Lens & Cataract



















Mature Cataract

  • Clinical features:
    • Symptoms: usually severe decrease in vision.
    • Signs:
      • Total opacification of the lens capsule, cortex and the nucleus
      • May progress to hypermature cataract, which is characterized by wrinkling of the capsule due to liquefied lens cortex and Morgagnian cataract (sinking of lens nucleus inferiorly within the capsule)
      • May be complicated with phacolytic glaucoma.
  • Work-up:
    • Check pupils for relative afferent pupillary defect and retinal function assessment.
    • B-scan ultrasound study to rule out posterior segment pathologies.
  • Management:
    • Control of intraocular pressure if elevated.
    • Surgical removal.
