The nurse is caring for a 64-year-old client.
History and Physical
Body System, Findings
General ,
The client reports a 24-hour history of blurred vision and redness in the left eye with a left-sided headache.
This evening, the client developed acute, severe pain in the left eye accompanied by occasional nausea and
vomiting. The client reports no use of systemic or topical eye medications. Medical history includes
osteoarthritis and hypercholesterolemia.
Eye, Ear, Nose, and Throat (EENT),
The client wears eyeglasses to correct farsighted vision. Right eye: pupil 2 mm and reactive to light,
conjunctiva clear. Left eye: pupil 4 mm and nonreactive to light with red conjunctiva. Bilateral lens opacity is noted.
Pulmonary,
Vital signs are RR 20 and SpO, 96% on room air. The lungs are clear to auscultation bilaterally.
Cardiovascular,
Vital signs are T 99 F (37.2 C), P 88, and BP 140/82.
Psychosocial,
The client reports a great deal of emotional stress following the recent death of the client's spouse that is accompanied by lack of sleep, poor appetite, and a 7.9-lb (3.6-kg) weight loss within the past month. The client takes diphenhydramine for sleep.

For each finding below, click to specify if the finding is consistent with the disease process of acute angle-closure glaucoma, cataracts, or macular degeneration. Each finding may support more than one disease process.

  • A. Blind spots
  • B. Opaque lens
  • C. Blurred vision
  • D. Unilateral headache
  • E. Conjunctival redness
  • F. Nausea and vomiting
  • G. Increased intraocular pressure
Correct Answer:

Rationale: Acute angle-closure glaucoma (ACG) is the sudden onset of increased intraocular pressure (IOP) due to impaired aqueous humor drainag
through the angle of the anterior chamber. Acute ACG typically occurs spontaneously but may be triggered by impaired aqueous outflow frol
pupillary dilation (eg, emotional excitement, medications (decongestants, anticholinergics, antihistamines], darkness). As IOP increases,
clients report seeing halos around lights and/or develop blurry vision, unilateral headache, conjunctival redness, and nausea and
vomiting. Increased IOP damages the optic nerve, and the cornea becomes edematous; therefore, light cannot travel effectively from the
cornea to the optic nerve, causing halos to be seen.
Cataracts are a slowly progressive pacification of the lens that results from oxidative damage. Refractive changes in the lens cause clients
to initially develop difficulty reading fine print because of the opaque lens. As the cataract progresses, clients develop painless, blurry visio
and have difficulty with nighttime driving because they see a glare and halos around lights. Halos and glare occur because light cannot
travel through the opacified lens effectively and instead disperses in various angles.
Age-related macular degeneration (AMD) is a progressive, incurable disease of the eye characterized by deterioration of the macula, the
central portion of the retina. This deterioration causes visual disturbances (wavy or blurred vision), blind spots, or loss of the central field
vision; peripheral vision remains intact. AMD has a vascular pathogenesis that is unrelated to increased IOP. Clients with AMD have a norm
cornea, lens, and optic nerve; therefore, halos are not seen.
