Eye Exams in Houston, Texas

Your comprehensive eye exam at Houston’s Diagnostic Eye Center will include a thorough evaluation of all parts of the visual and ocular system. Some patients can have eye diseases without experiencing any symptoms, and a complete eye exam can help detect these conditions. Our Houston Ophthalmologists Dr. Marc Sanders and Dr. Andrew Salem, and Houston Optometrists Dr. Aric Welton, Dr. Stephanie Lozano, and Dr. Elizabeth Bell are committed to providing the best care for your eyes.

Did you know that many systemic conditions, like diabetes and high blood pressure, are sometimes first diagnosed through an eye exam? When we examine the retina, we are able to see the small blood vessels in the back of the eye. In this case, the eyes truly are the window to the soul, because these blood vessels can let us know how your overall health is doing. If there is bleeding or leaking of these vessels, that can indicate a more serious condition going on throughout the body.

We can also diagnose things like a stroke, cancer, autoimmune conditions, and sexually transmitted diseases, just by doing a comprehensive eye exam. Often times patients have no idea they have these conditions, and in some cases, an eye exam can be life-saving.


Your comprehensive eye exam includes evaluation of the following:

Eye Exam

  • Visual acuity
  • Need for eyeglasses or contact lenses
  • Coordination and function of eye muscles
  • Peripheral (or side) vision
  • Pupillary response
  • Accommodative response (focusing ability of the eye)
  • Intraocular pressure (pressure inside the eye)
  • Eyelid health and function
  • Anterior segment of the eye, including the cornea, conjunctiva, iris, and lens
  • Posterior segment of the eye, including the retina and optic nerve (this usually involves the use of eye drops to dilate your eyes)
  • Presence of ocular diseases, including glaucoma, macular degeneration, dry eye disease, amblyopia (lazy eye), and diabetic eye disease

What should I bring to my eye exam?

Please bring all currently used glasses for your appointment. Even if your glasses are broken, we can generally still measure them to determine if there has been a change in your prescription. If you wear contact lenses, please bring your contact lens boxes or packages so we know exactly what lenses you have been wearing.

Be sure to bring a list of all current medications, including any vitamins or eye drops, as well as your insurance cards and a form of identification.

Why do I need to have my eyes dilated during my eye exam?

By dilating your eyes, we are able to thoroughly assess the health of the posterior segment of the eye, including the retina and optic nerve. This allows us to detect diseases like glaucoma, macular degeneration, and diabetic eye disease. Even if your vision is 20/20, you could still have a serious sight-threatening condition that may not be able to be diagnosed without a dilated eye exam. Dilation is also helpful in verifying glasses prescriptions for some patients, especially for children and those who are far-sighted.

Dilation results in light sensitivity and blurred vision at near, but the effects typically wear off after approximately three to four hours. Most people feel comfortable driving after having their eyes dilated, but you are always welcome to bring a driver with you if you prefer.
