Pediatric orbital cellulitis is most often caused by ethmoid sinusitis. We present a description of 4 atypical cases of orbital cellulitis without sinusitis. ⋯ Orbital cellulitis in children poses diagnostic and therapeutic difficulties due to the many possible etiologies. Aside from sinusitis, the most important etiologies to pursue are lacrimal system infections and tumors. When confronted with a non-specific clinical presentation, thorough etiologic work-up is essential, in view of the potential life-threatening, functional and social implications.

Preoperative anxiety is often expressed by patients requiring filtration surgery for their glaucoma. So far, there has been no scale for screening this group of patients for preoperative anxiety. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a self-evaluation questionnaire which has been used in specialties other than ophthalmology and which makes it possible to identify the adult patients with a high level of preoperative anxiety over an upcoming surgical procedure. The purpose of this study is to estimate the preoperative anxiety in glaucoma patients requiring filtration surgery. ⋯ The French version of the APAIS is a quick scale, easily completed, that can be recommended for evaluating anxiety and patients' need for information prior to filtering surgery. It is usually easier for the surgeon to find ways to reduce the patient's anxiety if a relationship of trust has been established between the two.

Phthiriasis palpebrarum is an ectoparasitosis in which Phthirus pubis infest the eyelashes. It is rare and it can easily be misdiagnosed as blepharitis. The purpose of this study is to describe seven cases of phthiriasis palpebrarum so as to discuss its mode of infestation, diagnosis and treatment. ⋯ In conclusion, phthiriasis palpebrarum can be easily diagnosed by close examination of the eyelashes and eyelid margins at the slit lamp and can be managed mechanically. Parasitological examination of the eyelashes can confirm the diagnosis.

Optic neuropathy is a severe and well-known complication of ethambutol treatment. If not detected early, it may lead to profound and irreversible vision loss. ⋯ Bitemporal hemianopia on visual field testing is very suggestive of a chiasmal lesion, which is generally due to a compressive, or more rarely inflammatory, lesion in the sellar region. Toxic chiasmal lesions are rare, but in the absence of any tumoral lesion in the sellar area, a detailed history must be obtained in order to rule out drug toxicity, so as to prevent irreversible visual loss.

Case Reports
[Sixth, seventh and tenth cranial nerve palsies associated with pseudotumor cerebri in a 13-year-old boy].
We describe the case of a 13-year-old boy who presented to the emergency department with an acute onset paresis of the left abducens, facial and vagus nerves. Bilateral papilledema was seen on fundoscopy. Blood tests and brain magnetic resonance imaging and angiography showed no abnormalities. ⋯ Treatment with acetazolamide was initiated, resulting in progressive improvement with no sequelae and no clinical recurrence over an 8-month follow-up period. PTC in children can present with a wide spectrum of neurological signs, especially cranial nerve palsies which are most likely related to a pressure-dependent stretching mechanism. In 2007, distinctive diagnostic criteria for pediatric PTC were established, including the presence of any cranial nerve palsy in the absence of an identifiable etiology.
