The cornea is the eye's transparent, dome-shaped front window. It supplies almost two thirds of the eye's focusing ability. It provides us with a clean view and is essential for clear vision. Additionally, it aids in protecting the remainder of the eye from contaminants like dust and pollution.
A feeling of something being in the eye, sensitivity to light, and a foreign body sensation are common symptoms of infections or inflammation in conjunction with corneal abrasions. Both bacteria in and around the eye and the herpes virus, which is present in the majority of people and can spread to the nerve endings of the eye and create an active corneal infection, can result in corneal ulcers and infiltrates.
Even when worn properly, contact lenses can prevent the cornea from receiving enough oxygen, which is necessary for the cornea's healthy operation and clarity. The cornea may eventually "protest" and manifest symptoms like redness, irritation, and visual blurriness if your contact lens hygiene is subpar or you don't replace lenses as regularly as is essential.
The common condition known as dry eye syndrome can seriously harm the cornea. To preserve the cornea and keep it wet at night, some people don't generate enough tears, and others' eyes don't close completely.
Others suffer from blepharitis, a common ailment that causes persistent lid infections and results in an unstable tear film, which can exacerbate dry eye and cause inflammation of the corneal surface.
In keratoconus, the cornea protrudes or steepens and vision gets more hazy. Due to uneven shape of cornea, the contact lenses may not stay in place. A person with bullous keratopathy or Fuchs' endothelial dystrophy may initially become aware of light glare at night or in strong sunshine.
Vision may be cloudy or fuzzy in the morning as these conditions worsen and become clearer over the day. Later in the day, eyesight will continue to become more blurry as the condition worsens, and finally it may not clear at all. On occasion, a fleshy growth can form on the cornea after growing on the white area of the eye, causing irritation, blurry vision, and an unsightly cosmetic look. Pterygium is the name of the growth, and it can be surgically removed.
Corneal illness needs to be treated very away, just like any severe eye infection. To treat the numerous disorders that can affect the cornea, antibiotics and steroids can be applied topically and infrequently taken orally.
The unhealthy cornea is surgically removed (completely or partially) during a corneal transplant procedure, and it is then replaced with a donor cornea that is healthy and transparent (complete or partial). The term "keratoplasty" also refers to a cornea transplant procedure.
Our professionals begin the treatment after determining the bacterium that caused the eye infection in accordance with the drug sensitivity assessment.
There is a full range of therapy options, including corneal transplantation, intrastromal ring segments, implantable contact lenses (ICL), and collagen crosslinking with riboflavin.
1. What is a corneal abrasion?
A scratch on the cornea's surface is referred to as a corneal abrasion. When applying makeup, playing, etc., you could unintentionally stab your eyes with a fingernail or another sharp object.
2. How is a child prone to corneal abrasion?
Another factor contributing to ocular abrasions is airborne chemical pollution and odours. The cornea of older children can also become damaged by wearing lenses that don't fit properly and applying makeup incorrectly. Treatment with corneal abrasion is necessary if the cornea is injured.
