Coloboma of Optic Nerve refers to a rare eye disorder that is characterized by a hole in the optic nerve. The optic nerve sends visual information from the eye to the brain for interpretation. Hence, individuals with this disorder have vision problems, specifically being unable to process or understand what their eyes see. The severity of the disorder depends on the size of the hole in the optic nerve. Vision problems can affect an individual significantly, inhibiting their ability to perform day-to-day tasks. The condition is often diagnosed during childhood, since individuals are born with the defect. Eye specialists often diagnose this condition after deducing a hole in the optic nerve from eye examinations or brain scans. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Eye and brain specialists may suggest patients undergo surgery to repair the hole in the optic nerve.
