Differential Diagnosis
• Ophthalmia neonatorum (neonatal
conjunctivitis)
• Neonatal dacryocystitis
• Periorbital cellulitis
Differential Diagnosis
Ophthalmia neonatorum: in this patient
Pros
• Age of onset
• Clinical symptoms
• Most common cause in newborn
Cons
• No history of maternal infection or
vaginal discharge

Dec; 6:807-13
Differential Diagnosis
Neonatal Dacryocystitis
• onset 2-4 wk
• Tenderness & swelling in medial
canthal region
• Epiphora most prominent
• ± purulent D/C from puncta,
cellulitis, conjunctivitis,
In this patient
• Epiphora was not eminent
• No tenderness & swelling in medial canthal region
Lang, Gerhard K., Ophthalmology: a short textbook, 2000 Georg Thieme Verlag,
Differential Diagnosis
Periorbital cellulitis
• Local spread (preceded
with URI)
• Acute eyelid erythema
and edema
• Pain, epiphora
• ± fever, conjunctivitis,, leukocytosis
In this patient
• Mild eyelid edema
• No Hx of URI, hordeolum, bug bite, trauma
• Discharge more prominent than swelling

• Possible causes of illness (trauma, bug bites)
Approaching pediatric conjunctivitis
Physical examination
• eyelid eversion: hyperemia, follicles, papillae,
membranes
• Characters and amount of discharge (purulent,
mucoid, watery, bloody)
• Detailed eye exam if possible (EOM, VA,
pupillary reaction, proptosis)

sinusitis, meningitis, arthritis)
Ophthalmia neonatorum
Ophthalmia neonatorum
• Neonatal conjunctivitis – during the first mo
• Aseptic – chemical: silver nitrate
• Septic – bacteria, chlamydia, virus
• Septic neonatal conjunctivitis
• Neisseria gonorrhoeae (GC) – most serious
• Chlamydia trachomatis – most common
• Non-gonococcal, non-chlamydial
• Acquire during passing through the birth canal
Incidence
• One of the most common eye disease
in neonate
• Incidence ranging from 1.6-12.0%

 neutrophils, lymphocytes,
plasma cells
• Gram stain

infection
• Giemsa stain
• Culture

Investigation for
Chlamydial infection
• Conjunctival scraping for chlamydia
• Giemsa stains from lower conjunctiva
• intracytoplasmic inclusion bodies
• Do not collect from ocular discharge alone
• Culture
• Non-culture method
• Direct immunofluorescent antibody assay
• Nucleic acid amplification tests (PCR)

Management
1. If there are systemic symptoms, admit the
patient for specific treatments and further
investigation
2. Laboratory investigations include discharge
G/S, cultures
3. IV or IM third-generation cephalosporin should
be given before laboratory results
4. Topical ATB is not necessary
5. Consult ophthalmologist
Specific treatment
1. Gonorrhea conjunctivitis (non-disseminated)
• Admit and separate patient from other babies
• Ceftriaxone 25-50 mg/kg/day IM single dose not to
exceed 125 mg.
• Irrigated with NSS frequently until discharges disappear
• Treat parents
2. Chlamydia conjunctivitis
• Erythromycin oral 50 mg/kg/day qid for 14 days
• 0.5% erythromycin ointment tid/qid for 3 wks
(unnecessary but may be adjunctive)
• Irrigated with NSS frequently until discharge disappear
• Treat parents
Red Book: 2006 Report of the Committee on Infectious Diseases. 27th ed.
Prophylaxis
• Baby that born from Gonorrhea-infected mother
• Ceftriaxone 25-50 mg/kg/day (max 125 mg)
IM single dose stat or aqueous pen-G 100,000 U
IV single dose
• The American Academy of Pediatrics and the U.S.
Centers for Disease Control(CDC)
1% silver nitrate solution
0.5% erythromycin ointment
1% tetracycline ointment

Progression
16/4/50 (Day 1)
• Admit (consult ophthalmologist: r/o orbital cellulitis)
• Observe clinical signs: sepsis
• RE: mild lid swelling, not tensed, erythema;
conjunctival injection with chemosis; purulent bloody
discharge wih pseudomembrane, full EOM
Progression
16/4/50 (cont.)
• Investigation
• G/S of discharge: numerous PMN, no organism
• Giemsa staining of conjunctival scraping: pending
• Discharge culture for GC, bacteria, Chlamydia
trachomatis: pending
• CBC: Hb 12.7 g/dL Hct 38.1% WBC 11640/mm3
N30.5% L 49.7% M16.2% E3.4% B0.2% plt
343000/mm3
Progression
16/4/50 (cont.)
• Imp: Ophthalmia neonatorum,
suspected C. trachomatis conjunctivitis
• Start ATB covering GC and Chlamydia
• Ceftriaxone 50 mg/kg/day iv over 30 min, single dose
• Erythromycin Syr 50 mg/kg/day for 14 days
• Topical ATB : erythromycin ed. (Tobrex ed. instead)
• Evaluate and treat mother  OPD Gynae
Progression
17/4/50 (Day 2)
S: active child, afebrile
O: RE: eyelid swelling, soft;
conjunctival injection with
chemosis; purulent bloody
discharge; normal cornea
A: not worse
P: continue treatment
18/4/50 (Day 3)
• Giemsa stain (16/4/50): not appropriate specimen
• Repeated conjunctival scaping for Giemsa
• Zymar (Gatifloxacin) ed to RE q 2 hr (12.5 MKdose)
Progression
19/4/50 (Day 4)
• Afebrile
• RE: eyelid not swelling, conjunctiva-mildly injected,
small amount of discharge, clear cornea
• Plan F/U OPD eye 1 week, with Giemsa stain result
Take home message
• NB with conjunctivitis are at risk of systemic infection
• Hx of mother (ANC, STD, perinatal Hx) and child
• Complete PE
• Treat for GC if it cannot be ruled out and admit if there is
evidence of systemic infection.
• Presumptive treatment is based on the clinical picture,
G/S and Giemsa
• Systemic ATB, not just ATB eye drop, is recommended.
(Chlamydia, GC, HSV)
• Evaluate and treat the parents.
