Macular degeneration, also known as age-related macular degeneration (AMD), is a progressive eye condition that affects a tiny part of the retina, called the macula, and can impact retinal health. This condition can cause significant vision loss over time and is one of the leading causes of blindness.
Types of macular degeneration
There are two types of macular degeneration.
Dry AMD is the most common and occurs when the macula gradually thins. Over time, this thinning causes a slow decline in central vision.
Wet AMD is more severe and occurs when abnormal blood vessels grow under the retina, leaking fluid or blood and causing rapid vision loss.
Causes and risk factors
While the exact cause of AMD is unknown, individuals over 50 are more susceptible to developing it. Other risk factors include a family history of AMD, smoking, high blood pressure, and prolonged exposure to UV light.
Common symptoms
Macular degeneration often starts without noticeable symptoms, but as it progresses, you may experience:
- Blurred or distorted central vision
- Difficulty seeing fine details, even up close
- Dark or empty spots in the center of your visual field
- Trouble adjusting to low-light environments
The importance of early detection
If left undiagnosed and untreated, AMD can lead to permanent vision loss, making early detection through regular eye exams and AMD management critical. We recommend annual screenings for those identified as high-risk. Otherwise, an eye exam every two years can help monitor eye health and catch any early signs of this condition.
Diagnosis and treatment
We use specialist equipment like the Optomap retinal screening and Zeiss OCT for both diagnosis and ongoing monitoring of AMD. During your assessment, we’ll evaluate the macula and perform Optomap imaging to capture detailed views of the retina.
If any abnormalities are detected, an OCT scan can be conducted on the same day, allowing the optometrist to decide on the appropriate macular degeneration treatment, such as low vision aids.
If necessary, we can also make an urgent referral to the hospital eye department for further wet and dry AMD care. Each assessment takes about 20 minutes, ensuring prompt diagnosis and management.
