You can still see everything around it, but what you look at directly fades away. For many people, this is how <strong>age-related macular degeneration (AMD)<\/strong> begins. And here is the key point: in its early stages it <strong>causes no pain and almost no symptoms<\/strong>, so it is best not to wait until your vision gets worse to have it checked.<\/p>\n<p class=\"wp-block-paragraph\">At <strong><a href=\"https:\/\/ramirezgalvez.com\/en\/our-clinics\/\">Ram\u00edrez &amp; G\u00e1lvez Clinic<\/a><\/strong> we explain what <a href=\"https:\/\/ramirezgalvez.com\/en\/eye-problems\/age-related-macular-degeneration-amd\/\">macular degeneration<\/a> is, how to recognise the warning signs, what you can check yourself at home and which treatments are available today.<\/p>\n<h2 class='wp-block-heading'><strong>What is macular degeneration and why does it affect what you look at directly? \ud83c\udfaf<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">The <strong>macula<\/strong> is a tiny area at the centre of the retina, only a few millimetres across, but essential: it is responsible for <strong>detailed vision<\/strong>. It lets you read, recognise faces, drive, sew or look at your phone. AMD is the gradual wearing down of this area.<\/p>\n<p class=\"wp-block-paragraph\">A reassuring fact: <strong>AMD does not cause total blindness<\/strong>. Peripheral vision, which helps you move around and find your way, is preserved. What deteriorates is central vision, and AMD is one of the leading causes of central vision loss after the age of 55.<\/p>\n<figure style='margin:1.5em 0;text-align:center'><svg xmlns='http:\/\/www.w3.org\/2000\/svg' viewBox='0 0 640 260' style='max-width:100%;height:auto' role='img' aria-label='The same scene seen with normal vision and with macular degeneration: a dark patch covers the centre of the image'><defs><linearGradient id='dm-sky' x1='0' y1='0' x2='0' y2='1'><stop offset='0' stop-color='#bfe0f2'\/><stop offset='1' stop-color='#fdf1d6'\/><\/linearGradient><radialGradient id='dm-spot'><stop offset='0' stop-color='#262626' stop-opacity='.95'\/><stop offset='.65' stop-color='#4a4a4a' stop-opacity='.75'\/><stop offset='1' stop-color='#6a6a6a' stop-opacity='0'\/><\/radialGradient><clipPath id='dm-c'><rect width='300' height='200' rx='14'\/><\/clipPath><g id='dm-scene' clip-path='url(#dm-c)'><rect width='300' height='200' fill='url(#dm-sky)'\/><circle cx='230' cy='50' r='24' fill='#f6c453'\/><path d='M0,150 Q70,95 140,140 T300,120 V200 H0Z' fill='#7fae7a'\/><path d='M0,178 Q90,140 180,170 T300,160 V200 H0Z' fill='#5d9360'\/><rect x='128' y='112' width='44' height='34' fill='#d8b48c'\/><path d='M120,114 L150,88 L180,114Z' fill='#a35d4a'\/><rect x='144' y='126' width='12' height='20' fill='#7a4a38'\/><\/g><\/defs><use href='#dm-scene' x='10' y='10'\/><g transform='translate(330,10)'><use href='#dm-scene'\/><ellipse cx='150' cy='105' rx='64' ry='60' fill='url(#dm-spot)'\/><\/g><text x='160' y='240' font-family='Arial,Helvetica,sans-serif' font-size='17' font-weight='700' fill='#1f3a4d' text-anchor='middle'>Normal vision<\/text><text x='480' y='240' font-family='Arial,Helvetica,sans-serif' font-size='17' font-weight='700' fill='#1f3a4d' text-anchor='middle'>With AMD: central blind spot<\/text><\/svg><figcaption style='font-size:15px;margin-top:8px'>AMD darkens or distorts the centre of the image and spares the edges (illustrative drawing).<\/figcaption><\/figure>\n<h2 class='wp-block-heading'><strong>Dry AMD and wet AMD: two forms, two speeds \ud83d\udd2c<\/strong><\/h2>\n<ul class='wp-block-list'><li><strong>Dry AMD (atrophic):<\/strong> the most common form, around 9 out of 10 cases.

The ophthalmologist examines the <strong>back of the eye<\/strong> with dilated pupils to see the macula and, depending on the case, may complete the assessment with <strong>imaging tests<\/strong> such as optical coherence tomography (OCT), which gives a detailed \u201cslice\u201d of the retina. In some cases other tests are needed to confirm whether abnormal vessels are present.<\/p>\n<h2 class='wp-block-heading'><strong>Treatment: what can be done today \ud83d\udc89<\/strong><\/h2>\n<h3 class='wp-block-heading'><strong>In dry AMD<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">There is currently no treatment that reverses the wear, but its progression can be <strong>slowed down<\/strong> and useful vision preserved for longer: stop smoking, look after your diet, protect your eyes from the sun and keep blood pressure and cholesterol under control. In intermediate or advanced stages, the ophthalmologist may prescribe <strong>specific antioxidant supplements<\/strong>. Don&#8217;t self-medicate: they only help when they are indicated for your case.<\/p>\n<h3 class='wp-block-heading'><strong>In wet AMD<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">The usual treatment is <strong>intravitreal injections of anti-angiogenic drugs<\/strong>, which slow the growth of abnormal vessels and reduce leakage. They are given regularly, under local anaesthesia, and require close follow-up. The aim is to <strong>stabilise vision and prevent it from worsening<\/strong>; the sooner treatment starts, the better the outlook, although results vary from person to person.<\/p>\n<p class=\"wp-block-paragraph\">And if central vision is already affected, there are <strong>visual aids and low-vision rehabilitation<\/strong> (magnifiers, filters, lighting, electronic aids) that restore independence in daily life.<\/p>\n<h2 class='wp-block-heading'><strong>How to look after your macula every day \ud83e\udd57<\/strong><\/h2>\n<ul class='wp-block-list'><li><strong>Don&#8217;t smoke<\/strong> (and if you do, quitting is the best thing you can do for your eyes).<\/li>\n<li><strong>Eat a varied diet:<\/strong> leafy green vegetables, fruit, oily fish and nuts, in the style of the Mediterranean diet.<\/li>\n<li><strong>Protect your eyes from the sun<\/strong> with approved UV-filtering sunglasses.<\/li>\n<li><strong>Keep blood pressure, cholesterol and glucose under control<\/strong> and stay active.<\/li>\n<li><strong>Have a complete eye examination from the age of 50<\/strong>, and earlier if there is a family history, even if you see well.<\/li><\/ul>\n<h2 class='wp-block-heading'><strong>Is it the same as cataracts? Other retinal diseases \ud83d\udd0d<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">No. <a href=\"https:\/\/ramirezgalvez.com\/en\/eye-problems\/cataracts\/\">Cataracts<\/a> are a clouding of the lens and are treated with surgery; AMD affects the retina and cataract surgery does not correct it. Both can occur in the same person, which is why a complete examination matters. If you have diabetes, you should also know about <a href=\"https:\/\/ramirezgalvez.com\/en\/eye-problems\/diabetic-retinopathy\/\">diabetic retinopathy<\/a>, and if you see flashes or a \u201ccurtain\u201d across your vision, read about <a href=\"https:\/\/ramirezgalvez.com\/en\/eye-problems\/retinal-detachment\/\">retinal detachment<\/a>. And remember to monitor eye pressure too: <a href=\"https:\/\/ramirezgalvez.com\/en\/eye-problems\/glaucoma\/\">glaucoma<\/a> is also silent.<\/p>\n<h2 class='wp-block-heading'><strong>Frequently asked questions about macular degeneration \u2753<\/strong><\/h2>\n<h3 class='wp-block-heading'><strong>Does AMD cause total blindness?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">No. It affects central vision, but peripheral vision is preserved, so you can keep moving around independently.<\/p>\n<h3 class='wp-block-heading'><strong>Is it hereditary?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">There is a family predisposition: if your parents or siblings have had it, your risk is higher. That is why it is worth starting check-ups earlier.<\/p>\n<h3 class='wp-block-heading'><strong>Can it be cured?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Today the macula cannot be restored to its original state, but its progression can be slowed, especially if it is detected early. In the wet form, early treatment makes the difference.<\/p>\n<h3 class='wp-block-heading'><strong>How often should I have my eyes checked?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">As a general guide, a complete examination from the age of 50 and the frequency your ophthalmologist recommends for your case. If you already have AMD, follow-up is closer.<\/p>\n<h3 class='wp-block-heading'><strong>Do vitamins prevent AMD?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">They are not a preventive measure for everyone.
