Lacrimal artery insufficiency

Lacrimal artery insufficiency is a condition where the lacrimal artery, which supplies blood to the lacrimal gland (responsible for tear production), does not provide enough blood flow. This can lead to various issues related to eye health and tear production.

Types

  1. Primary Insufficiency: Caused by congenital or developmental issues.
  2. Secondary Insufficiency: Resulting from other conditions such as trauma, inflammation, or surgery.

Causes

  1. Atherosclerosis: Hardening of the arteries.
  2. Diabetes: High blood sugar can damage blood vessels.
  3. Hypertension: High blood pressure can strain arteries.
  4. Trauma: Injury to the eye or head.
  5. Inflammation: Conditions like vasculitis.
  6. Autoimmune Diseases: Such as lupus or rheumatoid arthritis.
  7. Tumors: Pressure on the artery from growths.
  8. Infections: Such as orbital cellulitis.
  9. Surgical Complications: Post-operative damage.
  10. Aging: Natural wear and tear of blood vessels.
  11. Radiation Therapy: Damage from cancer treatments.
  12. Smoking: Contributes to vascular problems.
  13. High Cholesterol: Can block arteries.
  14. Thrombosis: Blood clots in the artery.
  15. Congenital Defects: Abnormalities from birth.
