visual impairment resulting from the retina becoming separated from the choroid in the back of the eye from trauma, fluid accumulation, or age related.
Retinal Detachment Symptoms/ Nursing Care
Blurred Vision, Flashes of Light, Visual Floaters, A veil-like loss of vision.- Place in dependent position. Post-op care: place pt. on abdomen with head turned with operative eye upward for several days until gas/oil is absorbed. Keep head bowed when walking. Avoid activities like reading.
Nearsightedness- correct Concave lens
Farsightedness- correct Convex lens
Lens losses elasticity- unable to focus on close objects- age related
uneven curvature- eye defect which prevents proper focus

Objects that irritate eyes- Cover both eyes with cups. ONLY can be removed by Ophthalmologist.
Lacerations and Penetrating Eye Injury-Nursing Care
Medical Emergency- Affects Cornea- IV antibiotics and Surgery.
Ocular Melanoma-Nursing Care
Cancer of the eye- S/S: blurred vision, decreased visual acuity, intraocular pressure, change in iris color, retinal detachment.-Tx: Radiation or enucleation (removal of eyeball).
Otitis Externa- Nursing Care
"Swimmers Ear"- caused from hot, humid environment, allergic reaction like hair spray, earrings,or organisms like bacteria/fungi, most infections are from strep.- Do not clean ears, avoid water entering ears.
Otitis Media- Nursing Care
Infection of the middle ear- S/S:fever, pain, vomiting, anorexia. Relief in ear pressure may be a result rupture of tympanic membrane.
How to instill ear drops
Under 3 yrs- Pinna Down and Back/ Over 3 yrs- Pinna Up and Back, gently massage ear.
inflammation of one of the mastoid bones; usually an extension of otitis media characterized by earache, fever, headache, and malaise.
Mastoiditis Nursing Care
IV antibiotics, Mastoidectomy/ Tympanoplasty: Observe for damage to 6th/7th cranial nerve. Notify doctor of facial paralysis or abnormal eye movements, Blow nose one at a time, cough with mouth open, avoid bending, avoid water in ears.
Menieres Disease- Nursing Care
Inner ear- S/S: Vertigo, Tinnitus, decrease ability to hear low tones. Tx: Weber test, Audiogram, "Pikes Peak" pattern, Salt/Fluid restriction, no smoking. -Change position slowly.
Benign Tumor involving 8th cranial nerve damaging Cerebellum (regulation and coordination of movement, posture, and balance). S/S: Sensorineural Hearing Loss, Vertigo, Tinnitus. Tx: Craniotomy.
Sensorineural Hearing Loss
damage to inner ear- permanent hearing loss.
hereditary disorder in which hardening of the labyrinth of the inner ear causes tinnitus and eventual deafness- Conductive Hearing Loss.- Weber Test- Tx: Stapedectomy .
Test done by placing the stem of a vibrating tuning fork on the midline of the head and having the patient indicate in which ear the tone can be heard.
a graphical representation of a person's auditory sensitivity to sound
Stapedectomy- Nursing Care
Surgical removal of the top portion of the stapes bone and the insertion of a small prosthetic device known as a piston that conducts sound vibrations to the inner ear.- Avoid activities with ear pressure, Avoid crowds, Report abnormal facial sensation, Avoid water in ear.
Presbycusis- Nursing Care
Gradual loss of sensorineural hearing that occurs as the body ages, cant hear high frequencies- Avoid loud sounds, Diet in Vitamin B9/B12, Audiometry Test: measure decibel (Pure-tone= Music stimulus)/ (Speech=spoken words stimulus)
Hear Loss Patient Nursing Care
Stand if front of pt, eliminate background noise, use other communicating techniques like writing board, Try to speak in lower tones. Hearing aid: avoid electrical devices (magnet).
display consisting of a printed card with letters and numbers in lines of decreasing size
Ishihara Polychromatic Chart
Color chart to test for color blindness- cannot distinguish red from green or blue from yellow.
test to assess central vision and to assist in the diagnosis of age-related macular degeneration
Used to detect glaucoma-test to measure the pressure inside your eyes and a lamp is moved forward until the tip of the tonometer just touches the cornea.
OcuCaine, Ak-Taine (proparacaine HCL), Pontocaine (tetracaine HCL, cocaine Hcl)- avoid rubbing or touching eye.
OcuPred (prednisolone acetate), Dexotic (dexaethasone), Fluor-Op (liquifilim)- reduces swelling/inflammtion-shake before using, assess for corneal ulceration.
Tobrex (tobramycin), Ilotycin (erythromycin), Ocuflox (ofloxacin)- interferes with bacteria- remove exudates from eye before giving.
Alpha 2 Adrenergic Agonist
Alphagan (brimonidine tartrate)- reduced intraocular pressure- do not give with MAOI's, wait 15 minutes before replacing contacts.
Beta Adrenergic Blockers
Betoptic (betaxolol), Ocupress (carteolol Hcl), Timoptic (timolol)- reduced intraocular pressure by decreasing aqueous humor- do not give to pulmonary disease pts, monitor blood glucose.
Miotics (Direct Acting)
Carboptic (carbachol), Isopto Carpine (pilocarpine)- reduces intraocular pressure by constricting pupils- do not give to corneal abrasions pts, do not increase dosages.
Miotics (Cholinesterase Inhibitors)
Humorsol (demecarium bromide), Phospholine (echothiophate iodide)- reduce intraocular pressure by constricting pupils- Asses intraocular pressure frequently
Carbonic Anhydrase Inhibitors
Trusopt (dorzolamide), Azopt (brinzolamide)- decrease aqueous humor to reduce pressure in eye- do not give to pts. Who are sensitive to Sulfonamides, remove contact lens before using for 15 minutes before reinserting.
