1 Orbital Trauma Grant S Lipman MD Wilderness Medicine Fellow Clinical Instructor, Division of Emergency Medicine Stanford University School of Medicine

2 Case Presentation 12 hrs s/p blepharoplasty – c/c: bleeding eyelid. “I’ll only see a plastic surgeon.” PE- venous blood from incision VSS, eye grossly normal VA – 20/20 bilaterally, PERL Plastics: “What kind of insurance does he have? Cash? I’ll be down.” 3- 4 hours later- repeat PE: VSS, right eye dilates to light.

3 Orbital Architecture

4 Approach to eye examination ULTIMATE GOAL Systematic Exam VA – vital signs EOM/Sensation Slit lamp exam Fundus Referral

5 Corneal Abrasions – Presentation Symptoms Signs

6 Corneal Abrasions VA test Remove contacts Slit-lamp exam

7 Corneal Abrasions

8

9 Corneal Abrasions - Management To patch or not to patch, that is the question. Flynn et al: J. Family Practice Le Sage N et al:Ann of EM Contact lens wearer Non-contact lens wearer Topical anesthetics Ophthalmology consult? Follow- up: 48 hrs

10 Subconjunctival Hemorrhages Definition Symptoms Signs Complete exam Treatment

11 Iritis- Presentation Definition Symptoms Photophobia Eye pain Signs Limbus injection Miosis Mydriasis VA

12 Anterior Chamber Reaction

13 Hypopyon

14 Iritis – Management Complete Examination. Cycloplegic NSAIDS Sunglasses No antibiotics Topical steroids? Follow-Up

15 Hyphema- Presentation Definition Symptoms Grading 0 RBC’s I <1/3 II 1/3 – 1/2 III > 1/2 IV eight ball

16 Hyphema- Management Ophthalmic consult Pupillary play/Eye Patch Reverse Trendelenburg Anesthesia /Anti-emetic IOP control > 30 mmHg (>24 mmHg in HbSS) Admission HbSS Anti-coagulated > Grade I Decreasing VA ED evaluation > 1 day after initial injury. Complications Re-bleed Post-traumatic glaucoma

17 Lens subluxation and dislocation Definition Disposition Subluxed Dislocated Post-traumatic Cataract

18 Retinal Detachment /Vitreous Hemorrhage Definition Symptoms Photopsia Image distortion Painless Floaters Floaters with flashing light Defects in VA

19 Vitreous Hemorrhage VA/Red reflex/RAPD Fundoscopy Ophthalmology consult Disposition

20 Retinal Detachment RAPD/VA Fundoscopy Shafer Sign Ophthalmology consult Disposition

21 Retrobulbar Hemorrhage - Presentation Definition Symptoms Critical signs Proptosis Visual acuity Marcus-Gunn pupil Red desaturation

22 Retrobulbar Hemorrhage- Management “TIME IS RETINA” Progressive Lateral canthotomy CT scan of orbit Disposition

23 Blowout Fracture- Presentation Definition Symptoms Pain Double vision Numbness to cheek tenderness Critical signs Restricted EOM Subcutaneous emphysema Globe displacement Globe trauma 32%

24 Blowout Fracture - Etiology Theories Waterhouse 1999 Buckling Hydraulic Fracture site Inferior wall Medial wall Superior rim CNS injury CSF leak Intracranial - bleed

25 Blowout Fracture- X-ray Screening Teardrop sign

26 Blowout Fracture- CT Clinical indications Depressed eye Nerve anesthesia EOM entrapment Orbital roof Coronal and axial cuts

27 Blowout fracture- Management Consults Nasal Decongestants Antibiotics Evidence? Sneezing/Blowing Nose Disposition With entrapment Without entrapment Associated injuries

28 Ruptured Globe – Presentation Incidence % Symptoms Predictive signs 1) VA showing light perception or worse. 2) Abnormal deep/shallow anterior chamber. 3) Opacity preventing view of fundus. 4) IOP of 5 or less.

29 Ruptured Globe - Management Diagnosis Suspected – STOP Examination Do NOT put pressure on globe RSI Br. J of Anesth 1999 Antibiotics Tetanus Antiemetic CT scan Prepare for surgery.

30 Take home points Systematic approach to eye exam Visual acuity = vital signs of the eye. Goal – protect the globe Complete ocular examination Corneal Abrasions: antibiotics, do not patch Subconjunctival hemorrhages – painless Iritis – cycloplegics and sunglasses Hyphema- Ophthalmology, patch, IOP. Lens – subluxed vs. dislocated Posterior segment – floaters/ flashing lights = Ophtho Retrobulbar hemorrhage – loss of VA, pain, proptosis. time is retina Blowout fracture – Waters view, CT for entrapment. Globe rupture – Ophthalmology, patch.

31 Case Presentation Patient to OR for a stat lateral canthotomy. S/p operation, VA is 200/45 in right eye. Retrobulbar hemorrhage is a 1 in 15,000 side effect of blepharoplasty.
