Term | Definition |
---|---|
Acous/o | hearing |
Adnexa | conjoined, subordinate, or associated anatomic parts. |
Ambly/o | dull, dim |
Amblyopia | dimness of sight especially in one eye without apparent change in the eye structures. |
Amentropia | an abnormal refractive eye condition (as myopia, hyperopia, or astigmatis) in which images fail to focus upon the retina. |
Anacusis | total absence of hearing |
Aque/o | water |
Astigmatism | a defect of an optical system (as in lens) causing rays from a point to fail to meet in a focal point resulting in a blurred and imperfect image. |
Audi/o | hearing |
Audiomentry | the testing and measurement of hearing acuity for variations in sound intensity and pitch and for tonal purity. |
Audit/o | hearing |
Aur/o | ear |
Blast/o | immature, embryonic |
Biephar/o | eyelid |
Cataract | a clouding of the lens of the eye or its surrounding transparent membrane that obstructs the passage of light. |
Chalazion | a small circumscribed tumor of the eyelid formed by retention of secretions of the meibomian gland and sometimes accompanied by inflammation. |
Cochlear Implant | electrical prosthetic device that enables individuals with sensorineural hearing loss to recognize some sounds and that consists of an external microphone an speech processor that receive and convert sound waves into electrical signals |
Conjunctvitis | inflammation of the conjunctiva that is typically marked by pinkness or redness of the sclera and by itching, burning, irritation, discharge, or excessive tearing of the eye and is typically caused by pathogenic microorganisms, allergens, or irritants. |
Cusis | suffix for hearing. |
Diplopia | a disorder of vision in which two images of a single object are seen (as from unequal action of the eye muscles). |
Ectropion | an abnormal turning out of a part (as in eyelid) |
Emmetr/o | correct, proper |
Emmetropia | the normal refractive condition of the eye in which with accommodation relaxed parallel rays of light are all brought accurately to a focus upon the retina. |
Enculeation | surgical removal of eyeball |
Esotropia | strabismus in which the eye turns inward toward the nose. |
Exotropia | strabismus in which the eye turns outward away from the nose. |
Glaucoma | a disease of the eye marked by increased pressure within they eyeball that can result in damage to the optic disk and gradual loss of vision. |
Hermianopia | blindness in one half of the visual field of one or both eyes. |
Hyperopia | a condition in which visual images come to a focus behind the retina of the eye and vision is better for distant than for near objects. |
Iridectomy | the surgical removal of part of the iris of the eye. |
Iritis | inflammation of the iris of the eye. |
Keratitis | inflammation of the cornea of the eye characterized by burning or smarting, blurring of vision, and sensitiveness to light and caused by infectious or noninfectious agents. |

Labyrinthectomy | surgical removal of the labyrinth of the ear. |
Mastoidectomy | surgical removal of the mastoid cells or of the mastoid process of the temporal bone. |
Media | substances regarded as the means of transmission of a force or effect. |
Mydr/i | widening |
Mydriasis | excessive or prolonged dilation of the pupil of the eye. |
Myopia | condition in which the visual images come to a focus in front of the retina of the eye because of defects in the refractive media of the eye or of abnormal length of the eyeball resulting especially in defective vision of distant objects. |
Myringotomy | incision of the tympanic membrane. |
Nyctal/o | night |
Nyctalopia | night blindness. |
Ophthalmoscopy | examination of the eye with an ophthalmoscope. |

Otopyorrhea | discharge pus form the ear. |
Otorrhea | a discharge from the external ear. |
Otoscierosis | growth of spongy bone in the inner ear where it gradually obstructs the oval window or round window or both and causes progresively increasing deafness. |
Otoscope | instrument to view inside the ear canal. |
Papilledema | swelling and protrusion of the blind spot of the eye caused by edema. |
Photophobia | an abnormal fear of light. |
Presbycusis | a lessening of hearing acuteness resulting from degenerative changes in the ear that occur especially in old age. |
Presbyopia | a visual condition which becomes apparent especially in middle age and in which loss of elasticity of the lens of the eye causes defective accommodation and inability to focus sharply for near vision. |
Ptosis | a drooping of the upper eyelid (as from paralysis of the oculomotor nerve). |
Radial Keratotomy | a surgical operation on the cornea for the correction of myopia that involves flattening the cornea by making a series of incisions in a radial pattern resembling the spokes of a wheel. |

Sclerotomy | to cut into the sclera. |
Stapedectomy | surgical removal of prosthetic replacement of part or all of the stapes to relieve deafness. |
