We treat many eye diseases, but some of the most common eye diseases diagnosed and often treated at Blanco EyeWorks in San Antonio are:

Conjunctivitis, Diabetic Eye Disease, Glaucoma, and Macular Degeneration.


“Eye diseases” is a broad term that refers to a host of diseases relating to the function of the eye. Below are descriptions of some of the more common types of eye diseases and their treatments. For more in-depth information, please contact us at Blanco EyeWorks for an appointment.

Conjunctivitis (Pink Eye)

Conjunctivitis is also called pink eye and is an infection and inflammation of the conjunctiva of your eye. The conjunctiva is the thin, protective membrane that covers the surface of the eyeball and inner surface of the eyelids. Conjunctivitis is highly contagious and is very common in children. Caused by bacteria, viruses, allergens, and irritants, conjunctivitis causes redness in the white of the eye and increased tearing and discharge.

Many minor cases of conjunctivitis can improve within two weeks, and some can develop into severe corneal inflammation and threaten your vision. If you suspect you or child has conjunctivitis, visit your Blanco EyeWorks for an examination and treatment.

Diabetic Eye Disease

If you have diabetes, you are at risk of developing Diabetic Retinopathy. Diabetic eye disease can result from having type 1 or type 2 diabetes.

The initial stages of diabetic eye disease may have minimal or no visual symptoms at all. Routine eye exams are important because early detection and treatment of diabetic eye disease will efficaciously diminish your chances of sustaining permanent vision loss.

If caught in time, new treatment options may help slow its progression and prevent further vision loss. People with diabetes are encouraged to schedule routine eye exams, even if symptoms are not noticeable.



Glaucoma is described as a group of eye diseases that causes damage to the optic nerve. It is often called the silent thief of sight, gradually reducing your vision without warning, and often without symptoms.

Glaucoma will eventually lead to blindness if it is left untreated. Many eye vision experts once thought that elevated pressure inside the eye was the leading cause of optic nerve damage.

Although elevated pressure is a risk factor, optometrists now have evidence that other factors must also be involved. This is because people with normal pressure can also experience vision loss from glaucoma.

Unfortunately, there is no cure for glaucoma, but there are medications and surgery available that can help slow the progression of vision loss. Early detection and regular eye exams are critical to slowing the progress of the disease.



Macular degeneration, which is known as AMD for short, is the deterioration of the center of the retina called the macula. It is a chronic, progressive disease that gradually destroys sharp central vision due to a deterioration of the macula. It consists of a tiny spot in the central portion of your retina comprised of millions of light-sensing cells that is responsible for our central vision and our ability to see color and fine details.

The two forms of AMD are called “dry” and “wet.” “Dry” is the most common type and has no known treatment. The other type- “wet,” is not as common and is treatable with laser procedures and can be diagnosed with genetic testing.

With regular eye exams, early diagnosis, and new treatment options, we can maintain visual acuity in most patients.
