Who is likely to get corneal ulcers?
Soft contact users
Corneal Ulcer
MEDICAL EMERGENCY
S&S: severe eye pain, foreign body sensation, tearing, and photophobia
Presentation:
whitish lesion on the cornea
Use penlight, slit lamp exam, and fluorescein dye test
Pseudomonas, Staphylococcus, or Streptococcus
Complications: Permanent vision impairment d/t scarring or perforation
Herpes Keratitis
S&S: Acute onset of severe eye pain, photophobia, tearing, and blurred vision in one eye
Dx: fluorescein dye
- fernlike lines in the corneal surface w/ fluorescein dye
Complications: permanently damages corneal epithelium, which may result in corneal blindness
Caused by: herpes simplex called herpes simplex keratitis
OR
herpes varicella zoster [shingles] called herpes zoster ophthalmicus
How does herpes keratitis differ from corneal abrasion?
HK: fernlike lines in the corneal surface.
Corneal abrasions: round or irregularly shaped
Herpes simplex keratitis
due to self-inoculation “cold sore”
Herpes zoster ophthalmicus
MEDICAL EMERGENCY
shingles of the trigeminal nerve
acute eruption of crusty rashes that follow the ophthalmic branch -> one side of forehead, eyelids, and tip of nose
Acute Angle-Closure Glaucoma
MEDICAL EMERGENCY
Sudden blockage of aqueous humor causes marked increase of the IOP, resulting in ischemia and permanent damage to the optic nerve
S&S Acute onset of severe eye pain accompanied by headache, nausea/vomiting, halos around lights, lacrimation, and decreased/blurred vision
PE: fixed and mid-dilated pupil(s) that is oval shaped. Slow reaction to light.
cloudy cornea
Cupping of the optic nerve
Multiple Sclerosis (Optic Neuritis)
S&S: Woman 20-30s
loss of visual acuity over hours to days
Color vision is affected & central scotoma (blind spot central vision)
Other neuro sx: aphasia, paresthesia, abnormal gait, spasticity
Fatigue that worsens through day
Refer to neuro
Multiple Sclerosis (Optic Neuritis) - Uhthoff phenomenon
Worsens in high temperatures
Orbital Cellulitis
MEDICAL EMERGENCY
S&S Acute onset of erythematous swollen eyelid with proptosis and pain
history of recent rhinosinusitis or URI
More likely in children
PE: Restricted EOMs w/ pain
Cause: acute bacterial infection of the orbital contents (fat and ocular muscles)
Retinal Detachment
MEDICAL EMERGENCY
S&S: Sudden onset of floaters (or increase in floaters) associated with “looking through the curtain” sensation with sudden flashes of light (photopsia)
Auricular Hematoma
Direct blunt trauma to the ear that can cause bleeding in the auricular cartilage
Drain ASAP
Complications: cauliflower ear
What professions are more at risk for an auricular hematoma
wrestlers, boxers, and mixed martial arts fighters
Acoustic neuroma (vestibular schwannoma)
50s to 60s
Unilateral hearing loss and tinnitus lasting 3 to 4 years
Unsteady walking with veering or tilting
Cause: tumor of acoustic nerve
Refer to neuro
Cholesteatoma
Unilateral heaving loss and discharge - purulent and foul smelling
On exam: TM perforation and White mass or intact with mass behind
H/o chronic or recurrent otitis media
Mass can erode into facial bones
Treat w/ abx or surgery
Refer to otolaryngologist
Battle Sign (Basilar Skull Fracture)
Indicates serious head injury -> ER
Parietal bone fracture w/ linear fracture most common
Cause: fall, assault, MVC, GSW
SS: raccoon eyes and bruising behind ear after trauma
PE: clear, golden serous discharge from ear or nose or hemotympanum (blue/ purple color to TM)
Avulsed tooth
DENTAL EMERGENCY
Need to reimplant tooth quickly
OK if baby tooth
If permanent tooth: don’t touch root, only touch crown
Rinse w/ saline, irrigate socket, reimplant tooth, bite on gauze
Can store tooth in milk, saline, or cheek if unable to reimplant
Peritonsillar Abscess
MEDICAL EMERGENCY
Sx: sore throat, odynophagia, trismus (jaw spasm), not potato voice. Malaise, fever
PE: unilateral swelling, uvula displaced
Diphtheria
REFER TO ED
Contact precaution
Sore throat, fever, and markedly swollen neck (“bull neck”)
Posterior pharynx, tonsils, uvula, and soft palate are coated with a gray to yellow pseudomembrane that is hard to displace
Very contagious
Virchow’s Node (Troisier’s Sign/Node)
enlarged and hard left-sided supraclavicular node(s)
can be malignancy (cancer of GI/GU)
Need biopsy
Normal Findings: Eyes
Fundi: veins larger/darker than arteries
Cones: color perception
Rods: low-light vision (night vision), peripheral vision.
Macula (and fovea): central vision and color vision. Fovea contains large numbers of cones. Diseases of the macula -> loss of central vision
Presbyopia
Age-related
decreased ability of the eye to accommodate and focus due to stiffening of the lenses;
usually starts at the age of 40 years;
near vision is affected with decreased ability to read small print
Blepharitis
Inflammation of the edges of the eyelids
oil glands at the base of the eyelashes become clogged.
eyelids are red, irritated, and itchy. Small scales like dandruff may be present.
Blepharitis tends to recur.
May be associated with dandruff, seborrheic dermatitis, or rosacea.
Normal Findings: Ears
Bones (ossicles) of the ear: Malleus, incus, and stapes. The stapes is the smallest bone in the body.
TM: translucent off-white to gray color with the “cone of light” intact. The pars tensa is located on the lower aspect and appears to bulge slightly. It is the area of the TM where the cone of light is visible.
Tympanogram: most objective measure to test for presence of fluid inside middle ear (results in a straight line vs. a peaked shape). Acute otitis media (AOM) and serous otitis media will show a straight line on testing
Pinna: Has a large amount of cartilage.
Tragus: A small cartilage flap of tissue on the front of the ear.
Cerumen: Ear wax; the color can range from yellow to dark brown.
