A doctor uses a slit-lamp to examine a patient's cortical cataract.

Definition

1. Noun:
   • A type of cataract affecting the lens cortex: A "cortical cataract" is an opacity or clouding of the eye's natural lens that specifically originates in and affects the outer layer, or cortex, of the lens. This type of cataract often appears as white, wedge-shaped opacities or spokes that start at the periphery of the lens and may extend toward the center, potentially interfering with vision.

Usage Examples

• Noun:
  • The ophthalmologist diagnosed the patient with a cortical cataract in the left eye.
  • Cortical cataracts can cause glare and problems with contrast sensitivity.
  • The progression of the cortical cataract was monitored through annual eye exams.

Advanced Usage

• Clinical description: In medical contexts, a cortical cataract may be described by its specific morphology, such as "spoke-like" or "cuneiform" opacities.
  • The slit-lamp examination revealed classic cuneiform opacities indicative of a cortical cataract.
