Which symptom is NOT commonly associated with macular degeneration?

Macular degeneration, particularly age-related macular degeneration (AMD), primarily affects central vision and is characterized by symptoms such as blurriness, difficulty seeing in low light, and trouble with objects in the center of vision. These are all directly related to the deterioration of the macula, the part of the retina responsible for sharp, central vision.

Extreme redness in the eyes is not a typical symptom associated with macular degeneration. Instead, such redness is more often linked to other conditions, such as eye infections or inflammatory processes, rather than to the degeneration of the macula itself. This makes extreme redness in the eyes an unlikely symptom in the context of macular degeneration, confirming it as the correct answer.
