Basic Eye Information

Dr. Burke is one of Cincinnati's most trusted resources concerning eye care for children.

Is the eye just like a camera?

Although often compared to a camera, the eye is far more complicated and complex. It not only focuses and takes “pictures” but it also tracks and follows the target then processes this information seamlessly with the brain which ultimately allows us to be conscious of what we “see”.

Why do we say that our eyes are so complex?

Our eyes are indeed a very complex sensory organ that is an extremely important part of what we call the visual system. In order for us to “see”, first there must be light rays emitted from or be reflected off of a target. As these light rays enter and pass through the eye, an image is focused by the cornea and lens (and glasses if worn) and projected onto the retina. The retina is at the back of eye and consists of millions of light receptive cells that convert these focused light rays into electrical signals that are transmitted through a multilayered system into our brain. Once the brain receives and processes these signals, we perceive an image. It is at that moment that vision has occurred and we say "I see".

What does that mean to have your visual acuity measured?

Visual acuity testing is a measurement of a person's ability to see in sharp, clear, and fine detail. Visual acuity expressed as “20/20” is what is referred to as normal vision.

What are the four ways one commonly evaluates our visual abilities?

The 4 parts of the visual system that are commonly evaluated are central vision, peripheral vision,
3-D vision or depth perception, and color vision.

What is central vision?

Central vision is the ability to clearly see objects at which one is looking.

What is peripheral vision?

Peripheral vision is the ability to see shapes and forms that surround the central vision target. Peripheral vision does not give us a detailed vision.

What is 3-D vision?

3-D vision or depth perception is the ability of our two eyes to view one object from slightly different angles which the brain blends these two views giving us a perception of dimension and position in space of the object at which we are looking.

What is color vision?

There are light receptive cells in our retina that are called cones. In the normal eye there are 3 different kinds of cones, each perceiving or responding to different wave lengths of light. Typically we refer to these as red, green, and blue cones. It is through the variable stimulation of these cones that allow the human to differentiate over a million shades of color.
Additional Information

Why does the eye have its own field of medicine?

With so many vital components of the eye and so many aspects to visual ability, it is no wonder that so much effort and so many different kinds of professionals are involved in preserving eyesight and maintaining eye health.

A few kind words from our Patients...

  • Dr Burke, I just want to take a moment to thank you for everything you have done for our daughter. From day one you have been phenomenal; always taking your time and making sure she was comfortable with you and your procedures. She has spent the last week and a half telling everyone in the most excited tone ever,”Dr.Burke fixed my eye!” You may see a spike in referrals among three year olds (haha!!). She's your biggest fan! Thanks for being so wonderful!
  • Dr Burke, We wanted to thank you for the special care you have given our children Winston and Norah. Our kids loved coming to see you and we appreciate the special attention you give to each one. We feel very confident and comfortable in your care. Thanks Again!
  • Dr Burke , Let me first say how fortunate Willy (my son) and I have been to have had you for a surgeon and doctor. You have a gift in making people feel so comfortable (not all people/ or doctors have that you know)! I remember the time Willy brought in a fake rubber rat (around Halloween) to "scare," you, and you walked in and threw your file of papers up in the air-it was great fun! Thanks for Everything!
  • Dr Burke examined my son’s eyes and spoke with him. You told me,"Andrew’s eyes are fine. Andrew is dyslexic." My response was: “What do we do?” You suggested the book ‘Overcoming Dyslexia,’ by Sally Shaywitz. My husband and I read the book and began practicing the principles advised. I will not lie, it was a struggle and an enormous amount of work. Within a year, Andrew’s Reading and self-esteem improved tremendously. Thank You.
  • Dr Burke, We cannot thank you enough for fixing Corey's eye. He is so excited to have a normal looking eye and seeing normal. You have given him the ability to be successful at school and in life. And he hopes one day, "He can make miracles happen just like you!" We are so grateful. Thank You!
  • Dr Burke, First, thank you for your diagnosis and comfort you provided my wife and me with respect to our daughter Gwyneth. Our family physician's opinions mean the world to us, and she says you're the best. Your office is very fun, your staff is wonderfully pleasant and professional, and seeing you work was indeed a privilege.
  • Dr Burke, Thank you for enabling me to clearly see just how beautiful this world is, again. I am very thankful for your healing skills, but most appreciative of your exceptional thoughtfulness. Thank you for giving me a part of your vacation time-truly a gift. My fourth graders and I will benefit greatly from it. Most Appreciatively,
  • Dr Burke is my hero! Dr. Burke is the most compassionate doctor I have ever met. I was born cross-eyed and had an eye surgery on both eyes as an infant and another surgery on one as a child. Because of my eye muscle problems, I have always been seen by a doctor with Dr. Burke’s specialties but none of my previous doctors were as caring and kind as Dr. Burke.
  • Dr Burke, I wanted to give you an update on Elizabeth who was under your care from age 4 until a few years ago. When we left your office after she first saw you, she looked up and said, "I want to be a doctor just like Dr. Burke." Elizabeth is now in her third year of medical school and is still interested in pediatric ophthalmology. She started an ophthalmology club for the medical students and she volunteers at different events doing vision checks. You're such an inspiration to her she has said she plans on being a doctor, "Just like Dr. Burke."
