Assessment and Management of Visual Problems
Visual System - ANS Part of the Central Nervous System (CNS)
Orbit - ANS Eye sockets composed of seven bones and muscles, nerves, blood vessels, and fat
Optic Canal - ANS Opening in the orbit for arteries, veins, and nerves
Extraocular Muscles - ANS Six muscles responsible for eye movement
Ocular Adnexa - ANS Includes eyebrows, eyelids, eyelashes, and lacrimal system
Lacrimal System - ANS Responsible for tear production and drainage
Cornea - ANS Outer layer of the eyeball that allows entry of light
Iris - ANS Gives the eye color and controls the amount of light entering
Aqueous Humor - ANS Clear fluid in the anterior chamber that nourishes nonvascular structures
Lens - ANS Biconvex structure behind the iris that changes shape to focus light
Vitreous Humor - ANS Transparent gel-like substance filling the posterior cavity
Retina - ANS Converts images to neural signals for the brain to process as vision
Photoreceptors - ANS Rods and cones that convert light to neural signals
Optic Nerve - ANS Transmits visual information from the retina to the brain
Visual Pathway - ANS Route light takes from cornea to occipital cortex for processing
, Gerontologic Considerations - ANS Effects of aging on visual system structures
Benign Changes - ANS Non-harmful alterations in visual system with age
Severely Compromised Visual Acuity - ANS Significantly reduced clarity of vision
Visual System Assessment Complexity - ANS Varies from simple to intricate evaluations
Underlying Concerns - ANS Issues not immediately apparent to patients
Patient-Specific Assessment - ANS Tailored evaluation for each individual
Sensory deficit - ANS A clinical problem related to visual impairment, affecting the ability to receive
or interpret sensory information.
Impaired role performance - ANS A clinical problem related to visual impairment, affecting the ability
to fulfill expected societal roles.
Successful adjustment to impairment - ANS Goal in nursing management of visual impairment,
aiming for the patient to adapt well to their visual challenges.
Responsible eye care - ANS Part of the implementation phase in nursing management, focusing on
preventive measures and seeking appropriate healthcare for eye health.
Visual substitution techniques - ANS Methods like braille, audio books, canes, and guide dogs used to
enhance visual function in individuals with visual impairment.
Non-24-Hour Sleep-Wake Disorder - ANS A circadian rhythm sleep disorder caused by a lack of light,
leading to trouble falling and staying asleep.
Melatonin or melatonin receptor agonist - ANS Treatment for Non-24-Hour Sleep-Wake Disorder to
regulate sleep patterns.
