MaculardegenerationDry maculardegeneration is a chronic eye disease that causes vision loss in the center of your field of vision. Dry maculardegeneration is marked by deterioration of the macula (MAK-u-luh), which is in the center of the retina - the layer of tissue on the inside back wall of your eyeball.

Dry maculardegeneration is one of two types of age-related maculardegeneration. The other type - wet maculardegeneration - is characterized by swelling caused by leaky blood vessels in the back of the eye. Dry macular degeneration isn't associated with swelling and is the more-common form of the disease.

Dry macular degeneration doesn't cause total blindness, but it worsens your quality of life by blurring or causing a blind spot in your central vision. Clear central vision is necessary for reading, driving and recognizing faces.

Symptoms

Dry macular degeneration symptoms usually develop gradually. You may notice these vision changes:

  • The need for increasingly bright light when reading or doing close work
  • Increasing difficulty adapting to low light levels, such as when entering a dimly lit restaurant
  • Increasing blurriness of printed words
  • A decrease in the intensity or brightness of colors
  • Difficulty recognizing faces
  • A gradual increase in the haziness of your overall vision
  • A blurred or blind spot in the center of your field of vision
  • Hallucinations of geometric shapes or people, in cases of advanced macular degeneration

Dry maculardegeneration may affect one eye or both eyes. If only one eye is affected, you may not notice any or much change in your vision because your good eye compensates for the weak one.

When to see a doctor

See your eye doctor if:

  • You notice changes in your central vision
  • Your ability to see colors and fine detail becomes impaired

These changes may be the first indication of maculardegeneration, particularly if you are older than 50.

Does Macular Degeneration cause mydriasis?

Macular degeneration itself does not directly cause mydriasis (dilated pupils). Mydriasis can result from various factors, including medications, neurological conditions, or eye trauma, but it is not a typical symptom of macular degeneration. Macular degeneration primarily affects central vision and the retina, leading to vision loss rather than changes in pupil size. If someone experiences mydriasis, it's important to consult a healthcare professional to determine the underlying cause.

What is age-related macular degeneration (AMD)?

Macular Degeneration or Age Related Macular Degeneration (AMD) is a condition that blurs central vision. This happens when the macula, which is the portion of the eye responsible for clear & sharp vision gets damaged due to aging or other factors. AMD is a common & leading cause of vision impairment in older adults. Although it may not cause blindness, it can affect your ability to read, see faces, drive, and do work like cooking or fixing things around your house. The speed of degeneration varies & can occur very slowly in some people, and much faster in others. Early AMD may not cause vision loss. It is important to have regular eye examinations to determine if you have AMD. Sanjeevan Netralaya has treated thousands of patients with Macular Degeneration effectively with Advanced Ayurvedic Treatment that causes absolutely no side effects.
