acute infection
localized eyelid tenderness
may also not “pointing of mucopurulent material”

hard and nontender nodule in the eyelid
chalazoin
inching, burning, tearing, gritty, or foreign body sensation

unilateral
watery discharge, red and edematous eyelids
viral conjunctivitis
itching watery discharge and a Hx of allergies
Bilateral
allergic conjunctivitis
redness, forehin body sensation, discharge itching much less prominent

complain of having to wipe purulent exudate in the morning
Bacterial Conjunctivitis
Severe purulent discharge
hyperacute onset (within 12 to 24 hours)
Usually acquired through contact with infected genital secretions
Exam findings:
Tender palpable preauricular lymph node
Gonococcal Conjuctivitis
Red eye, foreign body sensation, usually asymptomatic unless there is associated chemosis
Red eye, foreign body sensation, usually asymptomatic unless there is associated chemosis
Conjuctival Hemorrhage
Caused by sunlight exposure, chronic inflammation and oxidative stress
Wing shaped fold of fibrovascular tissue arising from the interpalpebral conjunctiva and extending onto the cornea, usually nasal in location
Pterygium
Foreign body sensation, tearing, history of trauma; with or without a rust ring
Ocular Foreign Body
Severe pain, tearing, and photophobia
History of trauma to the eye, commonly involving a foreign object (fingernail, piece of paper, or contact lens)
Corneal Abrasion
Cornea reveals a round or irregular ulcer opacity or infiltrate
Severe ocular pain, photophobia, or blurred vision
Risk factor contact lens wearers
Corneal Ulcer
Trauma or recent ocular surgery are the most common risk factors
Blood or clot or both in the anterior chamber that may be black or red
Pain, sensitivity to light, blurred, clouded or blocked vision, history of blunt trauma
Hyphema
Pain, redness, photophobia, visual loss
hypopyon (WBC pool) and fibrin within the anterior chamber
Uveitis/Iritis
Risk factors:
Paranasal sinus infection, dental infection, orbital trauma
eyelid edema, erythema, warmth, tenderness, periorbital swelling, tooth pain
restricted extraocular motility with pain with eye movement
Orbital Cellulitis
Pain on attempted eye movement and local tenderness, eyelid edema, crepitus (particularly after nose blowing)
Step off deformity along frontal sinus
Restricted eye movement especially in upward or lateral gaze or both, subcutaneous or conjunctival emphysema, point tenderness,
Orbital Fracture
TRANSIENT
Vision returns to normal within 24 hours, usually within 1 hour
Acute Vision Loss
Flashes of light, floaters, a curtain or shadow moving over the field of vision, peripheral or central visual loss, or both
Risk factors
50 y/o
Nearsightedness
Cataracts
Retinal Detachment
Caused by use of a sunlamp without eye protection, exposure to a welding arc, or snow blindness
Numerous, microdots on the corneal surface after staining
Flash Burns
RISK FACTORS:
Job exposure
Improper PPE use
Excessive tearing, severe eye pain, photophobia, inability to open eyelids
Chemical Burn
Pain, decreased vision, loss of fluid from eye, Hx of trauma, fall, or sharp object entering globe
Low intraocular pressure
Penetrating Wound To eye
Photophobia, pain, eye redness, and decreased vision
History of oral or genital herpes infection
Dendritic keratitis branching
Eyelid may have typical herpetic vesicular eruptions
Palpable preauricular node
Herpetic Lesion of the eye
History of auricular trauma in subparicondural space
loss of normal cartilaginous
landmarks caused by trauma
Auricular Hematoma
