-Caused by a clogged eyelid gland 2 infxn to staph Aureus
Treatment for a Hordeolum?
Warm compresses, topical abx, I&D if refractory
Chalazion
Non-painful, noni infectious, chronic stye
-Granulomatous rxn arising from clogged internal glands
Tx for Chalzion?
Trial of warm compressses but usually need excision by Opthalmology
Blepharitis
Diffuse eyelid inflammation, like dandruff of the eye.
-2 to seborrheic dermatitis, Strep, Staph, glandular dysfuntion
Tx for Blepharitis?
Gentl lid scrubs with baby shampoor, topical abx
Viral Conjunctivitis
Unilateral or bilateral conjunctival injection, watery discharge, +/- preauricular adenopathy
-Usu caused by Adenovirus
Tx of Viral conjuctivitis?
Eye rinses, cool compresses, no school**
Usu tx with abx in the real world
Bacterial Conjunctivitis?
Copious purluents drainage, eyes glued shut in am
-Usu staph, strep but can by chlamydia or gonnococus
TX: Topical abx, pseudomonas coveragle for contact wearers **Can be an STD
Clogged tear duct with bacterial super-infection?
Dacrocystitis Tx with warm compresses and top Abx, may need I&D
Periorbital edema, erythema, Infxn of tissues surronding the eye—Pain with extraocular eye movements***
Orbital Cellulitis
Hit in the eye with Limited extraocular movements, Pt can’t look up
Blowout fracture—Needs Urgent Opth surgical repair
Exam for Foreign Bodies of eye
Topical anesthetic, fluorescein stain, evert eyeleids
Metallic foreign bodies can leave a rust ring….
Painful tearing red eye with persistent foreign body sensation.
Corneal abrasion.
Fluorescein stain, look for Ice Rink sign. No patching, no topical anesthetic prescriptions
Deep erosion in cornea on Fluorescein stain?
Corneal Ulcer, Pseudomonas in contact lens wearers
Acute blurry vision, bisual field cut, flasher/floaters, +/- trauma. *Like a curtain being drawn over the eye**
Retinal Detachment: Opth. Emergency
Hyphema?
Blood in anterior chamber, “8 ball” hyphema covers iris. Usually traumatic. Can cause increase IOP.
Gradual onset of blurry vision caused by opacificatoin of the lens
Cataract—Ref to Optham, lens removal/implant
Leading cause of irreversible central visin loss, usually age related?
Macular Degeneratoin—Drusen Deposits lead to degenarative changes of the retina.

Ectropion
Eyellid turning in
Entropion
Srabismus
Crossed eyes
Pinguecula?
Raised fleshy conjunctival mass from chronic sun, wind and dust expusrus. Not tx necessary but if bothersome can be removed

Leading cause of blindness in adults?
Diabetic Retinopathy
Rapid, involuntary, rhythmic eye movements (horizontal, vertical, or rotational.
Seen with normal horizontal head movement. many causes
Palilledema?
Swelling of optic disc indicative of increased intracranial pressure, usu bil. Increased IOP
Glaucoma?
Increased IOP >20 mmhg. Impaired aqueous humor drainage from the anterior chamber through the Canals of Schlemm.
Chronic, Open Angle Glaucoma
Grad onset symptoms (pain, blurry vision, or asymptomatic) Usu > 40 Outpt. referral for tx
Acute, Angle Closure Glaucoma
Sudden onset, severe pain, vision loss, red eye, fixed mid-dilated pupil with steamy cornea and elevated IOP. Emergency, needs STAT Opthal. IV Acetazolamide, BB eye drops. Osmotic diuresis
Sudden unilateral painless vision loss 2 to embolus, thrombus, or vasculitis? Box car arteriolar narrowing, “Cherry Red Spot” Retinal pallor.
Central Retinal artery occlusion. Medical Opth emergency** Poor prognosisi
