Diagnosis & Treatment
Diagnosis & treatment
The optometrist at True Focus Eye Care in Port Richey can detect early signs of macular degeneration often before symptoms appear. During a comprehensive eye exam, we will conduct several diagnostic tests, including visual field testing and the AdaptDx Pro® test by MacuLogix®.
What is macular degeneration?
Age-related macular degeneration (AMD) is a condition that affects the macula, the central part of the retina responsible for our ability to see fine details and colors. It’s a common eye disease that typically affects older adults, and it can lead to significant vision loss over time. While there’s currently no cure for this condition, early detection and intervention can help slow down the progression of the disease.
What are the different types of AMD?
There are two main types of AMD: dry AMD and wet AMD.
Dry AMD is the more common of the two, and it usually progresses slowly over time. This type occurs when the cells in the macula break down slowly over time. As a result, your vision can become blurry or distorted, and you may notice small yellow deposits called drusen forming in your retina.
Wet AMD is less common than the dry type, but it is considered more serious. It can progress quickly and cause more severe vision loss. In wet AMD, abnormal blood vessels start to grow beneath the retina, and they can leak fluid or blood that causes damage to the macula. This leakage can lead to rapid vision loss. If left untreated, it can cause irreversible damage to your retina and even lead to blindness.
What are the risk factors for AMD?
Age is the biggest risk factor for macular degeneration, and the risk increases significantly after the age of 60. Other risk factors include:
- A family history of the disease
- Certain medical conditions like high blood pressure
- Being Caucasian
- Having light-colored eyes
- Spending long periods outside in the sun without proper eye protection
If you have any of these risk factors, it’s important to schedule regular eye exams with your optometrist and take proactive steps to protect your eye health. The best way to prevent developing macular degeneration is to not smoke, eat a healthy diet, and exercise regularly. Wearing quality sunglasses to block 99%–100% of UV rays also helps protect your eyes.
AdaptDx Pro® test by MacuLogix®
The AdaptDx Pro® test by MacuLogix® measures dark adaptation speed, a key indicator of AMD, up to three years earlier than other tests. Dark adaptation is the number of minutes it takes your vision to adjust to darkness.
During the AdaptDx Pro® test, you’ll wear a headset and press a button whenever you see a flashing light. The result of the test is your Rod Intercept® (RI®), a single number that provides critical information to your doctor. The test only takes about 10 minutes and is completely painless.
After the test, our eye doctor will review the results with you and recommend treatment if necessary. It is usually possible to slow, halt, or even improve night vision loss with supplements, dietary changes, and exercise.
