Sensory Disorders

Simulates different corrective lenses

look through pipil to see the retina and presence of tumors and condition of the optic nerve

Beam through the cornea to view the eyes anterior structure to identify abnormal conjunctive cornea iris lens and anterior vitreous

Indirectly measures IOP Intraoccular pressure

visual of blood vessels in the retina dye is used

records minute electrical impulses given by the retina when light hits it

Ear exam using light and magnifying lens for the inner ear tympanicmembrane and points beyond the eardrum

pure tone test both conductive and sensory hearing deficits- bone conduction only tests conduction loss

Determines alteration in vestibular acoustic Nerve IV

• Client seated or supine

• client unsteady gait allowed to lie down until symptoms subside ( usually no more than an hour

• electrodes are placed near the clients eyes to
• -assess for alterations in vestibular system
• -caloric test is performed which eye movements are recorded on a graph
