3. Glaucoma
What is a cataract? CORRECT ANSWERS Clouding of the crystalline lens, progressive
vision loss, uni or bilateral.
What is macular degeneration? CORRECT ANSWERS Most common visual problem in
the elderly causing blindness.
What is a glaucoma caused by? CORRECT ANSWERS increased intraocular pressure
What are glaucomas characterized by? CORRECT ANSWERS Excavation or cupping
of the optic disc, apoptic degeneration of retinal ganglion cells, corresponding vision.
What are the number 1 cause of preventable blindness? CORRECT ANSWERS
Cataracts.
,What causes cataracts? CORRECT ANSWERS Abnormal changes in lens proteins
resulting in their chemical and sstructural alteration, leading to loss of transparency.
Signs and symptoms of cataracts? CORRECT ANSWERS - imapired vision
- glare sensitivity
- difficulty with nighttime vision
- nearsightedness and monocular double vision.
Risk factorsfor cataracts? CORRECT ANSWERS - congenital
- trauma
- secondary to systemic diseasess (DM)
- topical, systemic or inhaled corticosteroid treatment.
- cigarette smoking
The most common cause of legal blindness in the elderly? CORRECT ANSWERS
Macular degeneration.
What is the dry form of macular degeneration? CORRECT ANSWERS Drusen: Madeup
of lipids and proteins ad renal pigment epithelium abnormalities.
What is the wet form of macular degeneration? CORRECT ANSWERS Wet
neovascular derangement (choroidal neovascular membrane formation).
Associating factors of macular degeneration? CORRECT ANSWERS - Race
- Family Hx
- HTN, CVS
- Light iris colour
- Cigarette smoking
Signs and Symptoms of Glaucoma? CORRECT ANSWERS - Primary open-angle
glaucoma
- Gradual loss of peripheral vision, usually in both eyes.
- Tunnel vision in advanced stages.
acute angle closure glaucoma CORRECT ANSWERS - Eye pain
- Nausea and vomiting
- Blurred vision
- Halos around the eye
-Ciliary flush
Risk factors for Glaucoma? CORRECT ANSWERS - Over 40
- Family Hx
- Farsighted/Nearsighted
- Had an eye injury
- DM
, - HTN
angle closure glaucoma CORRECT ANSWERS - Pupillary block
- Most likely to occur in mid-dilated states
- Results in a pressure gradient
- Use of anticholinergic or ssympathommimetic agents may trigger this crisis.
Conductive hearing loss? CORRECT ANSWERS External or middle ear dysfunction.
Sensory hearing loss results from? CORRECT ANSWERS Deterioration or atrophy of
the cochlea.
Secondary sensorineural impairment can be due to (4)? CORRECT ANSWERS 1.
Trauma
2. Infection
3. Autoimmune disease
4. Vascular diseases
Rinne Test (Conduction) when normal? CORRECT ANSWERS Air conduction lasts
longer than bone conduction.
Rinne Test (Conduction) when conductive? CORRECT ANSWERS Bone conduction
lassts longer or is equal to air conduction.
Rinne Test (Conduction) when senorineural? CORRECT ANSWERS Air conduction
lastss longer than bone conduction.
Weber test (localized) when normal? CORRECT ANSWERS Sound is equal bilaterally.
Weber test (localized) when conductive? CORRECT ANSWERS Sound lateralizes to
impaired ear.
Weber test (localized) when senorineural? CORRECT ANSWERS Sound lateralizes to
good ear.
Management of hearing loss? CORRECT ANSWERS - Speak directly and face the
person: Lower voice
- Clear items away from mouth.
- Hearing aids.
Menieres's disease? CORRECT ANSWERS A disorder of the inner ear that can lead to
dizzy spells (vertigo) and hearing loss. In most cases, affects only one ear. Can occur at
any age, but it usually starts between young and middle-aged adulthood.
Fall definition? CORRECT ANSWERS Defined as an event which results in aperson
coming to restinadvertently on theground or floor or other lower level.
