Different Types of Conditions That the Cornea Is at Risk of
The cornea helps to focus light that comes into your eye onto the retina. Its nerves alert you to irritations that might harm your vision and eye health. It does not have blood vessels to give it nourishment. Rather, it gets the majority of its nourishment from the tears on the surface and the aqueous humor from inside your eye. The cornea has five layers. If an injury breaks through to a deeper layer, healing can take longer and may lead to blurred vision, sensitivity to light, pain, and tearing. A more serious injury will lead to corneal scarring. Because of the important role the cornea plays in your eyesight, it makes sense to know the different types of conditions that may affect it and the right Huntingdon Valley cornea treatment to get.
Allergies impact anyone. Often, eye allergies can be triggered by indoor allergens such as dander, mold, and dust, irritants such as perfume and smoke, as well as outdoor allergens such as pollen. These allergies can lead to itching, redness, watery discharge, and burning. It is important to eliminate the irritant to stop the allergy symptom.
Infections can impact both eyes and any of their parts. The lack of blood vessels can make it hard for the cornea to fight infections. The cornea can suffer infections such as conjunctivitis and corneal ulcers. Sometimes, viruses may also strike it causing infections such as herpes simplex and herpes zoster, which can affect vision and comfort. Treatment for corneal infections depends on the kind of infection. However, typically treatment includes eye creams, eye drops, and antibiotics.
Dry eyes can be persistent and quite painful for some people. Your tears wash away dirt and irritants as well as keep the surface of the eye moist and clean. In turn, this prevents possible irritation, infections, or damage. If your eye stops producing enough tears or quality tears, it can be hard for you to take part in daily activities. Dry eyes can develop because of allergies, skin disease, contact lenses, certain medications, and chemical or tobacco smoke exposure. Also, people who are more than 65 years old are at risk of dry eye.
