Flashcards on Impaired Vision and Eye Health

Front

Risk factors for impaired vision include age over 50 years, smoking, genetics, being Caucasian, and screen time exceeding 4 hours.

Back

These factors can negatively affect daily living activities, and there is debate about the effectiveness of blue-blocking glasses in reducing eye strain.

Sighted Guide Technique for nursing management of impaired vision.

Back

Have the patient hold onto your arm above the elbow and walk about a half step behind you.

Front

Fall risk precautions for patients with impaired vision.

Back

Implement measures to prevent falls, such as removing hazards and ensuring proper lighting.

Front

Increased intraocular pressure (IOP) and its impact on vision.

Back

IOP greater than 21 mm Hg can cause optic nerve damage and is a leading cause of blindness in the U.S.

Front

Risk factors for glaucoma.

Back

Glaucoma is more common in individuals over 60 years, men, those with diabetes, cardiovascular disease, prolonged corticosteroid use, and certain ethnic groups such as African American, Black, Hispanic, and Asian populations.

Front

Back

Glaucoma is progressive, asymptomatic, and irreversible, often referred to as the "silent thief of sight."

Front

Late symptoms of glaucoma.

Back

Halos around lights, blurred vision, and loss of peripheral vision.

Front

Beta-blocker eye drops for glaucoma management.

Back

These drops decrease aqueous production, reducing IOP, and must be taken exactly as scheduled.

Front

Importance of regular eye exams for glaucoma detection.

Back

Eye exams every 1-2 years are crucial for early detection and management of glaucoma.

Front

Most common cause of treatable blindness.

Back

Cataracts, characterized by cloudiness (opacity) of the eye lens, cause painless blurry vision.
