Coloboma of Iris refers to a rare eye disorder that is characterized by a hole in the iris (colored portion) of the eye. This hole in the iris, will often make it appear as if the pupil, or central black area of the eye, is oddly shaped. Irises are vital to controlling the amount of light entering the eye, ensuring the appropriate brightness and focus of the image individuals see. Hence, individuals with this disorder have severe vision problems, specifically being unable to see images clearly. The severity of the disorder depends on the size of the hole in the iris. Vision problems can affect an individual significantly, inhibiting their ability to perform day-to-day tasks. The condition is often diagnosed during childhood, since most individuals are born with the defect. Eye specialists often diagnose this condition after observing a hole in the iris via eye examinations. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Eye specialists may suggest patients undergo surgery to fix iris problems.
