AMBLYOPIA

• Definition = impairment of vision in an eye without a detectable organic lesion.
  • aka "lazy eye," the implication being that an image is appropriately focused on the retina and relayed to the visual cortex but not processed.
  • One practical definition is a discrepancy of 2 or more lines between the eyes on Snellen testing, in the presence of a condition known to cause amblyopia
• Associated conditions
  • Anisometropia
  • Strabismus (eyes not pointing in the same direction; Cover-Uncover test can help detect)
  • Ametropia
  • Others
• Traditionally treated by patching the "good" eye; alternatively atropine drops in the "good" eye
