Challenges of Eye Complaints

• Similar complaints (redness, pain, visual changes) may represent benign or vision threatening etiologies

• Rapid diagnosis and therapy can be vision saving

• Visual loss is devastating for the patient and physician

• Most residents are uncomfortable with eye complaints

Page 3: Eye

General Approach to Eye Complaints

• History- onset, trauma, history of same, discharge,

perceived vision, field defects, associated symptoms (halos, headaches), allergies

Physical Exam- Visual acuity, general inspection (pupils, obvious

foreign bodies, discharge, lid eversion), fundoscopy, visual fields, slit lamp (cornea, anterior chamber)

Page 4: Eye

Everting the eyelid

Page 5: Eye

Common Eye Lid Disorders

• Blepharitis- Acute or chronic eyelid

inflammation, causing crusting of the lids (infectious vs. allergic)

• Stye- Acute staph infection of an

eyelid follicle• Chalazion – meibomian gland

cyst (painless, non infectious) often confused with a stye

Many causes of the “Red Eye”

• A middle-aged man comes in with complaints of a painful red eye.

• He said the pain developed after coming out of a movie theater. “It feels like a migraine” (headache, nausea, vomiting) “The lights have halos around them”

• What’s the probable diagnosis?

Page 8: Eye

Acute Angle Closure Glaucoma

• What are findings on physical exam?– Visual acuity: – Conjunctiva:– Cornea:– Pupil:– Anterior

chamber:

Page 9: Eye

What is the anterior chamber

Page 10: Eye

Shallow anterior chamber

• How can you demonstrate a shallow anterior chamber?

• OBLIQUE FLASHLIHGHT TEST

Page 11: Eye

Acute Angle Closure Glaucoma

• What is a normal intra-ocular pressure (IOP)?

• How do you measure the IOP?

Page 12: Eye

Another “Red Eye”• Patient presents whose right

eye is red, painful and very sensitive to light.

• When you shine the penlight in her left eye, it causes her pain in the right (affected) eye.

• What diagnosis does it suggest?

Page 13: Eye

Iritis

• What might you find on examination of the anterior chamber by slit lamp?– Headlights in the

fog– Dust in a sunbeam

Cell and Flare

My baby’s got pink eye

• A patient in a big hurry comes in to see you. She is disheveled and scantily dressed. She says, “my baby’s got the pink eye

• She has a 5 day old infant with a bilateral eyelid swelling and a thick purulent discharge from both eyes.

Page 16: Eye

My baby’s got the pink eye

• Should you just give her the antibiotic drops?

• What’s the diagnosis?• Where did the baby get

the infection?• Does mom need to be

treated?

Page 17: Eye

Eye pain and FB sensation

• A middle-aged man complains of a foreign body sensation in the left eye

• Fluoroscein staining of the cornea reveals the following lesions. Diagnosis?

• Should we initiate therapy with steroids?

• Complications?• Stain everyone!

Page 18: Eye

Red painful eye in a contact lens wearer

• A patient who wears contact lenses presents with a painful red eye

• Diagnosis? • Treatment?

Page 19: Eye

Eye pain in a contact lens wearer• Never patch a contact lens wearer

• Advisable to cover for Pseudomonas in a contact lens wearer

• No benefit to pressure patching in terms of rate of healing or pain reduction

Page 20: Eye

Painful eye. Diagnosis?

Page 21: Eye

Another red eye

• A three-year old child presents with erythema and swelling around the left eye.

• The Pediatric resident says, “It’s periorbital cellulitis; start the kid on antibiotics and send him home.”

• Are you comfortable with that?

Page 22: Eye

Sudden painless visual loss

• The nurse has an elderly man with a history of CAD and TIA's who says he can’t see anything out of his left eye. The loss of vision was sudden and painless.

• What diagnosis does this presentation suggest?

Page 23: Eye

Central retinal artery occlusion (CRAO)

• How long before this visual loss becomes permanent?

• Physical exam findings?– Visual acuity/field:– Pupillary exam:– Retina:

Page 24: Eye

• Doctor, I see flashes of light and a curtain has dropped over my right lower visual field…

• Diagnosis?

Page 25: Eye

• Doctor, I can’t see well out of my right eye. It’s hazy and there are floaters…

• Diagnosis?

Page 26: Eye

Traumatic Conditionsof the Eye

Page 27: Eye

Poked in the eye!

• A young boy presents to the ER after having been poked in the eye by another student.

• He is being seen by a resident who is just about to measure the child’s intra-ocular pressure when you yell “STOP!!!!!!”

• Why are you so uptight?• Now what should you do?

Page 28: Eye

• Emergency Ophthalmology Consultation

• Protect the eye

• Avoid eye manipulation

• NPO

• Prophylactic antibiotics

• Update Tetanus

• Antiemetics

• Analgesics, Sedation

• Avoid Succinylcholine?

FB sensation

• A young male presents to the ER with foreign body sensation to this left eye.

• He was pounding a nail and felt something get into his eye.

• You examine patient and find that other than some photophobia, his exam is normal.

• You are about to discharge him when the attending says, hold on just a minute. What could you have possibly missed?

• How do you make the diagnosis?

Page 30: Eye

Positive Seidel’s

• You carefully examine the patient and place fluorescein in his eye. You see the fluorescein streaming.

• What is this called? • What does it

signify?

Page 31: Eye

Drain cleaner in the eye• A patient comes to the ER

having gotten some drain cleaner in her eye and it's causing her a lot of pain.

• The triage nurse tells her the wait to be seen is 1 hour and the patient becomes irate and starts to leave.

• You happen to overhear this conversation

• What should you do? Why?• Treatment?• How long?

Page 32: Eye

Baseball versus eye

• A young male presents to the ER after having been hit in the eye with a baseball. He says, "I keep seeing double when I look up".

• Diagnosis?• Pathophysiology?• Treatment?

Page 33: Eye

BLOWOUT FRACTURE

Symptoms:• Diplopia• Epistaxis

Signs:

• Crepitus/tenderness over orbital rim or maxilla

• Periorbital subQ emphysema • Limitation of EOM• Enophthalmos • Anesthesia of the ipsilateral

cheek and upper lip - WHY?• Periorbital ecchymoses/swelling

Pathophysiology

Page 34: Eye

Blunt Trauma

• The patient may also have a hyphema

• Make sure to look with a slit lamp

• Some may be microscopic- Blurred vision- Risk of re-bleed, glaucoma

Page 35: Eye

Blunt Trauma

• They may also have a subconjunctival hemmorhage or lens dislocation.

Page 36: Eye

Eyelid laceration• A young child

presents to the emergency department with a small laceration of her left upper eyelid.

• What's that protruding from her laceration?

• What does it signify?

Page 37: Eye

“Eyelids don’t have fat”

• Orbital fat usually protrudes through septal lacerations

• Fat in the lid laceration confirms the diagnosis

• High incidence of globe penetration and intraocular foreign bodies

• High risk for orbital cellulitis
