Age-related eye diseases

Eye health can bring more than one headache to seniors. Cataracts, age-related macular degeneration, dry eyes, glaucoma and diabetic retinopathy are five of the most common eye ailments among the elderly. It is therefore useful to know what these diseases are and how they are treated.

Cataract surgery is the most frequent operation performed on people worldwide and has reached a very high degree of perfection with very few complications. If multifocal intraocular lenses are implanted during the operation, it is possible to dispense with glasses after the operation. If we want to avoid problems, it is better not to wait until they are very advanced to perform the surgery. There are no known preventive measures against cataracts.

More and more older and younger people are showing symptoms of dry eyes, mainly at older ages. Postmenopausal women are the most affected (due to hormonal changes), but everyone can have this problem temporarily or chronically. Many medications favor dry eyes and dry mouth, such as antidepressants, anxiolytics, sleeping pills, beta-blockers, etc.

A disease characterized by the aging of the crystalline lens.

Refraction occurs when light changes direction as it passes through one object to another. Vision occurs when light rays are deflected (refracted) as they pass through the cornea and lens. This light is then focused onto the retina. The retina transforms the light into electrical impulses that are sent to the brain through the optic nerve. The brain interprets these messages, converting them into the images we see.

Myopia is a condition in which near objects are seen clearly, while distant objects are blurred. With nearsightedness, light is focused in front of the retina instead of on the retina.  Learn more about nearsightedness.

Astigmatism is a condition in which the eye does not focus light evenly on the retina, the light-sensitive tissue at the back of the eye. This can cause images to appear blurred or elongated.  Learn more about astigmatism.

Presbyopia is an age-related condition in which the ability to focus up close becomes more difficult. As the eye ages, the lens can no longer change shape enough to allow the eye to focus on close objects clearly.  Learn more about presbyopia.

Types of eye problems

Your best defense is to get regular checkups, because eye diseases do not always have symptoms. Early detection and early treatment can prevent blindness. If you have sudden vision changes, have blurred vision or see flashes of light, seek immediate help from an eye specialist. Other symptoms that require prompt attention are pain, double vision, fluid discharge from the eye, and swelling.
