Symptoms
In dry AMD, the cells in the center of the retina that provide sharp detail slowly lose function. As these photoreceptor cells and their support layers weaken, the eye can no longer focus light clearly, causing vision to appear blurred.
When retinal cells in the macula are damaged unevenly, they stop lining up properly. This disrupts how visual signals are sent to the brain, making straight lines appear bent, wavy, or distorted.
As dry AMD progresses, groups of retinal cells may stop working or die in the center of the macula. This creates a dark, blurry, or empty spot in central vision, while side (peripheral) vision often remains intact.
Dry AMD damages rod cells, which are responsible for vision in low light. When these cells don’t function well, it becomes harder to see in dim conditions, adapt to darkness, or drive safely at night.
Depth perception depends on clear, balanced input from both eyes. Damage to central retinal cells reduces the accuracy of visual signals, making it harder to judge distances, steps, curbs, or moving objects.
Cone cells in the macula help the eye see bright, vivid colors. As these cells are damaged in dry AMD, colors may appear dull, washed out, or less intense than before.
When cone cells that detect different colors are affected unevenly, the brain receives weaker or mixed signals. This makes it harder to tell similar colors apart, such as blues and greens or dark shades.
As retinal cells and their protective layers break down, the eye loses its ability to adjust normally to bright light. This can make sunlight, headlights, or indoor lighting feel uncomfortable or overwhelming.
Signs of Dry AMD
Dry AMD develops due to a complex interplay of genetic, environmental, and aging factors. Here’s a closer look at the cellular mechanisms involved:
What Happens if AMD is Left Untreated?
If untreated, intermediate AMD can develop into advanced forms:
(GA), which causes permanent damage to the macula;
A rarer but fast-progressing form leading to severe vision loss due to abnormal blood vessels growing behind the retina
