What is the Cornea?

What is the Cornea?

The cornea is the clear area that lets light in through to the eyes. When you look at the color of someone’s eyes, you’re actually seeing the iris (the colored part of the eye) through the cornea.

The cornea is comprised of 5 layers, with each layer performing a specific function.  If there are problems with any of the layers, whether a new issue or one that has been present since birth, it can cause a person to experience a range of vision issues from blurry vision to blindness.

The type and severity of cornea problems depends on where and when the problem started as well as the cause of the problem. Where and when the problem started will determine what part of the cornea is affected and what type of symptoms the patient can experience. Medical conditions can also cause corneal issues like Vitamin A deficiency, High cholesterol, Lead poisoning, etc. Simply put, many different factors can affect the cornea, and ultimately your vision.

If you’re having any of these symptoms, such as dryness, irritation, redness, inflammation, swelling, or pain, call to make an appointment with a specialist in our office today to get the attention and care you need.


Common Conditions that Affect the Cornea

Corneal abrasion: A scratch to the cornea. Treatment for a scratched cornea may include eye drops and/or topical antibiotics. If left untreated a corneal abrasion can cause infection and a corneal ulcer, which can threaten your vision.

Contact Lens Over-wear: This occurs when the patient either wears their contact lenses for too long a period or wears them during sleep. This can lead to a Corneal Infection. Symptoms include redness, soreness, blurry vision, irritated eyes and/or vision loss.

Corneal Infection: An infection in your cornea which can result from many sources, including corneal abrasion and contact lens over-wear. A corneal infection can be vision threatening and needs urgent attention.  If you believe you may have a corneal infection, call our office today to make an appointment.

Blunt Orbital Contusion: A blunt trauma/injury to the eye or eye socket

Keratoconus: A condition where the cornea bulges out and becomes irregularly shaped, causing blurry vision, sensitivity to light, pain and even vision loss. Treatment varies according to the stage and severity of the disease.

Dry Eye Syndrome: A chronic condition that may be the result of many issues, including lifestyle choices, other medical conditions, medications and other health conditions.  Treatment for dry eye depends on the underlying cause of the dryness.  At Vision Specialists of California, we specialize in treating mild, moderate, and severe symptoms of dry eye disease.

Cornea Testing

There are many issues involving the cornea that can result in having to see a cornea specialist. Once at the doctor’s office, there are a number of diagnostic tests that need to be performed, in addition to the comprehensive ocular exam done in our clinics. These additional, more advanced diagnostic tests may include optic coherence tomography (OCT), ultrasound bio-microscopy, corneal pachymetry, corneal topography, and specular microscopy. This is not a complete list of all tests available, so be aware that the doctor may order additional testing, according to each patient’s needs.
