Study Notes
Cataracts
- Opacity or cloudiness of the lens develops in one or both eyes
- Decreased visual acuity is directly proportional to cataract density
- Most common causes are preventable
- Can progress to blindness
Risk Factors for Cataracts
- Age
- Cigarette smoking
- Long-term corticosteroid use
- Excessive sunlight exposure
Cataract Symptoms
- Painless, blurry vision
- Glare sensitivity at night
- Diplopia (Double Vision)
- Dimness or trouble seeing in low light
- Color Shifts in color perception
Cataract Diagnostic Testing
- Snellen Chart
- Ophthalmoscopy
- Slit-lamp Examination
Cataract Medical Management
-
Non-surgical Management
- Magnifying lens and increase light in room
- Doesn't prevent age-related cataracts
-
Surgical Management
- Considered when reduced vision interferes with normal activities
- Typically outpatient and takes less than 1 hour
- Extracapular extraction - Lens lifted and broken up by phasomulsification (ultrasonic vibrations)
- Intracapsular extraction - The lens and capsule are removed completely
- Lens implantation
Cataract Medications
-
Anticholinergics
- Cycloplegic (e.g., Catropine 1% ophthalmic solution)
- Prevents pupil constriction
- Relaxes eye muscles
Post-Cataract Surgery
- Best vision 4-6 weeks after surgery
- Itching and discomfort are normal
- Prevent infection
- Shield at bedtime
- Mydriasis - Pupil dilation
-
Ocular Injections
- Intraocular injections
- Medications used to stop abnormal blood vessels from leaking, growing
Retinal Detachment
- Any type of trauma to the head can cause a retinal detachment
- Most common signs:
- Hairnet or curtain-like half vision loss
- Floaters and cobweb-looking vision
- Flashes of light
Retinal Detachment Nursing Management
-
Key Points Education
- Avoid straining
- Avoid rubbing or scratching the eye
- Avoid eye straining activities
-
Report
- Sudden or new vision loss, pain, flashing light
Age- Related Macular Degeneration (AMD)
- Central loss of vision and blindness
- One of the top causes of vision loss in adults over the age of 60.
- Currently, there is no cure.
- Not a common part of aging.
Age-Related Macular Degeneration (AMD) Signs & Symptoms
- Blurry spot in the middle of vision
Age-Related Macular Degeneration (AMD) Types
-
Dry AMD
- Gradual blockage of capillaries leading to an ischemic macula
-
Causes
- Gradual blocking of and necrotic capillaries
- Rod and cone photoreceptor die
- Atrophic - Common cause of vision loss in older adults
-
Subtypes
- Serous
- Exudative
- Atropic
-
Wet AMD
- Thinning and growth of new blood vessels that leak
- Fluid and blood collect under the macula, resulting in scar formation and visual distortion
Age-Related Macular Degeneration (AMD) Patient Education
- Consume food rich in antioxidants, carotene, Vitamin E, and B12
Age-Related Macular Degeneration (AMD) Treatment
-
Intravitreal Anti-VEGF Treatment
- Ocular injection
- Most common ocular adverse event: Subconjunctival hemorrhage and vitreous hemorrhage
