Glaucoma, Macular degeneration, Cataracts
➔ Describe the clinical manifestations, diagnostic studies, and treatment options of
the patient with sensory impairments.
➔ Discuss the role of complementary and alternative medicine in patients with
sensory impairments.
➔ Identify nursing interventions used in the care of a patient with sensory
impairments.
➔ Discuss teaching strategies for patients with sensory impairments.
➔ Discuss the pharmacological interventions used to treat and the nursing
implications associated with a patients who have a sensory impairments.
➔ Apply the nursing process/clinical judgment model in providing evidence-based,
culturally competent care across the lifespan for patients with a sensory
impairments.
, Glaucoma
Pathophysiology: Expected IOP reference range: 10 - 21 mm/Hg
➔ Intraocular hypertension damages the optic nerve
leading to progressive PERIPHERAL visual field loss. Risk Factors:
➔ Aqueous humor drainage pathway becomes ➔ Open Angle: ⬆ age, African descent, family hx
partially/completely blocked leading to fluid not ➔ Closed Angle: ⬆ age, female asian-descent,
draining completely which leads to pressure hyperopia medications (mydriatic eye drops),
building up, thus causing intraocular hypertension pseudoexfoliation
➔ Intraocular pressure (IOP) increases causing ➔ General: Infection, Tumor, Diabetes Mellitus, HTN,
continued damage to optic nerve leading to Eye trauma, Severe myopia (nearsightedness),
ganglion cell loss leading to loss of central vision. Retinal detachment
TYPES: Expected Findings:
Clinical Ma
● Open-Angle Glaucoma: more common; refers to Open-angle glaucoma: Closed-angle glaucoma:
the angle between cornea, iris and sclera. ⬆ ➔ Rapid IOP increase (30 or >)
➔ Often asymptomatic ➔ Severe eye pain, redness,
aqueous production/ ⬇outflow, leading to ➔ Mild eye pain
increased IOP. blurry/vision loss, colored
➔ Loss of PERIPHERAL VISION halos around light, pupils
● Closed-Angle Glaucoma: acute rapid buildup of ➔ Decreased accommodation non-reactive to light
pressure; angle between iris and sclera suddenly ➔ Halos around light
closes, causing sudden ⬆ IOP leading to optic ➔ Headache/nausea
➔ IOP > 21 (usually 22 - 32) ➔ Conjunctival redness, corneal
nerve damage.
edema
➔ Photophobia
