Normally a cornea will create a windshield to the eyes and has a dome-shaped like a ball. Sometimes that ball will not be able to hold its round shape and it will start to bulge outwards like a cone and this is called keratoconus. Your eyes will contain a protein called collagen and that will help the cornea to stay in its proper position. This is a special kind of fiber and when this fiber gets weak this will start to lose holding its shape. Your cornea will start to get its cone-like structure and this is why keratoconus occurs. People who do not have proper antioxidants in the cornea do not have that much protective shield before their cornea. These cells have many possibilities to produce harmful byproducts. Generally, the antioxidants will get out from them and protect the fiber but if the levels are low the cornea will start to bulge and the collisions will get weak. Get keratoconus treatment from one of India's top eye care service providers.
How it is caused?
There is no proper explanation of why keratoconus is formed. Some researchers have ideas about the keratoconus right from birth. One in 2000 people will get keratoconus, it may get initiated with puberty and the progression occurs in mid of the 30s.
During the early stage of keratoconus, you will be able to correct the vision problem with the help of a soft contact lens or with glasses. Later you will have to start making use of gas permeable contact lenses or other types of lenses like scleral lenses. If the condition turns out to be more progressive then you will have a moto cornea transplant.
Family history - If someone in the family has the same condition then there are greater chances for the next generation to get the issue. Right from the age of 10, you will have to start checking your child for vision.
Age factor - This kind of issue starts right from the teenager but in some cases, it will start right from early childhood or not till you're 30. It is less common in people aged more than 40.
Disorder- Studies have found that some connection between the systemic condition and keratoconus relates to osteogenesis imperfecta on down syndrome and retinitis pigmentosa.
Inflammation - The inflammation in the cornea can also be got mainly due to asthma or an allergy which has the high possibility of a breakdown of the tissue.
