Overview
Macular degeneration is a common cause of vision loss in older adults. It does not cause total blindness, as side vision is usually kept, but it can make reading, driving and recognising faces difficult.
Symptoms
- Blurred or distorted central vision
- Straight lines appearing wavy
- A dark or empty area in the centre of vision
- Difficulty reading or seeing fine detail
- Colours appearing less bright
Causes and risk factors
Risk factors include age over 50, smoking, family history, high blood pressure and an unhealthy diet.
Diagnosis
An eye specialist examines the retina and may use OCT scans and fluorescein angiography.
Treatment
Dry macular degeneration has no cure, but vitamins and stopping smoking may slow it. Wet macular degeneration is treated with injections into the eye. Low-vision aids help daily life.
When to see a doctor
Seek prompt eye care for sudden distortion or loss of central vision. Regular eye checks are important after 50. KIH can guide you to an eye specialist.
