Remember back to the last time you experienced the birth of a baby. What was one of the most common questions people asked? Most likely, "WHAT COLOR ARE HIS EYES?,” was right up there.

What makes the color of our eyes appear as they do? What role do genetics play? What if you don’t like your eye color--can you change it? Are there any medications that can change the eye color? Get ready to explore the science behind eye color by starting at the beginning.......

Baby’s eye color can change. A baby can start out with blue eyes, for example, that change to brown as she ages. It’s all dependent on a brown pigment called melanin which develops as a child grows. The more melanin present, the darker the eye color. Brown eyes have the most pigment saturation, green/hazel eyes have less melanin, and blue eyes have the least pigment. The color of eyes is dependent upon genetics. Genetics are complicated, but generally speaking brown trumps blue if there is a brown-eyed parent. This is...

For over 40 years the standard surgical treatment for glaucoma was a procedure called a trabeculectomy.

In a trabeculectomy the ophthalmic surgeon would make a hole in the wall of eye to allow fluid from the inside of the eye to flow out of the eye and then get resorbed by the blood vessels in the conjunctiva (the mucous membrane that covers the white part of the eye).

This surgery often resulted in a large decrease in the Intraocular Pressure (IOP). Reducing the IOP is the goal of glaucoma surgery because multiple studies on glaucoma show that if you can reduce the pressure in glaucoma the progression of the disease slows.

The problem with trabeculectomy is although it frequently lowers the pressure it also has a fairly high complication and/or failure rate. This led to some reluctance to perform the procedure unless the glaucoma was severe, or the pressure was very high. As a result of those issues there has been a search during the last 40 years for something that had a...
