CONCLUSIONS

To evaluate the outcome of ophthalmic complications in children with otitis media. The records of children with ophthalmic complications arising from otitis media who presented to the British Columbia Children’s Hospital between August 2006 and March 2008 were reviewed retrospectively. Of 1,400 patients presenting to the emergency department for otitis media during the study period, 7 with ophthalmic complications were identified (age range, 1-11 years). All patients had abducens nerve palsy on presentation. Other notable ophthalmic complications included papilledema, Horner syndrome, and proptosis. Extracranial and intracranial complications included mastoiditis, petrositis, parapharyngeal abscess, hydrocephalus, epidural abscess, and cerebral venous thrombosis, including cavernous sinus thrombosis in 2. Of the 7 patients, 6 were treated with surgery, including myringotomy and tube placement (6 patients) and mastoidectomy (3 patients). All patients were initially anticoagulated and received intravenous antibiotics. Satisfactory final visual outcomes and stereopsis ranging from 40 to 100 seconds were achieved in all patients. Ophthalmic complications of otitis media in children are likely to include abducens palsy. All patients in our series required anticoagulation and intravenous antibiotics. Most required otolaryngologic surgery, but none required strabismus surgery, and all patients had satisfactory visual and ocular motility outcomes. ( J AAPOS 2011;15:272-275)

lthough the use of antibiotics has reduced complications of acute or chronic otitis media, it has become the most frequent indication for the prescription of antibiotics in children.1-5 Increased antibiotic use has increased the incidence of multiresistant organisms, and signs and symptoms of complications may be masked by previous antibiotic use.4-7 Because many cases of otitis media resolve spontaneously, in 2004, the American Academy of Pediatrics recommended an initial observation period of 2-3 days without antibiotic treatment in children with “uncomplicated” acute otitis media to reduce overuse of antibiotics.2,5,8 Although this approach should reduce antibiotic resistance, it could also lead to a resurgence of complications such as mastoiditis, meningitis, cranial nerve palsies, intracranial abscesses, cerebral venous sinus thrombosis, otitic hydrocephalus, and death.5,7,9-12 The purpose of this study is to identify the ophthalmic, Author affiliations: Department of Ophthalmology and Vision Sciences, British Columbia Children’s Hospital, University of British Columbia, Vancouver, BC, Canada Presented at the Canadian Ophthalmological Society Annual Meeting, Quebec City, Canada, June 26-29, 2010.

extracranial, and intracranial complications that may occur secondary to otitis media in this era of presumably reduced antibiotic use.

Methods The records of patients presenting to the Ophthalmology Department at the British Columbia Children’s Hospital (BCCH) with ophthalmic complications of otitis media from September 2006 to May 2008 were reviewed retrospectively. Ophthalmic complications included acquired esotropia, Gradenigo syndrome (otitis media, pain in the region innervated by the first and second divisions of the trigeminal nerve, and ipsilateral abducens nerve palsy), Horner syndrome, papilledema, and proptosis. Extracranial complications (mastoiditis, parapharyngeal abscess), and/or intracranial complications (cerebral venous sinus thrombosis, hydrocephalus, intracranial abscess) also were documented. This study received ethics approval from the University of British Columbia and British Columbia Children’s and Women’s Hospital Ethics committees.

Results Approximately 1,400 patients presented to the BCCH Emergency Department with otitis media during the study period; patients were referred to the ophthalmology clinic if ophthalmic complications of otitis media were noted. 7 patients (2 female) had ophthalmic complications of otitis media, and 6 of the 7 (86%) had a history of recurrent otitis media. Individual clinical cases are summarized in

e-Supplement 1 (available at jaapos.org); detailed case reports are available in e-Supplement 2 (available at jaapos. org). Two patients were being treated with oral antibiotics at the time of presentation. The microbiological profile in this series showed a variety of causative organisms, mostly comprising normal nasopharyngeal flora (Table 1). In our series, the ophthalmic complications of otitis media included abducens nerve palsy or Gradenigo syndrome (7 patients [100%]), papilledema (otitic hydrocephalus, 4 patients [57%]), proptosis (2 patients [29%]), and Horner syndrome (1 patient [14%]; Figures 1 and 2). All 7 patients developed esotropia secondary to abducens nerve palsy, for which 5 patients (71%) were prescribed parttime or full-time occlusion to prevent or manage amblyopia. Four patients with high intracranial pressure were treated with acetazolamide, with subsequent resolution of their papilledema. Cerebral venous sinus thrombosis occurred in 6 patients (86%), including 4 with chronic otitis media. Of the 7 patients, 2 (29%) also developed cavernous sinus thrombosis (Figure 3); orbital signs of lid swelling and proptosis were present in both. All patients were treated with broad-spectrum antibiotics (intravenous followed by oral) for a total of 4-6 weeks (e-Supplement 1). All patients were anticoagulated: 5 were treated with intravenous enoxaparin (low-molecularweight heparin), 1 with intravenous heparin, and 1 with aspirin. Six patients underwent myringotomy and tube insertion; 3, mastoidectomy; and 3, drainage of abscesses. A single patient was managed with antibiotics alone. Ophthalmic, otolaryngologic, and neurological complications resolved in all 7 patients, with normal visual acuity (Snellen 20/20) and stereopsis (4000 -10000 ) at a mean follow-up of 18 months (range, 2-36 months).

Discussion Prompt recognition and treatment of patients with ophthalmic complications of otitis media may prevent permanent neurologic and ophthalmic sequelae. A delay in presentation or misdiagnosis is associated with a greater rate of mortality.13,14 Our series suggests that a history of recurrent otitis media before presentation may be a risk factor for the development of complications.

All 7 patients in this series presented with the complete set of symptoms of Gradenigo syndrome. The complete triad of Gradenigo syndrome may not always be manifest, especially in patients partially treated with oral antibiotics, and the absence of one presenting symptom may lead to a delay in diagnosis.15-17 This was not a concern in our series, where all patients (even those already under treatment) presented with the complete triad. Cerebral venous sinus thrombosis is attributed to either direct spread of infection from the mastoid bone or from thrombophlebitis of small emissary veins of the mastoid that communicate with the lateral sinus.18,19 The lateral sinus and sigmoid sinus are at risk since they are

Volume 15 Number 3 / June 2011 Patients treated for otitis media are not routinely referred for ophthalmological consultation unless they develop obvious symptoms. It is possible that more patients developed milder ophthalmological complications of otitis media but were not referred because of relatively subtle findings. All patients in this series were treated with intravenous antibiotics after consultation with the infectious diseases specialist; antibiotics were continued for 4-6 weeks. No patient required thrombectomy, optic nerve decompression, ventricular shunt (lumboperitoneal or ventriculoperitoneal), or ligation of the internal jugular vein.13,16,20 All of our patients were treated with some form of anticoagulation. Shah and colleagues21 reported hemorrhagic complications in 2 children treated with enoxaparin for otogenic lateral sinus thrombosis. We therefore suggest that a hematologist be consulted before the initiation of anticoagulation therapy in such patients. No conclusive evidence links an increased incidence of otitis media complications with reduced or judicious use of antibiotics in the community, and although these cases continue to occur, our study was not designed to determine whether the incidence is changing. We suggest that clinicians maintain a high level of suspicion in patients with recurrent or persistent otologic disease, especially those with symptoms of headache, blurred vision, or diplopia.13,14 Clinicians should be particularly vigilant regarding the development of orbital symptoms, which in our series were associated with a high incidence of potentially lifethreatening cavernous sinus thrombosis.

An Eye on the Arts—The Arts on the Eye The woman seemed to have unlimited time for him. Gregorius had never had this feeling with any doctor…. He had expected her to measure the spare glasses, make the usual eye tests, and then send him to the optician with a prescription. Instead, she had him tell the history of his nearsightedness, stage after stage, concern after concern. When he finally handed her the glasses, she gave him a searching look. [. . .] The examination lasted more than an hour… Senhora Ec¸a studied the background of his eyes with the detail of somebody becoming familiar with a brand-new landscape. But what impressed Gregorius the most was that she repeated the test for visual acuity three times. In between were pauses when she had him walk back and forth and started a conversation about his profession. “How well one sees depends on so many things” she said smiling when she noted his amazement. —Pascal Mercier (from Night Train to Lisbon, Grove Press, New York, 2007)
