The macula (macula lutea) is a tiny area in the centre of the retina that determines our ability to see the world clearly and in detail. Thanks to the macula, we can read small print, drive a car, recognise faces, and distinguish the finest shades of colour.<\/p>\n
When problems arise with the macula \u2014 whether age\u2011related changes, swelling, or a micro\u2011tear (macular hole) \u2014 the quality of central vision deteriorates significantly. This article explains where the macula is located, how it is structured, what functions it performs, and which diseases can affect it.<\/p>\n
The macula is a specialised area of the retina, situated on the back wall of the eyeball (the fundus). It appears as a small yellowish area due to a high concentration of light\u2011sensitive pigment.<\/p>\n
The retina is the inner layer of the eye responsible for light perception. The macula occupies only a small part of it, but it provides the highest quality and sharpest vision. When an ophthalmologist examines the fundus, they evaluate the condition of the macula first.<\/p>\n
Without a healthy macula, everyday tasks become extremely difficult. This area of the retina gives us:<\/p>\n
If the macula is damaged, peripheral vision may remain good, but a person loses the ability to see what they are looking at directly.<\/p>\n
The macula is not just a “spot” \u2014 it is a complexly organised structure with several zones:<\/p>\n
Located in the very centre of the macula (diameter about 1.5 mm). This is the key area for sharpest vision. It has the highest density of cones \u2014 photoreceptors responsible for colour and detail.<\/p>\n
A depression inside the fovea (diameter about 0.35 mm). It appears as a small shiny reflex. The foveola provides the maximum possible visual acuity.<\/p>\n
An area inside the fovea with no blood vessels. This allows light to reach the photoreceptors without any interference. On angiograms, this zone looks darker than the surrounding tissue.<\/p>\n
The area surrounding the fovea (width about 0.5 mm). This is the thickest part of the retina.<\/p>\n
The outer edge of the macula (diameter about 3.5 mm). A transitional area from central to peripheral vision.<\/p>\n
The macula performs several critically important tasks that go far beyond simple “seeing”.<\/p>\n
Thanks to the high density of cones in the fovea, the macula allows us to distinguish the finest details: reading small fonts, seeing fabric textures, noticing tiny defects.<\/p>\n
Cones in the macula are specialised to detect different wavelengths of light (red, green, blue). Without a healthy macula, the world becomes dull and colours lose their saturation.<\/p>\n
The macula instantly transmits information about moving objects in the visual field to the brain. This is essential for driving, playing sports, and reacting to rapid changes in the environment.<\/p>\n
The macula is the fixation point for each eye. The brain combines signals from the right and left maculae into a single three\u2011dimensional image, allowing us to judge depth, distance, and volume.<\/p>\n
Diseases of the macula severely reduce quality of life because they affect central vision directly. The most common conditions are listed below.<\/p>\n
The most common macular disease, especially in people over 65. It involves progressive thinning or abnormal tissue growth in the centre of the retina. Peripheral vision usually remains, but reading, recognising faces, and watching television become impossible.<\/p>\n
Fluid accumulation within the macula. The most common cause is diabetes mellitus (diabetic macular oedema). It can also occur with retinal vein occlusion, uveitis, after eye surgery, or as a side effect of certain medications. Symptoms: blurred vision, distortion of straight lines.<\/p>\n
A microscopic tear in the centre of the macula. Most often caused by traction (pulling) of the vitreous gel, which is normally attached to the retina. The disease has 4 stages:<\/p>\n
A thin transparent membrane forms on the surface of the macula. Over time, it contracts and wrinkles the retina, causing image distortion (straight lines appear wavy). Early stages may be unnoticed, but as it progresses, reading becomes difficult and a dark spot may appear in central vision.<\/p>\n
Any of the conditions described above requires immediate consultation with an ophthalmologist specialising in retinal diseases. Self\u2011diagnosis and delayed treatment can lead to irreversible central vision loss.<\/p>\n
If you notice any of these symptoms \u2014 do not delay a visit to a specialist.<\/p>\n
Valenia Health Services\u00a0specialises in arranging medical care for international patients in the best clinics of Barcelona. We work with leading ophthalmology centres in the city that successfully treat all types of macular pathology \u2014 from age\u2011related degeneration to macular holes and epiretinal membranes.<\/p>\n
We do not perform treatment ourselves, but we guarantee that you will see the best specialists in Spain, receive an accurate diagnosis, and get modern treatment.<\/p>\n
The macula is a unique and extremely vulnerable structure of the eye. It makes our vision sharp, colourful, and detailed. Any macular disease, even at an early stage, requires specialist attention.<\/p>\n
Timely diagnosis and proper treatment, organised in leading ophthalmology centres in Barcelona, can preserve vision for many years.<\/p>\n
