SENSORY DISORDER
 Sensory disorder is a condition in which the brain
has trouble receiving and responding to
information that comes in through the senses.
 The condition used to be called sensory
integration dysfunction.
 Some people with sensory processing disorder are
oversensitive to things in their environment.
Common sounds may be painful or overwhelming.
The light touch of a shirt may chafe the skin.
DEFINITION OF SENSORY DISORDER
Others with sensory processing disorder may:
 Be uncoordinated
 Bump into things
 Be unable to tell where their limbs are in space
 Be hard to engage in conversation or play
 Sensory processing problems are usually identified
in children. But they can also affect adults. Sensory
processing problems are commonly seen in
developmental disorders like autism.
 Sensory processing disorder is not recognized as a
stand-alone disorder. But many experts think that
should change.
 Blindness is strictly defined as the state of
being totally sightless in both eyes. A
completely blind individual is unable to see
at all.
 The word blindness, however, is commonly
used as a relative term to signify visual
impairment, or low vision, meaning that
even with eyeglasses, contact lenses,
medicine or surgery, a person does not see
well. Vision impairment can range from
mild to severe.
BLINDNESS
 Colour blindness is the inability to perceive differences
in various shades of colours, particularly green and
red, that others can distinguish. It is most often
inherited (genetic) and affects about 8% of males and
under 1% of women. People who are colour blind
usually have normal vision otherwise and can function
well visually. This is actually not true blindness.
 Night blindness is a difficulty in seeing under situations
of decreased illumination. It can be genetic or
acquired. The majority of people who have night vision
difficulties function well under normal lighting
conditions; this is not a state of sightlessness.
The different types of blindness?
 Snow blindness is loss of vision after exposure of
the eyes to large amounts of ultraviolet light. Snow
blindness is usually temporary and is due to
swelling of cells of the corneal surface. Even in the
most severe of cases of snow blindness, the
individual is still able to see shapes and
movement.
Cont..
 Common causes of blindness
include diabetes, macular degeneration, traumatic
injuries, infections, glaucoma, and inability to obtain
any glasses.
 Less common causes of blindness include vitamin
A deficiency, retinopathy of prematurity, vascular
disease involving the retina or optic
nerve including stroke, ocular inflammatory
disease, retinitis pigmentation, primary or secondary
malignancies of the eye, congenital abnormalities,
hereditary diseases of the eye, and chemical poisoning
from toxic agents such as methanol.
 Temporary blindness differs in causes from permanent
blindness.
What causes blindness?
 Discomfort in the eyes, awareness of the eyes, foreign
body sensation, and pain in the eyes or discharge from
the eyes may be present or absent, depending on the
underlying cause of the blindness.
 A blind person may have no visible signs of any
abnormalities when sitting in a chair and resting.
 However, when blindness is a result of infection of the
cornea (the dome in front of the eye), the normally
transparent cornea may become white, making it
difficult to view the coloured part of the eye.
SYMPTOMS AND SIGNS OF BLINDNESS
 Treatment of visual impairment or
blindness but it is depends on the cause.
 Nutritional causes of blindness can be
addressed by dietary changes.
 The treatment for people who are blind
from cataract is undergo cataract
surgery that will restore their sight.
 Inflammatory and infectious causes of
blindness can be treated with medication in
the form of drops or pills.
