Ophthalmology. General terms - conditions ● ● ● entropion/ectropion palpebrae -the turning inwards / outwards of the edge of the eyelid click horde-olum -medical name for a stye of the eye; hordeolum externum/internum click miosis - constriction of the pupil of the eye (both normal and pathol. ); mydriasis - dilation of the eye pupil click phot-o-phobia *phot- light *phobia -fear; abnormal sensitivity to or intolerance of light cor-ectopia - displacement of the eye's pupil from its normal, central position nystagmus - *gr. nystagm-nodding, drowsiness; involuntary eye movement; “dancing eye” ex-ophthalm-us /en-ophthalm-us - protrusion/ retrodisplacement of the eyeball from/within the orbit, caused by disease or injury. ophthalm-o-plegia - paralysis or weakness of the eye muscles epiphora = dacry-o-rrhoea - excessive flow of tears a-stigmat-ismus - type of refractive error caused by the irregularities in the shape of a person's cornea click cataracta - *gr. kataraktes- waterfall, broken water; a kind of portcullis - opacity/clouding of the lens of the eye or its capsule glauc-oma - * gr. -"cataract, opacity of the lens, " perhaps from glaukommatos "gray-eyed, " cataracts and glaucoma not distinguished until c. 1705. In the Hippocratic Aphorisms the term glaucoma was used to describe blindness coming on in advancing years associated with a glazed appearance of the pupil. Modern term glaucoma means a group of degenerative eye diseases characterized by damage to the optic nerve usually due to excessively high intraocular pressure - hypertensio intraocularis
Pathological conditions. ● ● ● glaucoma primarium / secundarium: diabeticum - Open-angle glaucoma, also called primary or chronic glaucoma/ Secondary glaucoma - may be caused by an eye injury, inflammation, certain drugs such as steroids and advanced cases of cataract or diabetes (sub) luxatio lentis traumatica (=ectopia lentis) - (partial) dislocation of eye lens due to trauma ablatio retinae (traumatica) - detachment of the retina cataracta congenita: hereditaria / acquisita: senilis - congenital form of cataract / acquired for of cataract: senile (in old age) etc. strabismus - strabism; squint eye - condition in which the eyes do not properly align with each other when looking at an object strabismus convergens = esotropia - the eyes are crossed ("cross eyed") strabismus divergens = exotropia the eyes diverge ("lazy eyed" or "wall eyed") click episcleritis syphilitica / tuberculosa inflammation of the layer on top of the sclera caused by syphilis / tuberculosis iridocyclitis acuta / subacuta acute / subacute inflammation of the iris and of the ciliary body degeneratio maculae luteae senilis senile type degeneration of the macula (yellow spot) ophthalmoplegia externa progressive external ophthalmoplegia; syndrome of diverse causes and is often accompanied by disorders of other tissues other than extraocular muscles
