Chapter 11 Flashcards
Amblyopia
Dimness of vision or partial loss of sight without detectable disease
Ametropia
Any error of refraction in which images do not focus properly on the retina
Anisocoria
Pupils are uneven in size
Astigmatism
The eye does not focus properly because of uneven curvatures of the cornea
Barotrauma
Pressure related ear condition
Blepharoptosis
Drooping of eyelid due to paralysis
Cataract
The loss of transparency of the lens of the eye
Chalazion
A nodule or cyst usually on the upper eyelid caused by an obstruction of a sebaceous gland
Cochlear implant
An electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve
Conjunctivitis
Inflammation of the conjunctiva usually caused by an infection/allergy
Dacryoadenitis
Inflammation of the lacrimal gland that can be caused by a bacterial viral and fungal infection
Dilopia
The perception of two images of a single object
Ectropion
The eve version of the eyelid
Emmetropia
Normal relationship between the reflective power of the eye and shape
Esotropia
Strabismus characterized by an inward deviation of 1/both eyes
Entropion
The inversion of the edge of an eyelid
Eustachitis
Inflammation of eustachian tube
Exotropia
Strabismus characterized by the outward deviation of one Eye relative to the other
Florescein
Application of fluorescent dye to the surface of the eye
Glaucoma
Group of diseases characterized by increased intraocular pressure that causes damage to the optic nerve and retinal fibers
Hemianopia
Blindness in one half of the visual field
Hordeolum
Pus-filled lesion on the eyelid resulting from infection in the sebaceous gland
Hyperopia
A vision defect in which light rays focus to be on the retina farsightedness
Infectious Myringitis
Inflammation that causes painful blisters in the eardrum
Iridectomy
Surgical removal of portions of the iris used to treat angle glaucoma
Iritis
Inflammation of uvea primarily affecting structures in front of Eye
Keratitis
Inflammation of cornea
Labyrinthectomy
Surgical removal of all/part of labyrinth – relieve stress vertigo
Laser tubercularplasty
Treat open angle glaucoma by openings in the trabecular meshwork to allow fluid to drain
Mastoidectomy
Surgical removal of mastoid cells – used to prepare for cochlear implant
Myopia
A defect in which light rays focus in front of the retina
Myringotomy
Small surgical incision in the eardrum to relieve pressure from excess pus or fluid or to create opening for ear tubes
Nyctalopia
Condition where an individual with normal daytime vision has difficulty seeing at night
Nystagmus
Involuntary, constant, rhythmic movement of the eyeball
Ophthalmoscopy
Examination of the fundus with ophthalmoscope – Dilation required
Optometrist
Treats and corrects vision impairment
Otitis media
Inflammation of middle ear
Otomycosis
Swimmers ear – fungal infection of external auditory canal
Otopyorrhea
Flow of pus from ear
Otorrhagia
Bleeding from ear
Otosclerosis
anklyosis of bones in middle ear, resulting in conductive hearing loss
Papilledema
Inflammation of optic nerve at the point of entrance into the eyes through the optic disk
Periorbital edema
Swelling of the tissues surrounding the eye
Presbycusis
Gradual hearing loss as body ages
Prebyopia
Condition of, changes in the eye
Pterygium
Growth that develops on the conjunctiva or mucous membrane
Radial keratotomy
Procedure used to treat myopia
Retinopexy
Reattach the detached retina detachment
Scleritis
Inflammation of the sclera of the eye
Stapedectomy
Anklyosis of bones of middle ear, resulting in conductive hearing loss
Strabismus
When eyes point in different directions or not aligned correctly because Eye muscles are unable to focus together
Tarsorrhaphy
Partial/complete surgical suturing of eyelids paralyzed
Tinnitus
Condition of ringing, buzzing, or roaring sound in one or both ears
Tonometry
Measure of intraocular pressure
Tympanometry
Use of air pressure in ear canal to test for disorders of middle ear
Tympanostomy
Surgical incision to restore Eye function
Vertigo
Sense of whirling dizziness, loss of balance, can cause nausea and vomiting
Vitrectomy
Removal of vitreous fluid and it’s replacement with a clear solution
Xerophthalmia
Dry eyes, including conjunctiva
Adnexa
Supporting structures of the eye
