Age-Related Macular Degeneration? " Betty a 75-year-old female with sudden onset of central vision loss in her right eye "

Case study ( 13031 views as of November 21, 2024 )

Betty, a 75-year-old female, presents with sudden onset of central vision loss in her right eye. She has had ‘perfect’ vision since her cataract surgery 15 years ago. The vision loss has affected her ability to thread needles and read small print. Her sister, a heavy smoker, lost vision in her late 60s due to age-related macular degeneration. When she covers her good eye she cannot see the face of someone in front of her. The entire central vision is a grey-blank. Her peripheral vision, however, is entirely unaffected. She worries that she will go completely blind and lose her ability to live independently.

Betty is referred to a retina specialist, who diagnoses her with wet age-related macular degeneration. Injection treatments are recommended. These are administered on a monthly basis and allow for a significant improvement in acuity.

Working with her comprehensive ophthalmologist and occupational therapist, Betty begins using magnifiers and new software on her computer to allow her to sew and read more easily. She still has some persistent vision loss, but is able to continue doing the many detailed visual tasks that were not possible at the time of her initial vision loss.

For dry macular degeneration, antioxidant vitamins are commonly used for management. The specific formulation recommended by the National Institute of Health (NIH) includes Vitamin C and E, zinc (with copper supplementation to prevent anemia), and lutein or zeaxanthin, which are carotenoids that protect the macula. It is important to note that the decision to start these vitamins should be made by an ophthalmologist based on evidence of macular degeneration, as not all patients may benefit from them. Taking the recommended vitamins can reduce the risk of macular degeneration by approximately 30% over a period of five to seven years. In the case of wet macular degeneration, the treatment involves injections of anti-VEGF (vascular endothelial growth factor) chemicals into the back of the eye. This treatment has shown significant improvement in vision outcomes compared to previous methods. The injections are performed every month to two months and are relatively painless. The ophthalmologist administers local anesthesia and ensures proper eye hygiene to reduce the risk of infection. Typically, the treatment is required for up to two years, and additional treatments may be necessary depending on the individual's condition. By undergoing this treatment, the likelihood of vision loss is significantly reduced, allowing most individuals to maintain their vision for many years. However, early detection and prompt treatment are crucial, as delaying diagnosis and treatment can lead to irreversible scarring and diminished treatment effectiveness. It is emphasized that the sooner macular degeneration is diagnosed and treated, the better the chances of limiting the damage and preserving vision. While immediate treatment after the onset of the disease is not always possible, it is recommended to seek treatment within a few days of a wet macular degeneration diagnosis. If you have further questions about the treatment of macular degeneration, it is advisable to consult with your family doctor or local ophthalmologist.

Well the management of macular degeneration involves a few different steps. The first thing we can talk about once you’ve been diagnosed with macular degeneration is prevention. And the easiest thing to do is, if you’re a smoker, is to do whatever you can to reduce your smoking and eliminate it. Because that’s a big trigger for a lot of macular degeneration. There may also be a role to wearing light protection for UV and bright light that wouldn’t hurt in the setting of macular degeneration. Now there’s another piece in terms of early detection, and the early detection of macular degeneration is essential because the sooner a patient is diagnosed with the disease, especially in the form of wet macular degeneration, the sooner the treatment can be initiated, and the better the visual outcomes. And there’s a number of ways you can test your eyes at home to be sure that you’re hopefully not developing macular degeneration that’s progressive. The first of those is called an Amsler grid, which is a grid paper, much like a piece of graph paper, that you can look at and look for areas where the lines start to become wobbly or distorted, or perhaps the lines are even missing. And that’s a very simple test that you can even do. You can look for an Amsler grid on the Internet and find a version of that and test that on your own computer every day. The second type of testing is a home monitoring device that are starting to become available throughout North America, where it’s almost like a small computer device you would keep at home, and it can help you to diagnose early macular degeneration as well. Or simply just paying attention to your reading or any fine, detailed work you do with your eyes. If you start to lose letters when you’re reading or you notice lines, for example, straight lines, doorways, start to become bumpy or wobbly in the middle. Those would be good signs to get your eyes examined to make sure that nothing’s going on.

Macular degeneration is primarily considered a genetic disease, and this understanding has evolved over the past decade or two. Much of the risk for macular degeneration is determined by your genetic makeup and is already predetermined at birth, which means there are limited preventive measures that can be taken. However, certain behavioral factors such as smoking and excessive exposure to sunlight or UV rays may modify the genes associated with macular degeneration and increase the risk for certain types of the disease. It is important to be aware of these factors and take necessary precautions. If you have a strong family history of macular degeneration and want more information about your genetic risk factors, there are tests available to assess those risks. To diagnose macular degeneration, it is necessary to visit an ophthalmologist for an assessment. This typically involves dilating your pupils using drops. It is important to arrange for someone to drive you home after the assessment and consider bringing sunglasses for comfort. During the assessment, the ophthalmologist will carefully examine your eyes, looking for any changes, hemorrhaging, or other concerning signs of macular degeneration. Based on the findings, further tests may be conducted to confirm the diagnosis. The most common and traditional test is called a fluorescein angiogram, where a dye is injected into your arm, and photographs are taken of your eyes to examine blood flow and details of the back of the eye. Additionally, an optical coherence tomograph may be used to provide detailed laser images of the layers in the back of the eye. A more recent test called an auto-fluorescence test, which involves a bright blue flash of light, can assess the health of the pigment layers under the retina, aid in the diagnosis of dry macular degeneration, and provide information about disease progression. Following the assessment and initial examination, your physician will have a good understanding of whether further testing is necessary. In many cases, the additional tests can be conducted and interpreted on the same day, and treatment can be initiated promptly, depending on the logistics of the specific clinic. If you have more questions or concerns about the diagnosis or causes of macular degeneration, it is advisable to consult your family physician. If they are unable to provide all the answers, your local ophthalmologist will be able to provide further information and guidance.

Generally when you hear of people losing their vision it begins in the periphery and spreads in. Why with macular degeneration does it begin in the center?

A lot of patients come in complaining that they may have pink eye. In general, pink eye refers to a viral infection of the conjuctiva. Now, your conjunctiva is the mucus membrane that covers the surface of your eye, right up to your iris or your cornea there, and it can get inflamed for a number of reasons.

Macular degeneration runs in our family. I think it is more common in people with lighter (blue?) eyes. I wonder about the vitamins recommended for eye health, if they actually work.
