(outward deviation of eye)
• Abnormal corneal light reflex or cover test
• Misaligned eye

• Sensorineural losses- involve interference of the
transmission along the nerve pathways
• Caused by congenital defects or secondary to
acquired conditions (infection, ototoxic med, exposure to
constant noise)
• Central auditory imperception – involves all other hearing
losses (aphasia, agnosia [inability to interpret sounds])
