Diabetes and cataract #bestdiabetologistinperambur #bestcardiologistinperambur

Diabetic cataract is a rapid onset clouding of eyes' lens due to high blood sugar, which leads to sorbitol accumulation, lens swelling, and damage. People with diabetes develop cataracts earlier and more often
. Key symptoms include blurred vision, halos, poor night vision, and frequent prescription changes
Key Aspects of Diabetic Cataracts:
  • Pathogenesis: High glucose levels convert to sorbitol, causing osmotic damage to lens fibers.
  • Types: Often manifests as posterior subcapsular cataracts, or "snowflake" cataracts in younger type 1 patients.
  • Risk Factors: Longer duration of diabetes, poor glycemic control (HbA1c levels), and coexisting complications like retinopathy.
  • Management: While early metabolic changes can sometimes be reversed, surgery is generally needed to restore vision.
  • Surgery and Diabetes: Cataract surgery is highly effective, but blood sugar should be well-managed to prevent post-operative complications
Symptoms of Diabetic Cataract
  • Blurry or cloudy vision
  • Colors appearing faded or yellow
  • Difficulty seeing at night
  • Sensitivity to light/glare
  • Halos around lights
  • Frequent changes in eyeglass prescription
Prevention and Treatment
  1. Strict Blood Sugar Management: Consistent blood sugar control is crucial to slow or prevent progression.
  2. Regular Eye Exams: Individuals with diabetes should have comprehensive dilated eye exams at least annually.
  3. Surgery: When vision is impaired, surgery involves removing the cloudy lens and replacing it with an intraocular lens
