Signs You May Have a Cornea Disorder

The cornea is an essential part of the eye. It protects the iris and helps focus light onto the retina so we can see. Because healthy corneas are required for healthy vision, it is important to understand the many conditions that may affect them. Even a slight change in the cornea could lead to disastrous results.

At Focal Point Vision, our board-certified ophthalmologists and skilled optometrists can help you identify and treat certain cornea disorders. If you notice any abnormalities that could indicate corneal disease in San Antonio, TX, we encourage you to contact our clinic for a consultation right away. Our medical professionals prioritize high-quality eye care you can count on.

Corneal ulcer

A corneal ulcer is an open sore that develops on the cornea. It usually results from an infection or injury to the eye. If left untreated, the ulcer could penetrate the cornea, leading to permanent loss of vision. Your eye doctor can identify corneal ulcers using magnifying instruments during a simple exam at our office. We may also check for foreign materials or other signs of issues. When addressed early on, corneal ulcers are completely curable. Focal Point Vision may suggest antibiotic eye drops or other treatments to decrease side effects, such as inflammation or scarring.


A pterygium is a growth of tissue on the conjunctiva, which is the clear membrane covering the outer surface of your eye. The tissue can remain small or grow large enough to cover the cornea. Larger pterygia can also change the shape of the cornea and cause blurred vision. Pterygiums are usually noncancerous and are often found on the inner side of the cornea. Common causes of pterygiums include exposure to ultraviolet radiation as well as excess wind, dust, sand, or smoke. At Focal Point Vision, our physicians recommend wearing 100% UV protective lenses to lessen your risk of developing pterygiums.


Keratoconus is a disorder that causes structural issues in the cornea. Patients with keratoconus, sometimes, have cone-shaped corneas that lead to vision problems. Sensitivity to light or blurred vision are some of the more common signs of this condition. It is important to meet with a trained eye surgeon with years of experience since keratoconus could cause blindness when left untreated. Our board-certified ophthalmologists in San Antonio, TX specialize in treating keratoconus and offer solutions to restore your sight. If you have noticed any potential signs of keratoconus, call to schedule an appointment right away.

Corneal dystrophy

Corneal dystrophy is an inherited disease of the cornea that may worsen over time. This condition causes the normally clear cornea to become cloudy or irregular. There are several different types of dystrophies categorized according to the layer of the cornea they affect. If your case is mild, it may not cause any symptoms at all. People with mild to moderate cases can sometimes correct vision issues with glasses or contact lenses. Severe dystrophy may, however, require surgical intervention. Fortunately, most forms of corneal dystrophy can be diagnosed during a routine eye examination.


Keratitis occurs when the cornea becomes inflamed. Sometimes, this is the result of a bacterial infection or wearing your contact lenses for long periods of time. Just like other cornea disorders, keratitis may lead to vision loss or blindness if it is not addressed right away. The first signs of keratitis are usually redness or eye pain, but other patients experience burning or light sensitivity. These signs will vary in intensity based on what caused it to happen in the first place. To prevent keratitis from forming, Focal Point Vision recommends disinfecting your contact lenses frequently and washing your hands before touching your face.

Corneal abrasion

The cornea is a very sensitive part of the body, so even the smallest injury could cause a scratch. This is called a corneal abrasion, and it is one of the most common eye injuries we see at our clinic in San Antonio, TX. A corneal abrasion essentially creates an open wound that increases your risk of an eye infection. Most corneal abrasions are caused by small objects, such as a fingernail. However, a scratched cornea can cause significant discomfort or pain, red eyes, and light sensitivity. Patients with a corneal abrasion should flush their eyes with room-temperature water and seek immediate medical attention.
