Statistical Overview and Some Hard-Hitting Facts About Eye Diseases
Statistics of Eye Diseases
- Blindness is estimated to be 1.1% in India, with 62.6 million people who have a visual impairment, according to the National Program for Control of Blindness and Visual Impairment (NPCB&VI).
- A cataract is the most common cause of blindness in India, accounting for 66.2% of all cases. Refractive errors, corneal opacities, glaucoma, and posterior segment disorders are significant causes.
- Diabetes retinopathy, a complication of diabetes that affects the eyes, is estimated to affect around 18.3% of diabetics in India.
- Trachoma, a bacterial-caused infectious eye disease, is still prevalent in some parts of India, particularly in rural areas. In India, the prevalence of active trachoma is estimated to be 3.6%.
- With an estimated 0.8 million blind children under 16, childhood blindness is a significant issue in India. Corneal scarring, congenital cataract, retinopathy of prematurity, and vitamin A deficiency are the leading causes of childhood blindness.
Some basic facts about Eye disease:
Here are some eye disease facts:
- Cataracts are a common age-related eye disease that causes clouding of the eye’s natural lens, resulting in reduced vision. Cataracts can be removed surgically.
- Glaucoma is a group of eye diseases that cause optic nerve damage, resulting in vision loss and blindness if untreated. It is known as the “silent thief of sight” because it can cause irreversible damage with no symptoms until the disease progresses.
- Diabetic retinopathy is a diabetes complication that affects the blood vessels in the retina, resulting in vision loss. People with diabetes should have regular eye exams to check for diabetic retinopathy.
- Dry eye syndrome is a common condition in which the eyes produce insufficient tears or evaporate too quickly, causing dryness, burning, and itching. Various factors, including aging, certain medications, and medical conditions, can contribute to it.
- Conjunctivitis is an inflammation of the conjunctiva, also known as pink eye (the clear membrane covering the eye’s white part and the inner surface of the eyelids). Viruses, bacteria, allergies, or irritants can all cause it.
- Retinal detachment is a medical emergency that occurs when the retina (the light-sensitive layer at the back of the eye) separates from the underlying tissue, resulting in vision loss. Trauma, diabetes, nearsightedness, and other factors can contribute to it.
- Optic neuritis is an optic nerve inflammation that can result in pain and loss of vision. It is frequently linked to multiple sclerosis, but other conditions can also cause it.
- Color blindness is a genetic condition in which people struggle to distinguish between colors. It affects approximately 8% of Northern European men and 0.5% of women.
