THE RED AND PAINFUL EYE

ANATOMY
PHYSICAL EXAM – VVEEPP + TOOLS
In the context of a red and painful eye:
Visual Acuity (Visual Fields) External examination Extraocular movements Pupils Pressure (normal < 20 mmHg)
Fundoscopy and Slit lamp
SLIT LAMP
ROSEN’S APPROACH TO THE RED EYE
Do you think anything got into your eye? What could it be?
Caustic Injury? Proptosis/swelling? Severe pain, foreign body sensation, or
limbal injection? Focal redness of bulbar conjunctiva? Purulent discharge? Itching? Topical med, makeup?
CASE #1
APPROACH TO CASE #1
Do you think anything got into your eye? Yes
What could it be? DO SOMETHING!!!
Caustic Injury? Most likely
CAUSTIC INJURY
CAUSTIC INJURIES
BAAAAD Irrigation, irrigation irrigation (> 30 min) until
pH of tear is neutral If solid caustic agent present (look carefully),
remove with dry cotton swab before irrigating. Alkali worst than acids Opthalmology consultation, topical antibiotic,
cycloplegics, cross fingers
TRIVIA
CASE #2
CASE #2
APPROACH TO CASE #2
Do you think anything got into your eye?
Caustic Injury? Proptosis/swelling? Severe pain, foreign body sensation, or
limbal injection? Focal redness of bulbar conjunctiva?
Yes
SUBCONJUNCTIVAL HEMORRHAGE
Well demarcated at the limbus
Flat, smooth, brightred, limited tobulbar conjunctiva
Often occurs as a result of trauma orvalsalva
Not painful
DC home, cold compress
TRIVIA
CASE #3
CASE #3
Pain ++, sudden onset Was in the basement Now, sensitive to light Nausea and vomitting Can’t see well out of affected eye
APPROACH TO CASE #3
Do you think anything got into your eye?
Caustic Injury? Proptosis/swelling? Severe pain, foreign body sensation, or
limbal injection? Yes
ACUTE ANGLE-CLOSURE GLAUCOMA
Pupillary block of aqueous humor
Precipitated by pupillary dilation Darkness Emotional upset Anticholinergics Sympathomimetic
s Rapid rise in IOP Leads to damage
to the optic nerve up to blindness
ACUTE ANGLE CLOSE GLAUCOMA
Treatment Visual acuity reduced to hand movements
Topical Beta blocker (Timolol) Sympathomimetic (Pilocarpine) Alpha 2 agonist (Apraclonidine) Steroid (Prednisolone)
IV Carbonic anhydrase inhibitor (Acetazolamide) Osmotic agent (Mannitol)
Visual acuity just blurry, IOP < 30 mmHg Mannitol and pilocarpine not required.
In both cases, consult Ophtalmology (surgery)
TRIVIA
CASE #4
CASE #4
Pain Photophobia Slightly blurry
vision
APPROACH TO CASE #4
Do you think anything got into your eye?
Caustic Injury? Proptosis/swelling? Severe pain, foreign body sensation, or
limbal injection? Yes
HYPHEMA
Spontaneously resolve Complications include:
Rebleed Corneal blood staining IOP
Classic management Antifibrinolytics Raise head, bed rest Cycloplegics Steroids
…. No effect
GHARAIBEH A, ET AL.: MEDICAL INTERVENTIONS FOR TRAUMATIC HYPHEMA.
We found no evidence to show an effect on visual acuity by any of the interventions evaluated in this review.
[Patients] who receive aminocaproic acid or tranexamic acid are less likely to experience secondary hemorrhaging. However, hyphema in patients on aminocaproic acid take longer to clear.
MANAGEMENT
Rule out globe rupture (US) If:
Small hyphema (less than 50%) No vision loss No IOP No hemoglobinopathy (sickle cell)
Conservative management
If not, patient would benefit from ophtalmological follow up and IOP management
PATIENT COMES BACK!!
Complaining of increasing pain Painful and reduced ocular movements Decreased visual acuity
Notice he looks familiar
RETROBULBAR HEMATOMA
Injury to orbital vessels Hemorrhage in a confined space Increased pressure Compromise of vessels and optic nerve
Needs urgent decompression
RETROBULBAR HEMATOMA
Medical Topical beta blocker (timolol) IV carbonic anhydrase inhibitor (acetazolamide) IV osmotic agent (mannitol)
Surgical Lateral cathotomy Needle aspiration Surgical decompression of hematoma
TRIVIA
CASE 5
36M, comes with eye pain Sudden onset Sawing through a piece of metal No eye protection
APPROACH TO CASE #5
Do you think anything got into your eye? Yes
Do you know what it could be? A piece of metal
SLIT LAMP EXAM
• Patient is immediately relieved with topical analgesia
SEIDEL TEST
To rule in a corneal penetration Place a fluorescein strip over the abrasion Quick dilution of the concentrated fluorescein
by leaking aqueous humor
IMAGING
Ultrasound more sensitive, but CT delineates damage better
KERATITIS + PERFORATION
Pain Foreign body sensation Tearing Injected conjunctiva Blepharospasm History often supportive Don’t forget to look under the eyelids!
Can also occur with: Insects UV light (arc welding)
MANAGEMENT – FOREIGN BODY
No penetration Removal of FB
Irrigation Cotton tip Do no use syringe, use small IV catheter
Rust rings from ferrous FB best removed the following day
Topical antibiotics, no need for patch Opthalmology if symptoms do not improve
If penetration suspected Consult opthalmology to determine damage
extent NO MRI!!
