Christopher Bowd, Linda M Zangwill, Robert N Weinreb, Felipe A Medeiros, Akram Belghith
PURPOSE: "Floor effects" in retinal imaging are defined as the points at which no further structural loss can be detected. We estimated the measurement floors for spectral-domain optical coherence tomography (SD-OCT) measurements and compared global change over time in advanced glaucoma eyes. DESIGN: Validity study to investigate measurement floors. METHODS: A longitudinal "Variability Group" of 41 eyes with moderate to advanced glaucoma (SAP MD ≤ -8 dB) was used to estimate measurement floors...

PURPOSE: Uveal metastases are ophthalmologic tumors that have historically been treated by fractionated external beam radiation therapy or invasive brachytherapy. The need for rapid response and less invasive management options led the authors to explore the use of Gamma knife stereotactic radiosurgery (SRS) for this common problem. DESIGN: Interventional case series. METHODS: Intervention: In order to prevent eye movement during the procedure, all three patients underwent a retrobulbar anesthetic block followed by magnetic resonance imaging to detect the target...

INTRODUCTION: Initial undercorrection of intra-ocular lens (IOL power) is a common practice in children undergoing pediatric cataract surgery. However, long term refractive status of these children is largely unknown. The purpose of this study is to analyze the long-term refractive status of these children.
