Macular Degeneration

Also known as: Age-Related Macular Degeneration (AMD)

AMD is a progressive eye disease that destroys the macula — the central part of the retina responsible for sharp, detailed vision. It is the leading cause of vision loss in people over 50.

Understanding Macular Degeneration

AMD affects approximately 196 million people worldwide and is the leading cause of vision loss in developed countries. Prevalence increases dramatically with age.

Dry AMD (85-90% of cases) involves gradual thinning and atrophy of the macula. Wet AMD (10-15%) involves abnormal blood vessel growth under the retina that leaks fluid and blood, causing rapid vision loss.

Anti-VEGF injections have revolutionised wet AMD treatment, preserving and often improving vision. For dry AMD, the AREDS2 supplement formula can slow progression.

Common Symptoms

People with Macular Degeneration often experience the following symptoms.

Central Vision Blur

Gradual loss of sharp central vision while peripheral vision remains intact.

Metamorphopsia

Straight lines appearing wavy or distorted — an important early sign of wet AMD.

Scotoma

Dark or blank spots in the centre of vision.

Difficulty with Detailed Tasks

Reading, recognising faces, and driving become increasingly difficult.

Risk Factors

Certain factors may increase your likelihood of developing Macular Degeneration.

Age over 50

Smoking (strongest modifiable risk)

Family history

Caucasian descent

Treatment Options

Common approaches to managing macular degeneration. Always consult a healthcare provider for personalized treatment.

Anti-VEGF Injections

Ranibizumab, aflibercept, and faricimab injected into the eye for wet AMD. Often monthly initially.

AREDS2 Supplements

Specific vitamin combination (C, E, zinc, lutein, zeaxanthin) that reduces dry AMD progression by 25%.

Photodynamic Therapy

Light-activated drug injected intravenously destroys abnormal blood vessels in select wet AMD cases.

Low Vision Aids

Magnifiers, special glasses, and assistive technology to maximise remaining vision.

How It's Diagnosed

Dilated eye exam, OCT imaging for retinal layers, fluorescein angiography for wet AMD, and Amsler grid for monitoring at home.

When to See a Doctor

See an eye doctor urgently if you notice sudden distortion of straight lines, new dark spots in your vision, or rapid worsening of central vision — this may indicate wet AMD requiring urgent treatment.

Prevention Strategies

Steps that may help reduce the risk of developing or worsening macular degeneration.

Stop smoking

AREDS2 supplements for intermediate dry AMD

Regular eye exams after 50

Healthy diet rich in leafy greens and fish

Potential Complications

If left untreated or poorly managed, macular degeneration may lead to:

  • Severe central vision loss
  • Legal blindness
  • Depression
  • Loss of independence and driving ability

Frequently Asked Questions

Can macular degeneration cause complete blindness?

AMD does not cause total blindness. Peripheral vision is preserved, but central vision loss can be severe.

Can macular degeneration be reversed?

Currently no. Anti-VEGF treatment for wet AMD can improve vision, but lost cells from dry AMD cannot be restored.

Is macular degeneration hereditary?

Yes, there is a significant genetic component. Having a first-degree relative with AMD increases your risk.
