Wills Eye Hospital Papers
PURPOSE: To evaluate retinoblastoma control after intravenous chemotherapy (chemoreduction) by patient age at presentation.
DESIGN: Retrospective case series.
METHODS: This study included 964 eyes of 554 patients treated with chemoreduction at Ocular Oncology Service at Wills Eye Hospital. Patients received 6 monthly cycles of standard chemoreduction. Additional therapies for tumor control were performed as needed.
RESULTS: Of 964 eyes, a comparison by age group (24 months) revealed more advanced age group with higher frequency of group E tumor (15% vs. 25% vs. 32% vs. 39%, P < 0.001). By treatment outcomes, complete tumor control was achieved with chemoreduction alone more often in less advanced age group (46% vs. 30% vs. 17% vs. 8%, P < 0.001). Additional treatment after chemoreduction was needed more often in more advanced age group with external beam radiotherapy (EBRT; 9% vs. 16% vs. 20% vs. 15%, P = 0.006) or enucleation (12% vs. 18% vs. 26% vs. 37%, P < 0.001). Over time (1994-1998 vs. 1999-2003 vs. 2004-2008 vs. 2009-2013 vs. 2014-2019), the paradigm for additional required treatment after chemoreduction shifted toward less EBRT (27% vs. 24% vs. 14% vs. 7% vs. 2%, P < 0.001) and more intra-arterial (0% vs. 0% vs. 1% vs. 25% vs. 48%, P < 0.001) and intravitreal (0% vs. 0% vs. 3% vs. 10% vs. 20%, P < 0.001) chemotherapy.
CONCLUSIONS: Chemoreduction is a safe and effective treatment method for patients with retinoblastoma, demonstrating …

Screening Amblyopic Risk Factors In A Pediatric Population Using An Automated Vision Screener, Rebecca Dawn Slominski
Evidence-Based Practice Project Reports
Amblyopia is the most common visual disorder in children and is potentially curable if detected early and treated properly in the first few years of life. Amblyopia is the leading cause of monocular vision loss in children (Bradfield, 2013). It is a developmental neuroplasticity which derives from birth causing structural and functional changes in the eye and brain. With this structural and functional disruption, visual blur occurs due to refractive amblyopia, strabismic amblyopia, cataracts (form-deprivation amblyopia), or a combination of any of these (Solebo, Cumberland, & Rahi, 2015). Refractive errors related to amblyopia can also occur. The purpose of this …

Accurate, real-time identification and display of critical anatomic structures, such as the nerve and vasculature structures, are critical for reducing complications and improving surgical outcomes. Human vision is frequently limited in clearly distinguishing and contrasting these structures. We present a novel imaging system, which enables noninvasive visualization of critical anatomic structures during surgical dissection. Peripheral nerves are visualized by a snapshot polarimetry that calculates the anisotropic optical properties. Vascular structures, both venous and arterial, are identified and monitored in real-time using a near-infrared laser-speckle-contrast imaging. We evaluate the system by performing in vivo animal studies with qualitative comparison by contrast-agent-aided …

Introduction: Retinopathy of prematurity (ROP) is a treatable cause of blindness in neonates. In Pakistan, ROP is often not recognized early because screening and treatment programs are not yet in place in most neonatal units, even in tertiary care hospitals. It is hoped that this report will help inform medical professionals of the magnitude of the problem and help to design appropriate management strategies.
Objectives: The aim was to determine the frequency of ROP in premature and very low birth weight (BW) neonates (BW(GA)weeks).
Study Design: Cross-sectional study.
Study Setting : Neonatal intensive care unit (NICU) of a tertiary care …
