Age-related Macular Degeneration (AMD)
AMD is a chronic irreversible condition that results in vision loss in the centre of the visual field ( macula) because of damage to the Retina. The condition affects the patient as itthey may have difficulty reading, recognize faces etc. Their peripheral vision remain intact for most people allowing them to remain independent for most of the daily activities.AMD is one of the leading causes of blindness affecting people over 50 years.
A cataract is a clouding of the lens of the eye that affects vision varying in degree from slight to complete opacity and obstructing the passage of light. Early in the development of age-related cataract, the power of the lens may be decreased, causing nearsightedness (myopia), and the gradual yellowing and opacification of thelens may reduce the perception of blue colors.
Most cataracts are related to ageing and are common in older people. A cataract can occur in either or both eyes but do not spread from one eye to the other. It may, however,impair your ability to see well enough to perform daily tasks and can become worse over time.
