The Eye Flashcards
(14 cards)
How do cataracts affect the function of the eye?
- Cataracts are clouding of lens
- Poor night vision
- Halos around lights
- Colour activity may lessen
- Light is poorly focused
- Increased cloudiness
State two effects of cataracts on vision
- May have double vision
- May have small spots or patterns where vision is less clear
- The glare from bright lights may be dazzling or uncomfortable to look at
- Everything may have a yellow or brown tinge
- Colours may fade or become less clear
Measures that places of work can take to promote the safety and independence of people with visual impairments
- No trip hazards
- Guide dogs allowed on premises
- Alarms auditory
- Important signs well displayed
- Adapted computer screens
Describe a function for each of the following
- The humours
- The iris
The Humours: Supports eye/ feeds eye/ distributes nutrients/ help refract light/ protects eye and retina from shock
The iris: regulates the amount of light entering the eye, controls light passing through the pupil
Impact of age related macular degeneration on daily life
- May not be able to work
- Not recognising faces
- Unable to drive
- Difficulty dressing
- Difficulty reading or other activities involving close vision
Analyse suitable strategies or support that could allow an individual with AMD to lead an independent lifestyle
-Use of brighter lighting
-Decorate rooms in colours to aid vision
-Highlighting necessary objects with colour
-Use of magnifiers
-Use of sound alert for warnings as
opposed to flashing lights
-Advice and help from social services and
occupational therapists for financial
assistance and household/daily
adaptations
-Use of audio books and instructions
-Learning Braille
-White sticks/probes
-In extreme cases use of a Guide Dog
-Appropriate medical interventions, for
example, medication, stem cell, laser
treatment.
-Use of support groups.
Identify one effect AMD will have on vision
Macula destroyed resulting in loss of central vision, inability to
read
Identify the layer of the eye affected by AMD
Retina
Monitoring of Cataracts
- Eye Tests
- Visual Activity exam
- Regular check up
Identify which part of the eye is responsible for producing liquid to moisten the eye
Tear Glands
Identify which part of the eye is responsible for forming a thin protective layer covering the front and inside of eye lids
Conjunctiva
Identify which part of the eye is responsible for first part of the eye to focus light
Cornea
Identify which part of the eye is the coloured part that controls the light in the eye
Iris
Identify which part of the eye is responsible for the lining at the back of the eye that contains cells sensitive to light
Retina
