    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.
