Astigmatism abnormal curvature of the cornea, which causes blurry vision
Snellen Chart is used to test distance visual acuity Used for adults and school aged children it consists of letter in the English alphabet, and decreases in size

Contrast Sensitivity Testing the measurement of contrast sensitivity provides a screening test for earlier diagnosis and treatment of particular eye disease
Pelli-Robson Chart measures contrast sensitivity by defining the faintest contrast the patient can see
Vision Tester an instrument that offers simple screening in minutes

Eye Instillation medications are instilled to treat infections and to relieve inflammation, to dilate, or constrict the pupil, to anesthetize the eye for examination, and to stimulate circulation in the eye.
Eye Irrigation performed to flush the eye and may be ordered to relieve inflammation, remove foreign particles, cleanse and remove secretions due to infection, and flush out harmful substances such as chemicals

Conduction Loss occurs when sound waves cannot reach the middle ear due to impacted cerumen, obstruction of the ear canal, or swelling due to otitis media
Nerve Deafness occurs as a result of damage to the inner ear or the auditory nerve, which blocks the transmission of sound waves to the auditory centers of the brain
Degree of Hearing Loss Mild: may not hear soft speech Moderate: may affect language development, articulation, and interaction Moderate-Severe: difficulty with speech Severe: may affect voice quality Profound (deafness): both speech and language deteriorate
Audiometry instrument that measures hearing acuity at different frequencies
Tympanometry a procedure used to determine whether or not the middle ear is transmitting sound waves
Tympanmeter an electric device with an attached probe that is placed snugly in the patient's ear
Ear Instillation Liquids are instilled into the external auditory canal to treat infections, to relieve pain, and to soften impacted cerumen for easier removal
