The Pipeline Embolization Device (PED) is a flow diverting stent used in the treatment of a wide variety of intracranial aneurysms. The device differs from traditional stents used in stent-assisted coil embolization in that it has a tighter lattice structure with smaller cell sizes designed specifically to disrupt blood flow into aneurysms rather than only to retain coils within aneurysms. While the PED has been shown to be safe and effective, it has a unique risk profile that includes side branch and perforator vessel occlusion...

INTRODUCTION: Interpretation of perimetric findings, particularly in children, relies on accurate assessment of test reliability, yet no objective measures of reliability exist for kinetic perimetry. We developed the kinetic perimetry reliability measure (KPRM), a quantitative measure of perimetric test reproducibility/reliability and report here its feasibility and association with subjective assessment of reliability. METHODS: Children aged 5-15 years, without an ophthalmic condition that affects the visual field, were recruited from Moorfields Eye Hospital and underwent Goldmann perimetry as part of a wider research programme on perimetry in children...

PURPOSE: To identify and evaluate possible causes of poor patient-reported visual function after cataract surgery. METHODS: We obtained retrospective data from the Swedish National Cataract Register on patient self-assessed visual function before and after cataract surgery based on the Catquest-9SF questionnaire. We identified patients who self-reported similar or more difficulties postoperatively than preoperatively, and looked at possible causative variables such as sex, age, preoperative and postoperative corrected distance visual acuity (CDVA) and refractive errors, and ocular comorbidity...

An apprenticeship model has traditionally been used in procedural and surgical teaching. As the pressures of work hours and patient outcome monitoring increase, surgical teachers need a more flexible plan for teaching procedural skills. We attempt to delineate a program of pre-, intra-, and post- procedural teaching that can be used in the field of ophthalmology to maximize a resident's skill acquisition in a constructive learning environment.We review the literature on surgical teaching from within ophthalmology as well as other surgical fields and combine this with teaching experience in an ophthalmic surgical training program to produce a collection of procedural teaching guidelines...

Scanning laser ophthalmoscopy (SLO) benefits diagnostic imaging and therapeutic guidance by allowing for high-speed en face imaging of retinal structures. When combined with optical coherence tomography (OCT), SLO enables real-time aiming and retinal tracking and provides complementary information for post-acquisition volumetric co-registration, bulk motion compensation, and averaging. However, multimodality SLO-OCT systems generally require dedicated light sources, scanners, relay optics, detectors, and additional digitization and synchronization electronics, which increase system complexity...

This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead to devastating effects if malignant cells seed into the orbit and adjacent cranial nerves as our two patients developed an orbital apex syndrome...

BACKGROUND: Surgical removal of one or both eyes has been the most common way to treat children with retinoblastoma worldwide for more than 100 years. Ophthalmic artery chemosurgery (OAC) was introduced 10 years ago and it has been used as an alternative to enucleation for eyes with advanced retinoblastoma. The purpose of this report is to analyze our 9-year experience treating advanced retinoblastoma eyes with OAC. MATERIALS AND METHODS: Single-arm retrospective study from a single center of 226 eyes with eyes of retinoblastoma patients with advanced intraocular disease defined as both Reese-Ellsworth (RE) "Va" or "Vb" and International Classification Retinoblastoma (ICRb) group "D" or "E" (COG Classification)...

Retinal artery occlusion leads to profound visual impairment in the affected eye. It is rarely caused by local ophthalmic pathologies. Most patients present with a large number of cardio- and cerebrovascular risk factors. Visual loss is the leading symptom in central retinal artery occlusion (CRAO), whereas a circumscribed visual field defect is claimed in branch retinal artery occlusion (BRAO). Although many attempts have been made to improve the course of the disease, no effective therapy is available. There is some hope that intravenous fibrinolysis could influence the natural course but the therapeutic window is small (ca...

PURPOSE: The aim of this report was to demonstrate a case of Coats disease in a patient with concurrent anisometropic amblyopia. OBSERVATIONS: A 10-year-old boy was diagnosed with Coats disease during routine ophthalmic examination. Visual acuity was 20/20 OD and 20/50 OS with cycloplegic refraction of +1.25 (OD) and +3.25 (OS). Examination under anesthesia showed macular exudates in the left eye that encroached near the fovea superotemporally. Despite the poor visual acuity and macular exudates, the foveal architecture of both eyes appeared normal on spectral domain optical coherence tomography...
