Purpose: To report an unusual case of intraocular cysticercosis in a 11-year-old boy that presented with chronic posterior uveitis and associated recalcitrant subfoveal and multifocal subretinal fluid blebs. The patient was later found to have a subsequent free-floating vitreous cyst that had been concealed from examination for years. Methods: Case report. Results: A diagnostic and therapeutic vitrectomy and cyst extraction revealed eosinophilic material suggestive of cysticercosis. Brain magnetic resonance imaging revealed suggestive neurocysticercosis and serological titers for cysticercosis immunoglobulin G were positive. After antihelminthic therapy and surgical removal of the cyst, the patient did well with complete resolution of multifocal subretinal fluid blebs and visual acuity improvement to 20/25. Conclusion: Ocular cysticercosis is a sight-threatening parasitic disease that can cause visually threatening manifestations if not identified and treated in a timely manner. Awareness of atypical presentations such as seen in this case in a pediatric patient is paramount.

Objective Optic nerve aplasia (ONA) is a rare ocular anomaly. We report ophthalmologic, systemic, and genetic findings in ONA. Methods Patients were identified through an International Pediatric Ophthalmology listserv and from the practice of the senior author. Participating Listserv physicians completed a data collection sheet. Children of all ages were included. Neuroimaging findings were also recorded. Results Nine cases of ONA are reported. Patients' ages ranged from 10 days to 2 years (median 9 months). Seven cases were bilateral. All patients had absence of the optic nerve and retinal vessels in the affected eye or eyes. Ophthalmologic findings included glaucoma, microcornea, persistent pupillary membrane, iris coloboma, aniridia, retinal dysplasia, retinal atrophy, chorioretinal coloboma, and persistent fetal vasculature. Systemic findings included facial dysmorphism, cardiac, genitourinary, skeletal, and developmental defects. A BCOR mutation was found in one patient. One patient had rudimentary optic nerves and chiasm on imaging. Conclusion ONA is a unilateral or bilateral condition that may be associated with anomalies of the anterior or posterior segment with or without systemic findings. Rudimentary optic nerve on neuroimaging in one case suggests that ONA is on the continuum of optic nerve hypoplasia.

The internet is a major source of health information for patients and parents. The information found online influences patients' and caregivers' understanding of diagnoses and decision making regarding management. We report the results of a survey completed by 4 fellowship-trained pediatric ophthalmologists evaluating the accuracy and clarity of various websites that provide information on amblyopia and strabismus.

OBJECTIVES: Increased intracranial pressure (ICP) has been suggested in legal settings as an alternative cause of retinal hemorrhages (RHs) in young children who may have sustained abusive head trauma. We assessed the prevalence and characteristics of RHs in children with increased ICP. METHODS: We conducted a prospective, multicenter study of children RESULTS: Fifty-six children (27 boys) were studied (mean age 15.4 months; range 1–43 months). All of the children had elevated ICP that required intervention. One child had papilledema. No child (0%; 95% confidence interval: 0%–6.4%) or eye (0%; 95% confidence interval: 0%–3.3%) was found to have an RH. Causes of increased ICP included hydrocephalus, intraventricular hemorrhage, congenital malformations, malfunctioning shunts, and the presence of intracranial space-occupying lesions. CONCLUSIONS: Although acute increased ICP can present in children with a pattern of peripapillary superficial RHs in the presence of papilledema, our study supports the conclusion that RHs rarely occur in the absence of optic disc swelling and do not present beyond the peripapillary area in the entities we have studied.

The antiepileptic drug vigabatrin is known to cause permanent loss of vision. Both visual field testing and electroretinogram are used to detect retinal damage. Adult data on optical coherence tomography (OCT) shows that retinal nerve fiber layer (RNFL) thinning may be an early indicator of vigabatrin-induced retinal toxicity. The purpose of this study was to investigate whether OCT can detect early vigabatrin-induced retinal toxicity in children.Pediatric patients (≤18 years of age) requiring vigabatrin for seizure control who were followed at our institution were invited to participate. Patients were examined according to manufacturer guidelines, with most examinations taking place under general anesthesia. RNFL thickness was measured by OCT (Stratus Model 3000, Zeiss) and compared to total cumulative dose of vigabatrin. In most cases, indirect ophthalmoscopy, fundus photography, and electroretinography were also performed.OCT and complete dosing data was available for 19 patients. Patients with tuberous sclerosis (TS, n = 12) received higher cumulative doses (mean, 1463 g) than non-TS patients (mean, 351 g, P = 0.044). RNFL thinning was detected in the nasal (P 0.01), superior (P 0.01), and inferior (P 0.05) quadrants in patients with TS, particularly once cumulative dose exceeded 1500 g.In our study population of patients with TS, higher cumulative doses of vigabatrin were associated with RNFL thinning in the nasal, superior, and inferior quadrants. These findings were pronounced once cumulative dose exceeded 1500 g. This pattern of RNFL thinning is similar to what has been shown in adult patients taking vigabatrin.
