What condition is characterized by deposits causing impaired vision, possibly leading to blindness?

Macular degeneration is a condition that primarily affects the macula, the part of the retina responsible for central vision. This degeneration can occur due to the formation of deposits called drusen, which can impair vision gradually or suddenly, leading to a significant loss of central vision. This loss can be particularly concerning as it may hinder activities such as reading or recognizing faces, and in advanced stages, it can lead to blindness.

This condition is often associated with aging, and while there are different types of macular degeneration, the age-related form is the most common. Early detection and lifestyle changes can help manage the progression, but permanent vision damage can occur if the condition worsens.

In contrast, other conditions listed have different mechanisms and effects on vision. Glaucoma typically leads to peripheral vision loss due to increased pressure in the eye. Cataracts result in clouding of the lens, affecting clarity of vision. Diabetic retinopathy arises from diabetes-related changes in the retina, primarily affecting blood vessels. Each of these conditions has distinct characteristics and does not primarily result from the same type of deposits seen in macular degeneration.
