Study Notes

Ocular Manifestations and Conditions

  • Diabetes-related ocular manifestation: Cataract is a common ocular manifestation of diabetes related to the lens.
  • Laser for posterior capsulotomy: Neodymium-YAG (Nd-YAG) laser is commonly used for posterior capsulotomy after cataract surgery.
  • Vitamin A deficiency and ocular condition: Xerosis (dryness) of the conjunctiva is an ocular condition that can occur due to vitamin A deficiency. This can progress to keratomalacia in severe cases.
  • Systemic lupus erythematosus ocular manifestation: Cotton-wool spots are a common ocular manifestation of systemic lupus erythematosus.
  • Hyperglycemia and refractive changes: Myopia is a condition associated with hyperglycemia causing changes in refraction.
  • Blepharitis characteristics: Recurrent styes and chalazia are characteristics of blepharitis.
  • Neodymium-YAG laser indication: Posterior capsulotomy is the most common indication for using the Neodymium-YAG laser.
  • Retinal arteriolar occlusions and systemic disease: Diabetes is a systemic disease that can produce retinal arteriolar occlusions. Sickle-cell anemia can also cause retinal arteriolar occlusions.
  • Lead poisoning ocular manifestation: Optic atrophy can occur due to chronic lead poisoning.
  • Vitamin A deficiency and keratomalacia: Vitamin A deficiency can lead to keratomalacia.
