Yellow spot is the everyday name for the macula, the small central area of the retina responsible for reading, recognising faces and seeing detail. The commonest yellow spot disease is age-related macular degeneration (AMD), which has a slow dry form and a faster wet form. Others include diabetic macular oedema, macular hole, epiretinal membrane, central serous retinopathy and inherited dystrophies such as Stargardt disease.
Macular disease affects central vision and spares side vision, so it does not lead to total darkness. Wet AMD can be controlled with injections if treated promptly. For dry AMD, options are still limited, and honest advice matters more than promises.
Symptoms
- Straight lines such as door frames looking wavy or bent
- A blurred, grey or dark patch in the centre of vision
- Difficulty reading and recognising faces despite up-to-date glasses
- Needing brighter light and more contrast
- Objects looking smaller or a different size in one eye
- Colours appearing washed out
- Slow recovery of vision after bright light
Causes and risk factors
AMD results from ageing changes in the layers under the macula, with waste deposits called drusen and, in the wet form, leaking new blood vessels. The main risks are age over 55 to 60, smoking, family history and certain genes; diet, blood pressure and light exposure play smaller roles. About 10 to 15 percent of people with AMD develop the wet form. Other macular diseases have their own causes: diabetes, vein occlusion, high myopia, traction from the vitreous gel, stress and steroid use in central serous retinopathy, and single-gene faults in dystrophies.
How it is diagnosed
- Visual acuity and Amsler grid: Simple checks for central blur and distortion; the grid is also used for home monitoring.
- Dilated retinal examination: Shows drusen, pigment change, bleeding or a hole.
- OCT scan: The key test. A quick, non-contact cross-section of the macula showing fluid, membranes, holes and thinning.
- OCT angiography or fluorescein and ICG angiography: Identify and map abnormal vessels in wet AMD and related conditions.
- Fundus autofluorescence: Tracks areas of cell loss in dry AMD and dystrophies.
Treatment options
- Anti-VEGF injections for wet AMD: Injections into the eye every 4 to 16 weeks, often for years. They stabilise vision in most people and improve it in about a third. Delay of even weeks costs vision.
- AREDS2 supplements: A specific vitamin and mineral formula that modestly reduces progression from intermediate to advanced AMD. It does not help early disease or restore vision.
- Stopping smoking and a diet rich in leafy greens and fish: The most useful lifestyle steps.
- Complement inhibitor injections for geographic atrophy: Approved in some countries. They slow the growth of atrophy slightly but do not improve vision and may raise the risk of wet AMD; availability varies.
- Vitrectomy: For macular hole and epiretinal membrane, which are mechanical problems with a surgical solution.
- Low vision aids and rehabilitation: Magnifiers, lighting, electronic devices and training to make the most of remaining sight.
- Unproven therapies: Stem cell injections, microcurrent and similar offers for dry AMD lack good evidence, and clinics selling stem cells have caused blindness.
When it is urgent
Sudden distortion, a new dark patch in the centre of your vision, or a rapid drop in vision in one eye may mean wet AMD or another acute macular problem. You need assessment by a local eye service within days, ideally within a week, not after arranging travel. Sudden painless loss of vision in one eye needs same-day care.
Travelling to Türkiye for treatment
Wet AMD needs injections at regular intervals, often for years, with an OCT scan at each visit. That only works close to home, and travelling for each injection is neither practical nor safe for your sight. A visit can reasonably offer a detailed macular work-up, a second opinion on the diagnosis or on whether treatment is working, planned surgery for a macular hole or membrane (remembering the no-fly period if gas is used), and a low vision assessment. Be wary of any offer to cure dry AMD.

Frequently Asked Questions
Will I go blind?
Macular disease does not cause total blindness, because side vision is preserved. It can make reading and driving impossible in advanced cases.
Do the supplements really work?
The AREDS2 formula has trial evidence for people with intermediate AMD or advanced AMD in one eye. The benefit is real but modest.
How do I check my own eyes?
Look at an Amsler grid or a tiled wall with each eye separately, with reading glasses on, once a week. Report any new distortion promptly.
Is dry AMD treatable?
There is no treatment that restores vision. Supplements, not smoking, monitoring for conversion to wet AMD and low vision support are the mainstays.
