141. Epidural Hemorrhage (Treatment)

epidural formation has been reported. If a rapid size increase is noted and/or the patient develops anisocoria or a neurological deficit, then surgery is indicated. Middle meningeal artery embolization has been described in the early stages of EDH, especially when angiographic dye extravasation has been observed (see Future and Controversies). When treating patients with spontaneous EDH, the underlying primary disease process must be addressed in addition to the fundamental principles discussed above

neurologic deficits, such as aphasia, anisocoria, and memory deficits, may also be seen. Benign paroxysmal torticollis of infancy is characterized by episodes of a head tilt, and benign paroxysmal vertigo of childhood is characterized by recurrent episodes of vertigo and ataxia. The torticollis typically occurs during the first year, whereas the vertigo occurs in young children (usually aged 2-3 years). Cyclic vomiting and recurrent abdominal pain frequently are considered migraine variants. Before

of injured cells. Phenytoin reduces the incidence of early posttraumatic seizures, although it does not affect late-onset seizures or the development of a persistent seizure disorder. In a small case series, ED skull trephination before transfer of patients with CT-proven epidural hematoma (EDH) and anisocoria resulted in uniformly good outcomes without complications.

Adult Horner's syndrome: a combined clinical, pharmacological, and imaging algorithm The diagnosis of Horner's syndrome (HS) can be difficult, as patients rarely present with the classic triad of ptosis, miosis, and anhydrosis. Frequently, there are no associated symptoms to help determine or localise the underlying pathology. The onset of anisocoria may also be uncertain, with many cases referred after incidental discovery on routine optometric assessment. Although the textbooks discuss

150. Entrance Pupil Size Predicts Retinal Illumination in Darkly Pigmented Eyes But Not Lightly Pigmented Eyes. Full Text available with Trip Pro

Entrance Pupil Size Predicts Retinal Illumination in Darkly Pigmented Eyes But Not Lightly Pigmented Eyes. We determined the effect of entrance pupil size on retinal illumination. The influence of unilateral miosis on the magnitude of the pupil light reflex was studied to ascertain how a clinically significant anisocoria influences the relative afferent pupil defect (RAPD).Miosis was induced by topical 1% pilocarpine in the right eye of 14 healthy subjects with normal eyes. The interocular (...) difference in retinal illumination was assessed by computerized pupillometry from the stimulus response curve of the right and left eyes. The main outcome measure was the RAPD, determined by computerized pupillography, at baseline and after pilocarpine-induced anisocoria.Induced anisocoria produced a significant change in RAPD from baseline (mean = 1.60 dB in the miotic eye, P = 0.007). However, anisocoria correlated with RAPD only in subjects with darkly pigmented irides (Pearson correlation coefficient

Intracranial hydatid cyst is a rare cause of midbrain herniation: A case report and literature review Hydatid disease is a parasitic infection affecting the brain in about 2% of the cases. Brain involvement is most commonly observed in children. Here, we report a 13-year-old male patient who presented with headache, nausea, and vomiting. Before cranial computed tomography (CT) was performed, the patient had generalized epileptic seizures. He was disoriented, and had anisocoria with dilatation

153. Results of a community vision-screening program using the Spot photoscreener. (Abstract)

Association for Pediatric Ophthalmology and Strabismus guidelines. Data were stratified by age group and analyzed for percentage of children referred for hyperopia, myopia, astigmatism, anisometropia, anisocoria, and ocular misalignment. Vision screening records were compared with comprehensive eye examination records from an optometrist or ophthalmologist to determine positive predictive value.Vision screening examinations were performed on 8,317 subjects from September 2011 through May 2012. The mean (...) age of the 7,814 subjects (3953 males) meeting inclusion criteria was 44.4 months. The Spot referred 2,393 (30.6%). Of the screened population, the suspected reason for referral was astigmatism in 1,863 (23.8%), ocular misalignment in 879 (11.3%), anisometropia in 90 (1.2%), myopia in 82 (1.1%), hyperopia in 63 (0.8%), and anisocoria in 16 (0.2%). Comprehensive examination reports, including a cycloplegic refraction, were available for 300 referred children (12.5%). The reason for referral

Central serous chorioretinopathy after blunt trauma The authors report a case of a 46-year-old Hispanic male with central serous chorioretinopathy (CSC) following blunt trauma to the left eye. The patient presented with a complaint of throbbing headache and blurry vision in left eye. The patient was diagnosed with diabetes mellitus 1 year previous to the event. On examination, uncorrected visual acuity was 20/20 OD, 20/200 OS. No anisocoria or afferent pupillary defect was present. Intraocular

157. But It's Not All There. (Abstract)

But It's Not All There. A 44-year-old man presented with acute onset headache and isolated anisocoria. Dilation lag was noted in the smaller pupil and Horner syndrome was suspected despite the lack of eyelid ptosis. Cocaine testing confirmed the clinical diagnosis, and urgent neuroimaging found an internal carotid artery dissection. The patient was managed with systemic anticoagulation with a good final outcome. Horner syndrome should be suspected in any patient with aniscoria and dilation lag

158. Inequality of the direct and consensual light reflexes in normal subjects. Full Text available with Trip Pro

Inequality of the direct and consensual light reflexes in normal subjects. Anisocoria in darkness and during reflex responses to unilateral light stimulation was studied in 150 normal subjects with television pupillometry. It was commonly found that the direct light reaction of the stimulation eye exceeded the consensual reaction of the other eye. This light-induced anisocoria, termed 'contraction anisocoria', had a mean value of 0.075 mm or 6.1 % of light reflex amplitude. The measurement (...) showed a high degree of repeatability in 20 subjects who were tested on two occasions a year apart. It occurred in the presence and absence of prior dark adaptation and increased proportionally with reflex amplitude as the intensity of the stimulating light was raised. IT IS CONCLUDED THAT, CONTRARY TO PREVIOUS OPINION, A SMALL DEGREE OF CONTRACTION ANISOCORIA IS NORMAL.

159. Horner Syndrome

degenerated; the result is increased anisocoria. If the lesion is below the superior cervical ganglion (preganglionic or central Horner syndrome) and the postganglionic fibers are intact, the pupil of the affected eye also dilates, and anisocoria decreases. Apraclonidine : Apraclonidine is a weak alpha-adrenergic agonist that minimally dilates the pupil of a normal eye. If a postganglionic lesion is present (peripheral Horner syndrome), the pupil of the affected eye dilates much more than (...) that of the unaffected eye because the iris dilator muscle of the affected eye has lost its sympathetic innervation and has developed adrenergic supersensitivity. As a result, anisocoria decreases. (However, results may be falsely normal if the causative lesion is acute.) If the lesion is preganglionic (or a central Horner syndrome), the pupil of the affected eye does not dilate because the iris dilator muscle does not develop adrenergic supersensitivity; as a result, anisocoria increases. If results suggest Horner
