Frequently Asked Questions about Macular Degeneration

What is the connection between macular degeneration and dark adaptation?

When the cells in the macula become functionally sick and compromised clinical research has shown it has an effect on the eyes ability to dark adapt and is the first biomarker of subclinical macular degeneration years before it shows up in the eye as physical structural changes.

What do you mean by functional and physically structural?

A few functions of a cell are to transport substances, produce energy, reproduce and facilitate growth. When a cell becomes sick it can no longer function. Once that happens it takes time as in the case of the macula years later for structural changes take place in the macula that can be observed in a routine eye examination but by that time a lot of damage has taken place

What is subclinical macular degeneration?

This is the earliest stage of the disease; the functional stage with minimal to no vision loss and undetectable by the eye doctor a routine dilated eye examination. At this point macular degeneration has already impaired the function of the macula, specifically dark adaptation. The time to find macular degeneration is in the subclinical stage.

How is dark adaptation testing different from other tests to find macular degeneration?

Other available tests look at the structure of the macula or risk factors for macular degeneration. The AdaptDx is the only instrument the measures the integrity of the cellular function of the macula.

A friend of mine told me her doctor measures the pigment in the macula to detect the disease. What that all about?

She must be referring to the MPOD (macular pigment optical density). Although a risk factor for macular degeneration it’s not a physiological indicator of the disease and research has shown that there is no correlation between macular pigment density and impaired dark adaptation.

How accurate is dark adaptation with the AdaptDx

The AdaptDx is 90% sensitive in identifying macular degeneration and normal eyes.

Currently, there is no cure for Macular Degeneration (MD)

The management of MD has two primary goals

  • Preserving vision preventing progression to more advanced MD
  • Effectively detecting and managing wet MD (Choroidal Neovascular Membranes)
    Achieving these goals will allow the patient to enjoy additional years of high-quality central vision, enhancing the odds of a better quality of life. Since people are living longer early diagnosis and consistent, aggressive management of the disease is required to minimize risk of vision loss.
    The importance of following your doctor’s orders to return for follow up care and monitoring cannot be overstated. The management of macular degeneration by your eye doctor is crucial to maintaining and prevention of permanent vision loss.
