Sensorineural Disorders
Terms to remember
Astigmatism Blurred vision due to irregular
shape of the cornea or lens that prevents proper focusing of light on the retina
Decibel (dB) Measurement of intensity of
sound waves Emmetropia
Normal vision, perfect vision Hyperopia
farsightedness
Legally blind Vision of 20/200 that cannot be
improved with corrective lenses Myopia
nearsightedness Mydriatic
Causes pupillary dilation Presbycussis
Age-related sensorineural hearing loss
Presbyopia Difficulty in focusing on near
objects due to loss of flexibility of the crystalline lens due to aging
Essential Procedures
Tonometry
To measure intraocular pressure (IOP)
Normal: 12-21 mmHg (Mosby); 10-20 mmHg (Brunner)
Eyes
Flashback!
Cataract
Main problem Opacity of the lens usually associated with aging, prolonged intake of
steroids and chromosomal aberrations Initial Manifestation
Painless blurring of vision Laboratory Data
Slit lamp test reveals milky white color of the pupils Intervention
Prepare the patient for surgery. Post-op instruct the client to avoid activities that require bending
Report sudden eye pain Avoid lifting and rapid head movements
Glaucoma Main Problem
Increased intraocular pressure due to accumulation of aqueous humor
Initial Manifestation Tunnel Vision
Laboratory data Tonometry reading
of 25 mmHg and above
Intervention Explain to the client that
glaucoma CANNOT be cured but can be controlled
Instruct the client to avoid lifting, pushing, emotional upsets and exposure to URTI: may increase IOP
Instruct the client to avoid products that contains atropine sulfate
Explain to the client that trabeculoplasty involves creation of an opening to increase outflow
Retinal Detachment Main Problem
Separation of the sensory retina from the pigment epithelium of the retina Initial Manifestation
Visual floaters described by clients as “cobwebs” or “curtains” in the eyes; flashing of lights and visual field loss
Laboratory Data Eye exam Opthalmoscopy
Interventions Priority is immediate bed rest Position the client with the affected side towards the bed Avoid coughing, sneezing, sudden eye movement and straining Prepare the client for eye surgery
Ears
Flashback!!!
Essential Procedures
Rinne’s Test
To differentiate between conductive and sensorineural hearing losses
Weber’s Test
To detect the presence of unilateral hearing loss
Otosclerosis
Main Problem Overgrowth of spongy bones in the middle ear
Manifestation Tinnitus Conductive Hearing loss
Laboratory data Audiometry reveals hearing loss
Intervention Prepare the client for surgery After surgery, instruct the client to void blowing the nose,
diving, smoking, flying in small plane
Meniere’s Disease A.K.A.
– Endolymphatic hydrops
Main problem Dilation of the
endolymphatic system causing degeneration of the vestibular and cochlear cells in the inner ear.
Affects CN VIII Manifestation
Vertigo Tinnitus Sensorineural hearing loss
Interventions Priority: PROMOTE
CLIENT SAFETY Keep the client in supine
position during attack of vertigo
Maintain low sodium diet Encourage the client to
stop smoking Keep the room dark
when photophobia is present
