Anatomy of the Eye
This part of the eye contains muscles that control pupil dilation and constriction.
What is the iris?
This chart is used to measure visual acuity, with a normal reading being 20/20.
What is the Snellen eye chart?
This disorder occurs when the retina separates from the underlying tissue, leading to flashes of light and vision loss.
What is retinal detachment?
This part of the ear collects and transmits sound waves to the tympanic membrane.
What is the external auditory canal?
This infection of the middle ear is common in children and causes ear pain, fever, and hearing loss.
What is otitis media?
This structure is the transparent outer layer of the eye that bends light to help focus vision.
What is the cornea?
This handheld device allows healthcare providers to examine the retina and optic nerve.
What is an ophthalmoscope?
This infection, commonly known as “pink eye,” can be caused by bacteria, viruses, or allergens.
What is conjunctivitis?
These three small bones in the middle ear transmit sound vibrations from the tympanic membrane to the oval window.
What are the malleus, incus, and stapes?
This type of hearing loss occurs due to damage to the inner ear or auditory nerve.
What is sensorineural hearing loss?
This gel-like substance fills the posterior cavity of the eye and helps maintain its shape.
What is vitreous humor?
This assessment checks extraocular muscle function by having the patient follow an object in six directions.
What are the six cardinal fields of gaze?
This common age-related condition results in the lens becoming cloudy and impairing vision.
What is a cataract?
This structure of the inner ear contains the organ of Corti, which transforms sound vibrations into electrical impulses.
What is the cochlea?
This common age-related hearing loss results in difficulty understanding speech.
What is presbycusis?
These photoreceptors in the retina allow for color vision.
What are cones?
This test is used to assess color vision by showing numbers embedded in a pattern of colored dots.
What is the Ishihara Color Test?
Increased intraocular pressure can lead to this group of diseases that cause optic nerve damage.
What is glaucoma?
This cranial nerve transmits auditory and balance signals from the ear to the brain.
What is the vestibulocochlear nerve (CN VIII)?
This disorder is caused by excess fluid and pressure in the inner ear, leading to vertigo and hearing problems.
What is Ménière’s disease?
This nerve transmits visual information from the retina to the brain.
What is the optic nerve (CN II)?
This test helps detect blind spots and peripheral vision loss.
What is perimetry (confrontation visual field testing)?
This autoimmune-related eye disorder results in dry, irritated eyes due to decreased tear production.
What is keratoconjunctivitis sicca (dry eye syndrome)?
These structures in the inner ear help maintain balance by detecting head movements.
What are the semicircular canals and vestibule?
This condition occurs when free-floating debris in the semicircular canal causes sudden episodes of vertigo.
What is benign paroxysmal positional vertigo (BPPV)?
