*Todd Margolis, M.D.,PhD, Prof of Ophthalmology and Director F. I. Proctor Foundation, UCSF (Now Chair of Ophthalmology at Washington University in St. Louis)Brian Schwartz, M.D., Associate Professor of Medicine, Division of Infectious Diseases
Case
• 31 yo male with a h/o HIV with a CD4 319, not on ARV therapy, who c/o blurry vision for 3 months
• Had seen an ophthalmologist 1 month into symptoms and was told that he had ?cataracts
• Over the ensuing 2 months he had decreasing vision and finally presented to urgent care with right eye pain, redness and photophobia
Case
• Should he be referred to an ophthalmologist?
• What is the diagnosis?

Sub-conjunctival hemorrhage
SCLERITIS
Episcleritis/Scleritis
• Episcleritis
– Acute onset/minimal pain
– Self‐limited
– Non‐tender
– No work‐up needed
– No Rx needed
• Scleritis
• insidious onset/dull achy pain
• Chronic
• Tender
• Work‐up needed (Rhem/ID)
• Rx needed
Viral Conjunctivitis
• Adenovirus until proven otherwise– ~ 50% were seen recently by eye care
provider
• No history, no vesicles = no herpes
• Tender node may take 3-5 days to develop

Management of viral conjunctivitis
• Supportive care (cold AT, vasoconstrictors)
• Antibiotic coverage unwarranted
• Corticosteroids prolong viral shedding
ChlamydiaConjunctivits Chlamydia Conjunctivitis
• Less common than viral conjunctivitis
• Not an acute conjunctivitis– Chronic, indolent inclusion conjunctivitis
• Diagnosis suspected when patients fail to respond to topical antibiotic therapy
• Can confirm diagnosis by DFA, culture or PCR
• Therapy is doxycycline or azithromycin

Management of Bacterial Conjunctivitis
• Prime suspects:– S. aureus, Strep. pneumonia, H.
influenza***• First line drugs:
– Sulfacetamide– Polymixin/trimethoprim
• 72 hour rule
Hyperacute Bacterial Conjunctivits
1/27/2016
6
Hyperacute Bacterial Conjunctivits
• Due to Neisseria gonorrhoeae
• Characterized by:– Acute onset
– Copious purulent discharge
– Chemosis and eye lid swelling
– Rapid progression
• Emergency that requires systemic antibiotics
Management of Bacterial Conjunctivitis
Drugs to avoid– Ointments: poor compliance
– Erythromycin: very high rates of resistance
• H. influenza 94%, S. epi. 70%, S. aureus 45%, Strep. pneumo 8%
– Aminoglycosides: coverage & toxicity
– Fluoroquinolones: expense. Save for resistant cases.
Clinical Diagnosis of Bacterial Conjunctivitis
(Rietveld RP et al, BMJ 2004;329:206)
• Dutch study of primary care physicians
• 184 adults (not contact lens wearers) presenting with a red eye and discharge
• All patients cultured– 57 with + bacterial cultures
– 120 negative cultures

Clinical Diagnosis of Bacterial Conjunctivitis
(Rietveld RP et al, BMJ 2004;329:206)
• 3 questions:– Are eyes glued shut in the morning?
– Do eyes itch?
– Previous history of conjunctivitis?

Allergic Conjunctivitis
• History of allergies, rubbing or itching
• Typical periocular skin changes
• Stringy, mucoid discharge
• Eosinophils on giemsa stain
1/27/2016
8
Management of Allergic Conjunctivitis
• Cold compresses• Cold artificial tears• Topical antihistamines/vasoconstrictors – Visine A, Naphcon
A, Opcon A– OTC– Use < 2 weeks– Can cause rebound hyperemia
• Antihistamine + mast cell stabilizer – Patanol/Lastacaft• REFER if severe symptoms persist after 3 weeks of
antihistamine/mast cell stabilizer therapy• Topical corticosteroids/pulse steroids--leave to
ophthalmologist
Contact Lens Related Problems
• Dirty lens• Torn lens• Lens overwear• Corneal abrasion• Drug toxicity/allergies/abuse• Infections
Contact Lens Users Are Contact Lens Abusers
• 41 million contact lens users > 18 yrs of age
• ≈ 1/3 of wearers reported a red or painful eye requiring a doctor’s visit
• When surveyed, what % of users reported lens hygiene behavior associated with increased risk of infection?

Management of Bacterial Corneal Ulcer
• Culture
• Topical fluoroquinolones (ciprofloxacin, ofloxacin, levo-, nor-,gati-,moxi-)
• Fortified topical antibiotics (cefazolin, vancomycin, tobramycin)

Review of ocular syphilis
• Ocular syphilis may occur in secondary or tertiary syphilis
• Uveitis is the most common manifestation, but can also have a keratitis or scleritis.
• Bilateral eye involvement is seen in about 50% of patients
• All patient with presumed ocular syphilis should have a lumbar puncture to exclude concomitiant meningitis.
• Ocular syphilis is often, but not always, accompanied by syphilitic meningitis.

• He also received Benzathine PCN 2.4 million units x1 at the end of his 2 week therapy
• At last follow up his vision was improved

Management of Blepharitis
• Anterior Blepharitis– Lid hygiene– Topical antibiotics (erythromycin, bacitracin)
• Posterior Blepharitis– Lid hygiene– Warm compresses/massage– Topical antibiotics (as above)– Doxycycline (50 mg po bid)– “Z-Pak”

Management of HSV Eye Disease
• Acyclovir (400mg TID)– Famciclovir 500 mg TID– Valacyclovir 1 gm BID
• If there is corneal involvement —> REFER– Debridement– Topical steroids

Management of VZV Eye Disease
• Start antivirals early! • Acyclovir (800mg 5X day), Valacyclovir (1 gm TID)
& Famciclovir (500mg TID) are equally efficacious in preventing vision threatening ocular complications
• Institute aggressive pain management • Refer to Ophthalmologist even if the eye does not
look involved – Neurotrophic cornea precautions
