Sensory issues
§Hearing loss:
•congenital
•Recurrent
•infections
•cerumen impaction
§Visual loss:
•Cataracts
•SIB
•keratoconus
There are many etiologies for hearing loss in adults with DD.  It may be congenital, the result of infections or trauma, or transient such as is seen with cerumen impaction.  Assessment should be performed by ENT specialists and audiologists skilled at working with this population.  If augmentative devices are indicated, there may be a need for multiple trials as well as the use of desentization training in order to obtain optimal compliance and use.  For those individuals who have significant ceruminosis, consider the daily use of agents such as vegetable oil along with regular irrigation.
As with hearing loss, visual deficits are common and require careful evaluation and monitoring.  Sensory deficits are key in determining quality of life.  For example, they can contribute to injuries as well as cause worsening of behavior problems.  They also may be associated with painful conditions.  Glaucoma is especially difficult to recognize in its early treatable stages in individuals with severe DD.  For all these reasons, careful assessment and treatment is indicated.  Links to Arc webpages on guidelines for vision and hearing could go here
