|
Red flags for adult with acute red eye
|
Blurred vision, loss of vision, photophobia, eye pain, epiphoria, ciliary injection, hyphema, foreign body
|
|
|
Hyphema
|
a hemorrhage in the anterior eye chamber, usually due to trauma
|
|
|
Subconjunctival hemorrhage
|
superficial bleeding between conjunctiva and sclera, usually due to minor trauma or idiopathic
|
|
|
Ciliary injection
|
engorgement of BVs that originate from the anterior uvea (iris, choroid, ciliary body) indicating injury, inflammation, or infection of the anterior eye
aka ciliary hyperemia or ciliary flush |
|
|
Conjunctival injection
|
engorgement of conjunctival blood vessels.
BVs move along with the conjunctiva as it slides over the eyeball aka conjunctival hyperemia |
|
|
S/S of acute iritis
|
Symptoms- photophobia, blurred vision, eye pain, epiphoria
Signs- ciliary injection, miosis, KPs |
|
|
S/S of acute glaucoma
|
Symptoms- intense peri-orbital eye pain, HA, blurred vision, nausea and vomiting, photophobia
Signs- ciliary injection, mydriasis, increased IOP, clouding of cornea, shallow anterior chamber |
|
|
Ddx. to sudden intense HA
|
Acute glaucoma, subarachnoidal hemorrhage, temporal arteritis, acute meningitis
|
|
|
Complications to acute iritis
|
Synechiae, iris bombe, corneal calcium deposition, cataract, glaucoma, phthisis bulbi
|
|
|
Acute angle closure glaucoma complications
|
Blindness, iris atrophy, anterior lens opacity (Glaukomflecken)
|
|
|
Acute glaucoma
|
aka angle-closure or narrow-angle glaucoma
develops quickly with vision loss caused by shallow anterior chamber adn occlusion of the canal of schlemm with accumulation of anterior aqueous humor --> increased IOP |
|
|
Chronic glaucoma
|
aka open-angle glaucoma
develops slowly, with no initial S/S in anterior eye. slow increase in IOP leading to atrophy of optic nerve and cupping of optic disc ultimately leads to blindness |
|
|
Normal IOP
|
less than or equal to 22mmHg
sudden change may be alarmingly dangerous |
|
|
Dangerous conditions, requiring immediate referral
|
Gonococcal, chlamydial, pseudomonas, neonatal conjunctivitis
Herpes keratitis Acute glaucoma, iritis, iridocyclitis, anterior uveitis Acute and chronic posterior uveitis |
