Coloboma of Lens Ala Nasi refers to a rare eye disorder that is characterized by a hole in the lens of the eye, and a gap in the flaps around the nostrils. The lens is vital to focusing light in vision, and ensuring images individuals see are clear. Flaps in nostrils are important for directing air in the right direction into the lungs. Hence, individuals with this disorder have vision and breathing problems. The severity of the disorder depends on the size of the lens hole and nostril flap gap. Vision and breathing 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 defects. Doctors often diagnose this condition after observing holes in the lens and nostril flaps via thorough examinations. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Specialists may suggest patients undergo surgery to fix lens and nostril problems. An artificial lens may be used to replace the faulty lens.
