Purpose:
Vigabatrin can cause retinopathy, resulting in bilateral visual field constriction. Previous analyses of results from a prospective, observational study assessing vigabatrin-induced visual field constriction (described below) employed a partially subjective interpretation of static perimetery. In an effort to affirm these previous findings through more objective, quantitative methodology, we now report data from a subset analysis of refractory partial epilepsy patients in the study who underwent Goldmann kinetic perimetry.
Methods:
Patients aged ≥8 years with refractory partial seizures were enrolled and grouped: those receiving vigabatrin for ≥6 months (Group I); those who had received vigabatrin for ≥6 months and then …
Obstructive Sleep Apnea And Ocular Disorders., Deepak P. Grover
Obstructive Sleep Apnea And Ocular Disorders., Deepak P. Grover
Wills Eye Hospital Papers
PURPOSE OF REVIEW: Obstructive sleep apnea is a diagnosis that ophthalmologists can screen for when a patient presents with certain risk factors. Recent literature provides strong data for associations between sleep apnea and ocular disorders.
RECENT FINDINGS: A potentially serious disorder, sleep apnea can lead to many systemic and ocular complications. Recent findings provide data on the prevalence of sleep apnea with various disorders. Adequate treatment of sleep apnea has also shown to reverse both systemic and eye-related complications.
SUMMARY: Early diagnosis and management of sleep apnea is critical for reducing the risk of devastating systemic complications and preserving ocular …
Pediatric Ophthalmology And Strabismus: Something For Everyone., Alex V. Levin
Pediatric Ophthalmology And Strabismus: Something For Everyone., Alex V. Levin
Wills Eye Hospital Papers
This issue of Current Opinion in Ophthalmology highlights the uniquely broad range of pediatric ophthalmology and strabismus. Perhaps, unlike any other area of ophthalmology, our specialty covers virtually every part of the eye and a multitude of systemic disorders. Pediatric ophthalmology offers the practitioner the opportunity to impact a patient’s visual life for many decades giving them a lifetime of good vision. This issue of the journal highlights the many ways that this is so.

Convergence Insufficiency And Its Current Treatment., Judith B Lavrich
Wills Eye Hospital Papers
PURPOSE OF REVIEW: Considerable uncertainty and controversy has existed concerning the management of convergence insufficiency. Only recently there have been significant scientific studies published that compare the effectiveness of the commonly prescribed treatments. This paper reviews the most recent research and literature on convergence insufficiency and its treatment.
RECENT FINDINGS: The first large-scale placebo-controlled, randomized clinical trials to study the various treatments of convergence insufficiency have recently been published. Current research compares the effectiveness of base-in prism glasses, pencil push-ups, and vision therapy in reducing the signs and symptoms of convergence insufficiency and suggests that orthoptic therapy is the most …
Spontaneous Disconnection Of Glaucoma Tube Shunt Extenders., Oseluese Dawodu, Alex V. Levin
Spontaneous Disconnection Of Glaucoma Tube Shunt Extenders., Oseluese Dawodu, Alex V. Levin
Wills Eye Hospital Papers
Glaucoma drainage implants are frequently used in children with severe forms of glaucoma, and tube extenders are sometimes required to compensate for ocular growth or when the intraocular portion of the tube is thought to be too short. We report 2 cases of spontaneous disconnection of a tube extender, occurring 8 months after insertion in one case and 3 years later in the other. In both cases the tube was removed and the patient treated with endoscopic diode laser photocoagulation.

PURPOSE: To validate a third-generation performance-based measure of visual function titled "Assessment of Disability Related to Vision" (ADREV) in a study population of patients with diabetic retinopathy.
DESIGN: Prospective, cross-sectional study.
METHODS: Patients with nonproliferative or proliferative diabetic retinopathy, free from ocular comorbidity, were recruited from a single institute and completed the ADREV, the 25-Item National Eye Institute Visual Functioning Questionnaire (VFQ-25), and a clinical ophthalmic examination. Correlation, regression, and bootstrap analysis were conducted to determine the relationship between ADREV scoring and each of the study's clinical and self-report measures of visual ability, while controlling for potential confounders.
RESULTS: Ninety-one …
Differential Gene Expression Profile Of Retinoblastoma Compared To Normal Retina., Arupa Ganguly, Carol L Shields
Differential Gene Expression Profile Of Retinoblastoma Compared To Normal Retina., Arupa Ganguly, Carol L Shields
Wills Eye Hospital Papers
PURPOSE: The retinoblastoma gene (RB1) is a tumor suppressor gene that was first discovered in a rare ocular pediatric tumor called retinoblastoma (RB). The RB1 gene is essential for normal progression through the cell cycle and exerts part of its function through the family of transcription factors (E2F) and many other intermediaries. In the absence of normal RB1, genomic instability and chromosomal aberrations accumulate, leading to tumor initiation, progression, and ultimately metastasis. The purpose of this report was to identify the molecular pathways that are deregulated in retinoblastoma.
METHODS: We compared gene expression signatures of matched normal retinal tissue and …
