Conclusion: Prevalence of vision impairment was found to be substantial among the senior group studied. Low eyesight was mostly caused by refractive error, cataracts, and retinal diseases, among other things.
Age-related macular degeneration (AMD) is the most common cause of visual loss in persons over the age of 65, and it is preventable.
A number of age-related eye illnesses, such as age-related macular degeneration, cataracts, diabetic retinopathy, and glaucoma, are the primary causes of blindness and impaired vision in the United States.
When it comes to vision loss in senior persons, age-related macular degeneration (AMD), cataract, glaucoma, and diabetic retinopathy are the most prevalent causes. AMD is the most common cause of recognized blindness in adults over the age of 50 in the western world, accounting for more than half of all cases.
Presbyopia, glaucoma, dry eyes, age-related macular degeneration, cataracts, and temporal arteritis are all common age-related eye issues.
Because of the narrowing of the macula, it results in impaired or diminished central vision (MAK-u-luh). The macula is the portion of the retina that is responsible for sharp vision when you are looking directly at something. A dry macular degeneration that begins in one or both eyes might progress to impair both eyes.
A number of conditions, such as age-related macular degeneration, diabetes, and glaucoma, are known to induce poor vision. It is also possible to have low vision due to diseases such as cancer of the eye, albinism, brain damage, or hereditary eye problems such as retinitis pigmentosa.
In the United States, a person with low vision is defined as one who has impairment of visual functioning even after treatment and/or standard refractive correction, and who has a visual acuity of less than 6/18 to light perception or a visual field of less than 10 degrees from the point of fixation but who uses, or may use, vision.
At the age of 45, fewer than one percent of the population is likely to have poor vision, but by the age of 75, that number has increased to about five percent, and by the age of 85, it has increased to fifteen percent. Having said that, you might have an age-related eye condition for years, if not decades, without experiencing any symptoms that would be life-altering.
Cataracts, refractive error, corneal blindness, and early diabetic macular oedema are all treatable conditions that may be reversed in most cases. Optic atrophy, glaucoma, retinal degeneration, and age-related macular degeneration are all conditions that typically result in irreversible vision loss. The majority of these disorders are described in detail later in this article.
It is totally typical for people to have changes in their light sensitivity as they get older. When individuals reach the age of 60, their resting pupil size diminishes, resulting in their receiving just one-third the amount of light that they would otherwise receive. This implies that they will have a harder time seeing in low light and that their eyes will grow more susceptible to glare.
