Inflammation of eyelid and eyeball lining: Causes include infectious and non-infectious etiologies: see Table Table 1Clinical Presentations That May Distinguish in Acute Conjunctivitis for distinguishing features.
Discharge/Cells Seen on Scraping
Pre-auricular Lymph Node
Clear to mucoid, eosinophils
Moderate to severe
Mild to severe
Still used in some countries as systemic therapy. Cases of bone marrow aplasia and death have been reported with prolonged/frequent use.
Twice-daily dosing. Preferred for chlamydial conjunctivitis over oral erythromycin. May cause fetal harm. Short courses do not appear to stain teeth in pts < 8 years old. Photosensitivity in 10-15%
Treats a wide range of bacterial eye infections, but may damage corneal epithelium with prolonged use. Use in treating specific gram negatives and S. aureus.
Eye drops: Big gun. Expensive. Alternative to ciprofloxacin. Would not use as the first line unless Pseudomonas suspected, as in contact lens wearers. May achieve superior microbial eradication rates vs. ofloxacin. No crystalline precipitate.
Not as well absorbed as other fluoroquinolones. Risk of crystalluria. Patients receiving norfloxacin should be well hydrated and should be instructed to drink fluids liberally. Otherwise similar to other quinolones.
Inconvenient four times a day alternative to doxycycline. May cause fetal harm. Stains teeth in pts < 8 years old. Photosensitivity.
Comment: Authors address the red-eye and provide helpful clinical distinguishing features to direct treatment. Of note, even bacterial conjunctivitis is usually self-limiting. Clinical data though is thin on most recommendations.
Comment: This guideline from the CDC handles conjunctivitis GC, CT infection including in neonatal populations.
Comment: A prospective, multicenter clinical trial demonstrated that AdenoPlus is a rapid, sensitive and specific in-office test for detecting adenoviral conjunctivitis when compared to traditional tests (PCR and CC-IFA).
Comment: Though usually self-limiting, review of 11 RCTs with 3673 patients finds some faster clinical improvement with the use of topical antibacterials.
Comment: A review of the use of topical azithromycin in the treatment of ocular infections including conjunctivitis. Summarizes the available RCTs.
Comment: A case report of HIV-positive patient treated for severe gonococcal conjunctivitis w/ daily ceftriaxone 1 g IM for 10 days.
Comment: Document outlines recommendations for control and environmental recommendations for adenovirus.
Comment: Acute hemorrhagic conjunctivitis (AHC) is an epidemic form of highly contagious conjunctivitis characterized by sudden onset of painful, swollen, red eyes, w/ conjunctival hemorrhage and excessive tearing. The report summarizes outbreak in Puerto Rico; 490K persons were affected; school-aged children and those living in crowded urban areas were at highest risk. To control outbreaks, prevention methods (e.g., frequent hand washing and avoidance of sharing towels and bedding) should be targeted to groups at highest risk.
Comment: A prospective, randomized-controlled, double-masked, multicenter study comparing the efficacy and safety of 0.5% levofloxacin ophthalmic solution with 0.3% ofloxacin ophthalmic solution for the treatment of bacterial conjunctivitis. Although clinical cure rates in the 0.5% levofloxacin and 0.3% ofloxacin treatment groups were similar, a 5-day treatment regimen with 0.5% levofloxacin achieved microbial eradication rates that were statistically superior to those attained with 0.3% ofloxacin. There was no difference in the incidence of treatment-related adverse events.
Comment: Patients with adenoviral conjunctivitis need to dispose of unclean contact lenses as adenovirus survives chemical and hydrogen peroxide disinfection.
Comment: The in vitro antimicrobial susceptibilities of ocular isolates to levofloxacin, ofloxacin, and ciprofloxacin were determined. Levofloxacin demonstrated superior in vitro activity against human bacterial conjunctival isolates compared with either ofloxacin or ciprofloxacin (levofloxacin > ofloxacin > ciprofloxacin).
Comment: The predominant organism from the corneal scrapings of 11 contact lens wearers with bacterial keratitis was Pseudomonas aeruginosa.
Comment: In patients with allergic conjunctivitis, eye rubbing causes increased ocular itching, chemosis, and hyperemia.
Comment: Contact lens wearers are at risk for the development of bacterial keratitis. The bacteria most commonly isolated in this study were Serratia spp and Pseudomonas aeruginosa.
Comment: 12/26 patients with epidemic keratoconjunctivitis had positive adenovirus hand cultures.
Comment: A multicenter, double-masked, randomized trial was conducted comparing 0.3% ofloxacin and 0.3% tobramycin for topical treatment of external ocular infection. Ofloxacin was found as effective, safe, and comfortable as tobramycin.
Comment: In a double-masked, randomized-controlled study the effectiveness and safety of 0.3% ofloxacin solution were compared with those of 0.3% gentamicin ophthalmic solution in treating external bacterial ocular infections. The two treatments were found to be equally effective.
Comment: In two multicentered, randomized, prospective clinical studies, ciprofloxacin 0.3% ophthalmic solution was compared to placebo and to tobramycin 0.3% respectively. In both trials cipro was approximately 94% effective. Although cipro was significantly more effective than placebo, there was no difference in efficacy between ciprofloxacin and tobramycin.
Comment: This small study of 12 patients remains the only study examing conjunctival GC. A single 1g IM injection of ceftriaxone in these 12 patients, all responded.
Comment: Johns Hopkins study examined epidemiology of acute conjunctivitis in an inner city population. Out of 45 patients, viral conjunctivitis was diagnosed in 36%, bacterial in 40%, while 24% of cases remained undiagnosed.
Comment: 158 patients, 21 years of age or less, presenting with culture-positive (Haemophilus influenzae or Streptococcus pneumoniae) conjunctivitis were treated with trimethoprim-polymyxin B,gentamicin sulfate or sodium sulfacetamide ophthalmic solution for 10 days. Clinical response at 3 to 6 days after start of therapy was similar for all test agents. Clinical response at 2 to 7 days after completion of therapy was also similar, as was bacteriologic response.
Comment: Review of 21 cases of gonococcal conjunctivitis between 1972 and 1986. Keratitis, anterior chamber inflammation, periocular edema and tenderness, gaze restriction and preauricular adenopathy were common findings. All patients were hospitalized and received parenteral antibiotics. Only 2/21 patients had a poor outcome.
Comment: A double-masked randomized study was conducted at four centers to compare the efficacy and safety of tobramycin and gentamicin ophthalmic ointment in the treatment of superficial external eye disease. The results indicate that tobramycin is safe, effective and comparable to gentamicin. There was a trend towards better efficacy, safety and fewer adverse reactions in the tobramycin-treated group, but the differences were not statistically significant.
Comment: Trimethoprim-Polymyxin B is safe and well tolerated for the treatment of bacterial conjunctivitis in children. It is effective against both gram-positive and gram-negative organisms including S pneumoniae and H influenzae, the most prevalent pathogens in pediatric patients.
Comment: 84% of responders rated ketorolac as good to excellent in relieving their overall symptoms of ocular allergy and 86% felt that the drug produced good to excellent relief of their ocular itching within minutes to 1 hour of administration.
