A multifaceted, intricate process is necessary for normal eyesight. The cornea and lens of the eye allow light to enter, and the iris helps to focus the image. The retina, which is made up of millions of minuscule nerve endings, receives the light projection onto its rear wall and processes it. The retina then converts these images into nerve impulses, which the optic nerve then sends to the brain…..CONTINUE READING
People who are developing blindness frequently experience vision impairment first, which develops into blindness. Blindness doesn’t always result in utter darkness; it can impair one or both eyes. Even though they cannot see anything clearly, many persons who are regarded as blind can nevertheless make out some light or shadows.
Less than 4% of blindness instances worldwide are brought on by eye trauma or damage; the majority of blindness cases are brought on by eye problems. Eye injuries can result in a full recovery in about 77% of cases, while minor impairment affects another 11%.
According to Healthline & WebMD, here are 4 common eye problems that cause blindness in not treated early:
When the eye’s ordinarily crystal-clear lens gets hazy, cataracts develop. As a result, the colors fade, and it becomes difficult to see through glare. More than 22 million Americans have cataracts in one or both of their eyes, making cataracts the leading cause of blindness worldwide. By the time people are 80 years old, more than half of them could either have a cataract or have had cataract surgery.
Glaucoma often develops when the fluid pressure in one or both eyes starts to gradually rise. The optic nerve and retina are harmed by this pressure, which gradually reduces peripheral vision. According to experts, 2.3 million Americans have received a glaucoma diagnosis, and an additional 2 million have the disease but are unaware of their worsening vision.
Glaucoma cannot be cured, but it can be managed with prescription eye drops or surgery. Glaucoma causes vision loss that cannot be recovered. Regular eye exams are crucial for detecting glaucoma early, as treatment can preserve your eyesight.
3. Macular Degeneration
The macula, or the retinal nerve endings that are essential for clear center vision, gradually deteriorates as a result of macular degeneration. This disorder causes blurring and blind patches in the central vision of those who have it.
Although macular degeneration cannot be cured, it can be slowed down with some medications. These include eye injections with specific drugs, laser surgery, photodynamic therapy, and combination vitamin therapy.
4. Diabetic Retinopathy
When diabetes-related systemic damage starts to have an impact on the retina, it is known as diabetic retinopathy. In particular, diabetes can have a deleterious impact on the blood vessels that supply the retina, leading to retinal hemorrhage and visual loss…..CONTINUE READING
