Age-related Macular Degeneration (AMD): Symptoms, Diagnosis and Treatment Options KEY TAKEAWAYS Age-related Macular Degeneration (AMD) causes a gradual loss of central vision. It is commonly found in people aged 50 and older and is divided into two main types: Dry AMD (most common) and Wet AMD (more severe). Key warning signs include blurry central vision, distorted images, altered colors, or seeing straight lines as wavy or bent. Current treatment technologies include injections (Anti-VEGF), laser therapy to destroy abnormal blood vessels, surgery, and emerging technologies like Gene therapy and Stem cell therapy. Age-related Macular Degeneration (AMD) is a disease caused by the deterioration of cells in the central area of the retina (Macula), which is the most critical part for vision. This leads to a gradual loss of central vision. It may start with blurry central vision, distorted images, or altered colors, eventually leading to a complete loss of central vision. Generally, AMD is commonly found in people aged 50 and older, and the risk increases with age. Other risk factors include smoking, high blood pressure, obesity, and genetics.

It is caused by the accumulation of waste products in the retina, leading to the gradual deterioration of light-sensitive cells and a slow decline in vision. Wet AMD: Less common (about 10-20%) but more severe. It occurs when abnormal new blood vessels grow under the retina. These vessels may leak fluid or blood, causing swelling and scarring in the retina, resulting in rapid vision loss. AMD is the third leading cause of vision loss in the elderly. Although there is currently no complete cure, there are treatment options and new technologies that can slow the progression and maintain the patient's quality of life. What Are the Symptoms of AMD? The symptoms of AMD depend on the stage of the disease. Dry AMD is divided into three stages: early, intermediate, and late. Symptoms typically worsen over time. Early dry AMD usually has no symptoms. In intermediate dry AMD, some people may still have no symptoms, while others may notice mild symptoms such as slight blurring in the center of their vision or difficulty seeing in low light. In late AMD (both wet and dry), many people notice that straight lines start to look wavy or bent. You may notice a blurry area near the center of your vision. Over time, this blurry area may expand, colors may not look as bright as before, and you may have more difficulty seeing in low light. Seeing wavy lines is a key warning sign of late AMD. If you notice this symptom, see an ophthalmologist immediately. How to Reduce the Risk of Age-Related Macular Degeneration? Several studies indicate that adopting the following habits may delay the onset of AMD (or slow down vision loss from AMD): Quit smoking or never start smoking Exercise regularly Maintain healthy blood pressure and cholesterol levels Eat a healthy diet, including leafy greens and fish How Do Ophthalmologists Diagnose AMD? Diagnosis typically involves a comprehensive eye exam, including pupil dilation, retinal examination, and retinal scanning using Optical Coherence Tomography (OCT). AMD Treatment Options 1. Medications and Supplements Vitamins and minerals: Taking vitamins C, E, beta-carotene, zinc, and copper may help slow the progression of dry AMD in some patients. Injections: Anti-VEGF (Vascular Endothelial Growth Factor) drugs are the primary treatment for wet AMD. These drugs help inhibit the growth of abnormal new blood vessels. 2. Laser Therapy Photodynamic therapy (PDT): Uses a laser combined with an injected drug to destroy abnormal new blood vessels. Laser photocoagulation: Uses a laser to directly destroy abnormal new blood vessels. 3. Surgery Blood removal surgery: In cases of severe bleeding in the eye, surgery may be required to remove the blood. Retinal transplant surgery: A new technology that is still in the experimental stage. Pros and Cons of Each Treatment Treatment Method Pros Cons Vitamins and Minerals Inexpensive and safe Not effective for everyone; may have minor side effects Injections Highly effective in treating wet AMD Requires regular injections into the eye; potential side effects Laser Therapy Effective at destroying new blood vessels May damage surrounding normal tissue; not effective for everyone Surgery May help treat certain complications Surgical risks involved; not effective for everyone Consult an Ophthalmologist for an AMD Treatment Plan There are several treatments for AMD, each with its own pros and cons. Choosing the right treatment depends on the type and severity of the disease, as well as the patient's overall health. You should consult an ophthalmologist for the best advice and treatment plan.

Make an Appointment / Consult an Expert โทร 02-511-2111 Line 📅 Book Online Frequently Asked Questions (FAQ) about AMD How many types of AMD are there, and which is more dangerous? It is divided into two main types: Dry AMD, which is the most common and progresses slowly, and Wet AMD, which is less common but much more severe, causing rapid vision loss due to bleeding or fluid leakage under the retina. What does seeing wavy or bent straight lines indicate? Seeing straight lines as distorted, wavy, or bent is a major warning sign of late-stage AMD. If you experience this symptom, you should see an ophthalmologist immediately for proper examination and treatment. Can AMD be completely cured? There is currently no complete cure, but there are treatment options (such as injections and laser therapy) and new technologies that can help slow the progression and preserve the patient's visual quality of life. บทความโดย รศ.นพ. อนันต์ วงศ์ทองศรี ประธานกรรมการบริหาร (CEO) และจักษุแพทย์ผู้เชี่ยวชาญ จักษุแพทย์ผู้เชี่ยวชาญด้านกระจกตาและการผ่าตัดแก้ไขสายตา (LASIK) ประสบการณ์ดูแลคนไข้มากกว่า 100,000 ดวงตา ประวัติแพทย์ นัดหมายปรึกษา *Note: This information is for educational purposes only and cannot replace professional medical diagnosis.

Welcome to our detailed exploration of retinal diseases, specifically focusing on Age-Related Macular Degeneration (AMD), the main cause of vision impairment among older adults. Here at Bangkok Eye Hospital in Thailand, we are dedicated to providing expert care and comprehensive treatment options to manage and potentially mitigate the impact of AMD on your life. Overview of the Retina and Its Function The retina is a critical component of the eye, essential for vision. This thin layer of tissue, located at the back of the eye, captures light and converts it into electrical signals. These signals are sent to the brain, which interprets them as visual images. The retina's functionality is similar to the film in a camera, capturing the world around us and enabling us to see detailed and colorful images.   Understanding Age-Related Macular Degeneration (AMD) Age-Related Macular Degeneration (AMD) is a prevalent retinal condition that primarily affects individuals over the age of 50. It occurs when the central portion of the retina, known as the macula, deteriorates. The macula is responsible for central vision and visual acuity, which is important for tasks such as reading, driving, and recognizing faces.   Types of AMD AMD manifests in two forms: Dry AMD: This is the more common type and is characterized by the thinning of the macula and the presence of drusen, tiny yellow or white deposits on the retina. Dry AMD progresses slowly and gradually impairs central vision. Wet AMD: Less common but more severe, wet AMD occurs when new, abnormal blood vessels grow under the retina, leading to leakage of fluid and blood. This leakage can cause rapid and severe damage to the macula, leading to significant vision loss. Symptoms of AMD The symptoms of AMD can vary but typically include: §  Blurriness in the central part of the vision §  Distorted vision (straight lines appear wavy) §  Difficulty adapting to low light levels §  Decreased intensity or brightness of colors §  A well-defined blurry spot or blind spot in your field of vision   The Impact of AMD on Vision and Lifestyle AMD significantly affects quality of life by impairing the ability to perform everyday activities that require sharp central vision.   “Early detection through regular eye exams is crucial for managing this disease effectively.”   How Bangkok Eye Hospital Can Help At Bangkok Eye Hospital, our approach to managing AMD involves: ü  Early Detection and Regular Monitoring: Utilizing advanced diagnostic tools, we detect AMD in its earliest stages and monitor its progression. ü  Personalized Treatment Plans: Depending on the type and severity of AMD, treatments may include nutritional supplements, laser therapy, and anti-VEGF injections to slow progression and maintain vision. ü  Low Vision Aids and Support: We provide resources and aids to help patients adapt to changes in their vision, ensuring they can continue to enjoy a high quality of life.
