Special senses terms Flashcards
Aqueous flare
An increase in protein content within the aqueous humor –> inc. light scatter
Cataract
opacification of the lens
Corneal edema
Injury to the corneal epithelium/endothelium/inflammation of the cornea -
“Blue eye” - Cloudy
Dyscoria
Abnormality in shape of the pupil
Keratic precipitates
Small clusters of macrophages/neutrophils adherent to corneal
endothelium - “speckles”
Keratoconjunctivitis Sica
Dry eye
Keratitis
Inflammation of the cornea
Keratomalacia
Melting ulcer
Neovascularization
small blood vessels forming a ring to injured area of cornea
Conjunctivitis
Inflammation of the conjunctiva
Chemosis
Severe conjunctival edema
Staphyloma
Iris ruptured through descmet’s membrane and healed into the cornea (causing
a corneal pigmentation)
Hypopyon
Accumulation of neutrophils and fibrin (exudate) that settles centrally within the
anterior chamber
Gondiodsygenesis
Malformation of filtration angle
Rubeosis Iridis
Reddening of the Iris
Posterior Synechia
Fibrous adhesions between Iris & lens
Anterior Synechia:
Fibrous adhesions between Iris & cornea
Bupthalmus
Enlargement of the eye
Blepharitis
Inflammation of the eyelid
Blepharospasm
Involuntary tight closure of eyelids
Phacolytic
Leakage of lens proteins from hyper mature cataract
Phacoclastic
Rupture of lens
Chalazion
Granulomatous inflammation directed against Meibomean gland
Stye
Common name for bacterial infection of hair follicle/Meibomean gland (S. Aureus
usually)
Phthisis bulbi
End stage eye –> Shrunken/atrophied/fibrotic eye
Miosis
excessive constriction of the pupil
Anterior uveitis
Inflammation of Iris & ciliary body (Iridis/cyclitis)
Posterior uveitis
Inflammation of Choroid (choroiditis)
Chorioretinitis
Inflammation of Choroid & retina
Endophthalmitis
Inflammation of Uvea, Retina, and Vitreous (all interior structures)
Panophthalmitis
Endophthalmitis + Cornea + Sclera (interior & outer covering)
Hyphema
Blood in anterior chamber
Cyclopia/Synopthalmos
Incomplete separation of the orbits during embryogenesis
Anophthalmia
RARE, No detectable development even of primary optic vehicle
Microphthalmia:
Miniature, disorganized globe in an orbit of relatively normal size
Ankyloblepharon:
normal fusion of eyelids
Distichia:
Ectopic row of cilia originating from the ducts of the Meibomean glands (usually
bilateral)
Ectropion
Outward gaping of eyelid margin, created by undue laxity of excessively long
eyelids
Entropion:
Inward rolling of eyelid margin because of inadequate overall length
Trichiasis
Misdirection of normal cilia so that they contact the cornea
Dermoid
portion of the cornea remains as skin with hair (failure of the fetal ectoderm to undergo complete “metaplasia”)
Coloboma
Notch like defects of optic disk, retina, and/or uvea –> defective closure of embryonic fissure (collie eye anomaly)
Scleral Ectasia
Prevention of proper local formation of choroid & sclera/ bulging of sclera
Ectopic cilia:
Abnormally placed cilia within laminar proprietary of conjunctiva
Aniridia
Rare, anomaly of extreme Iris Hypoplasia
Iris Bombe
Anterior bowing of the Iris - diffusely adhered to the lens
