Age Related Macular Degeneration in India
What is Macular Degeneration?
Macular degeneration encompasses various pathological yet prevalent conditions that impact the macula, leading to a decline in central vision. This degeneration occurs as a specific region of the retina undergoes deterioration. The macula plays a crucial role in tasks such as reading small prints, interpreting street signs, and even threading a needle.
Age-related macular degeneration, as the name suggests, is linked to the natural aging process, making it prevalent among older individuals. Among various macular issues, age-related macular degeneration is the most commonly observed. Symptoms of macular degeneration include distorted or dark areas in central vision, permanent central vision loss, and blurriness. It's worth noting that peripheral vision remains unaffected by macular degeneration.
What is Age-Related Macular Degeneration (AMD)?
This eye disease impacts the macula, a crucial part of the retina responsible for sending light signals to the brain for clear vision. Age-related macular degeneration (AMD) manifests in two forms: wet and dry. The progression of AMD is often gradual, making it challenging to detect changes in vision. However, there are instances where AMD advances rapidly, leading to vision loss in both eyes. AMD stands as the primary cause of vision impairment in older individuals, affecting central vision necessary for activities like sewing, driving, and reading.

Causes of Age-Related Macular Degeneration
Diagnosis of Age-Related Macular Degeneration
Signs and symptoms of the initial phase of macular degeneration can be observed. An optometrist will assess the eyes through a thorough eye examination and additional tests to ascertain the status of macular degeneration.
Dry Age-Related Macular Degeneration
Dry AMD, the most prevalent form of age-related macular degeneration, is considered the least severe. Insufficient nutrients causing damage to macula cells can lead to the accumulation of waste products called drusens, ultimately giving rise to dry AMD. The decline in vision occurs gradually over several years. In rare instances, individuals with dry AMD may progress to developing wet AMD. The three stages of dry AMD are :
Wet Age-Related Macular Degeneration
Wet AMD arises from the growth of abnormal blood vessels beneath the macula, causing damage to its cells. This form is considered the most severe, in contrast to dry AMD.
Treatment for Age-Related Macular Degeneration
Dry AMD currently lacks a cure, but the use of a magnifying lens can aid in easier reading. In contrast, there are treatment options available for wet AMD, including :
Advanced Age-Related Macular Degeneration
Both advanced dry and wet forms collectively referred to as advanced AMD can manifest in one eye with one or more forms, or in the same eye. This condition leads to significant vision loss.
Benefits of Early Detection of Age-Related Macular Degeneration
Detecting AMD in its early stages enhances the likelihood of preventing vision loss. The effectiveness of treatments tends to be higher when AMD is diagnosed early.
Cost of Age-Related Macular Degeneration
The cost of AMD treatment in India is considerably more affordable compared to other developed countries worldwide. The treatment for AMD varies depending on the stage of the disease.
