As we age, the light-sensing cells in the macula and their support cells become less efficient at repairing themselves. Over time, this natural wear and tear can lead to cell damage and vision changes.
In dry AMD, tiny yellow deposits called drusen form under the retina. These deposits interfere with the normal flow of oxygen and nutrients, gradually stressing and damaging retinal cells.
As damage continues, the retinal tissue, especially in the macula, can slowly thin and weaken. This reduces the retina’s ability to process light efficiently and transmit clear visual signals to the brain, leading to gradual loss of central vision and reduced detail perception.
Changes in the layer beneath the retina can limit how well nutrients and oxygen reach the macula. Without proper support, retinal cells may stop working or die.
The retina is exposed to light every day, which can create harmful molecules called free radicals. Over time, these can damage retinal cells, especially if the eye’s natural protective systems weaken.
Some people are genetically more likely to develop dry AMD. Having a close family member with AMD increases the risk.
Certain factors can increase the risk or speed up progression, including:
Smoking
Poor diet low in antioxidants
High blood pressure or cardiovascular disease
Long-term sun and UV exposure
What Causes Dry Age-Related Macular Degeneration (Dry AMD)?
Dry AMD develops when the cells in the macula, the part of the retina responsible for sharp central vision, slowly become damaged over time. Several factors usually work together rather than one single cause.
