Hypertension Anthony Dima-ala, SNPhA
Hypertension Statistics • 67 million Americans, age >20 have elevated BP (BP > 140/90) • More than half of these patients do not have their BP under control • More than 348,000 American deaths in 2009 included high blood pressure as a primary or contributing cause • Almost 30% of American adults have pre-hypertension “High Blood Pressure Facts.” Center of Disease Prevention. Web. 19 Jan. 2014.
Why a “silent killer?” • Most patients do not have symptoms or warning signs • Most important physical finding is elevated BP

Glaucoma National Optometric Student Association (NOSA)
What is Glaucoma? Glaucoma is a group of eye disorders leading to progressive damage to the optic nerve, and is characterized by loss of nerve tissue resulting in loss of vision. Definition taken from American Optometric Association Website
Cranial Nerve II The optic nerve is a bundle of about one million individual nerve fibers and transmits the visual signals from the eye to the brain.
Glaucoma Statistics Glaucoma is the second leading cause of blindness in the U.S. Information from National Eye Institute
Consequences of Glaucoma Initially affects peripheral vision, but can advance to central vision loss. If left untreated, glaucoma can lead to significant loss of vision in both eyes, and may even lead to permanent blindness.
Risk Factors • Age—People over age 60 are at increased risk for the disease. For African Americans, however, the increase in risk begins after age 40. The risk of developing glaucoma increases slightly with each year of age. • Race—African Americans are significantly more likely to get glaucoma than are Caucasians, and they are much more likely to suffer permanent vision loss as a result. People of Asian descent are at higher risk of angle-closure glaucoma and those of Japanese descent are more prone to low-tension glaucoma. • Family history of glaucoma—Having a family history of glaucoma increases the risk of developing glaucoma. • Corticosteroid use—Using corticosteroids for prolonged periods of time appears to put some people at risk of getting secondary glaucoma.
Glaucoma Drug Modalities • Outflow Enhancement • Prostaglandin Analogs (25-35%) • Miotics • Epinephrine • Aqueous Supression • Beta Blockers (25-30%) • Alpha-2 Adrenergic Agonists (20-25%) • Carbonic Anydrase Inhibitors (15-20%)
Prostaglandins Mechanism of Action: • Interact on Fp receptors on ciliary body that causes rearrangement of fibers and enhances outflow. This increases uvealscleral outflow in between the muscle fibers Ocular Side Effects: • Conjunctival injection • Increased pigmentation of eyelashes, periorbital skin tissue, iris • “sunken sulcus syndrome”, perioribital fat dissipates Contraindications: • Uveitis, ocular simplex, CME, concurrent use of miotics
Beta Blockers Mechanism of Action: • Blocks Beta 2 receptors on ciliary body epithelial cells and decrease aqueous production Ocular Side Effects: • Stinging • Can induce dry eye because of decreased tear production Contraindications: • Asthma, COPD, CHF, pregnancy, resting bradycardia
Alpha Agonists Mechanism of Action: • Prevent NorE release to target tissue on Beta receptors which in turn causes decreased aqueous production • May also increase uvealscleral outflow Ocular Side Effects: • Ocular vasoconstriction • Follicular conjunctivitis • Contact blepharoconjuncitivitis Contraindications: • Pediatric glaucoma, people using MOA antidepressants
Carbonic Anhydrase Inhibitors Mechanism of Action: • Inhibits……Carbonic anhydrase • Reduces ionic bicarbonate formation that reduces aqueous production Ocular Side Effects: • Stinging • Foreign body sensation • Can diminish corneal endothelial vitality Contraindications: • Fuch’s Endothelial Dystrophy • Renal and liver disease • COPD • Pregnancy • Sulfa allergy
