Macular degeneration is a significant eye condition that affects millions worldwide and can lead to vision loss.

Types of Macular Degeneration

• Dry Macular Degeneration
• Wet Macular Degeneration

Dry Macular Degeneration

Dry macular degeneration is the most common form, accounting for about 85-90% of all cases. It develops slowly and is characterized by the thinning of the macula, leading to gradual vision loss.

Causes

Risk factors include age, genetics, smoking, and poor diet.

Symptoms

• Blurry or distorted vision
• Difficulty reading or seeing in low light
• Blind spots in the central vision

Wet Macular Degeneration

Wet macular degeneration is less common but more severe. It occurs when abnormal blood vessels grow under the retina, leaking fluid and blood, which can lead to rapid vision loss.

Causes

This form is usually associated with advanced dry macular degeneration.

Symptoms

• Sudden changes in vision
• Dark or empty areas in the center of vision
• Distortion of straight lines
