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.

The Assessment Of Disability Related To Vision Performance-Based Measure In Diabetic Retinopathy., Kevin J. Warrian, Luciano L. Lorenzana, Dara Lankaranian, Jyoti Dugar, Sheryl S. Wizov, George L. Spaeth

Wills Eye Hospital Papers

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

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 …
