Leukocoria

From WikiMD's Wellnesspedia

Leukocoria (also known as white pupillary reflex) is an abnormal white reflection from the retina of the eye. It is a medical sign for a number of conditions, primarily those affecting the retina or cornea, and is often detected in flash photography.

Causes[edit | edit source]

Leukocoria can be caused by a number of conditions, including:

  • Retinoblastoma: A rare type of eye cancer that usually develops in early childhood, typically before the age of 5.
  • Coats' disease: A rare condition characterized by abnormal development of the blood vessels in the retina.
  • Persistent hyperplastic primary vitreous (PHPV): A rare condition in which the blood vessels and fibrous tissue behind the lens of the eye do not regress normally during fetal development.
  • Cataract: A clouding of the lens in the eye that affects vision.
  • Retinopathy of prematurity (ROP): A potentially blinding eye disorder that primarily affects premature infants.

Diagnosis[edit | edit source]

Diagnosis of leukocoria is typically made through a comprehensive eye examination. This may include:

  • Visual acuity test: This test measures how well the patient sees at various distances.
  • Dilated eye exam: Drops are placed in the eyes to widen, or dilate, the pupils, allowing the doctor to examine the retina and optic nerve.
  • Tonometry: An instrument measures the pressure inside the eye to check for glaucoma.

Treatment[edit | edit source]

Treatment for leukocoria depends on the underlying cause and may include surgery, chemotherapy, laser therapy, or cryotherapy.
