In fact, since the improvement in water supply facilitates facial cleanliness, it is one of the four components of the SAFE strategy for trachoma control. Trachoma is transmitted due to poor facial and hand hygiene. Provision of Clean Water: Trachoma is caused by Chlamydia trachomatis, which causes corneal blindness due to lid distortions are known as entropion and trichiasis and due to an increased probability of infections and ulcerations.The approach to managing corneal blindness is three-pronged: prevention, treatment, and rehabilitation. What are the measures for prevention of corneal blindness? Traditional practices of using honey as an eye drop and ginger juice for eye cleansing are potentially disastrous, as is the indiscriminate use and dispensing of steroid eye drops by chemists and quacks. Lifestyle Issues: An essential consideration in this regard, especially in a developing country like India, with a rich system of traditional medicine or home remedies, is the fact that several ayurvedic drops, kajal, and surma have been traditionally used which may cause more harm than good, resulting in loss of vision.Other Corneal Disorders: Certain hereditary and acquired disorders like Fuch’s Endothelial Dystrophy, Pseudophakic bullous Keratopathy, and other corneal degenerations and dystrophies can also cause a profound loss of vision.Congenital Diseases: Also, each year 3.5 Lakh children are affected by blindness, either due to a congenital disorder (born blind) or due to corneal infections and ulcerations in early infancy.Trauma: Eye trauma and corneal ulcerations are the second most important disease burden, resulting in 2.0 million new cases of blindness each year.Malnutrition: Vitamin A deficiency is also an important reason for childhood blindness, affecting children with malnutrition and failure to thrive.Relatively rare infections like onchocerciasis and leprosy have resulted in 2.5 Lakh cases of blindness. Trachoma, an eye infection, is the leading cause of corneal scarring and has blinded as many as9 million people worldwide. Infections and Ulcerations: Bacterial, fungal, or viral keratitis or infection of the cornea due to various microbes are the most important causes.What are the causes of corneal blindness? The other leading causes include cataract, glaucoma, and age-related macular degeneration. It is the 4th most common cause of blindness all over the world, accounting for over 5% of the total blind population. What is corneal blindness?Īny profound decrease in vision or blindness due to diseases of the cornea is termed corneal blindness. In scarring, which can be due to infections, inflammations, trauma, or hereditary diseases of the cornea, can result in severe loss of vision and even corneal blindness.

The cornea, along with the natural lens of the eye is responsible for focusing the rays of light entering the eye, on to the retina, the light-sensitive portion of the eye.įor the cornea to function correctly, it must remain transparent and free from any surface irregularities. The black part of the eye, the iris, if you observe, is covered by the transparent, dome-shaped cornea. The cornea is the outermost layer of the eye, which is clear and dome-shaped. It makes corneal blindness a unique challenge for the eye care provider. By and large, in low and middle-income groups, infections and trauma remain the most important causes, followed by poor access to proper eye care.Īlso, management of corneal blindness requires a corneal transplant, a surgery that is complex and dependent on cadaveric corneal donations and needs tremendous post-operative care and follow-up. Unlike cataract, glaucoma and Age-Related Macular Degeneration, corneal blindness affects youth, mainly from rural areas, and especially those from a lower socio-economic background, who anyway have inadequate access to healthcare. Corneal blindness has a considerable health and economic burden on the community and the state exchequer especially since it affects the relatively younger population which is generally economically productive.
