Cataract
Cortical Cataract

  • The most common form of senile cataract.
  • Clinical features:
    • Symptoms:
      • Minimal symptoms of decrease in visual acuity
      • Mild to severe glare and night vision difficulties and may impair driving
      • When the lens opacities are in the visual axis, patients may complain of monocular diplopia
    • Signs:
      • The opacities are located in the cortical layer and initially develop in the lower portion of the lens
      • Early stage cortical cataract demonstrates water clefts and vacuoles, which may change over time resulting in irreversible opacities
      • In a more advanced stage, spoke-like or wedge-shaped peripheral opacities progress circumferentially, initially sparing the clear central axis of the lens.
