Background: Various imaging modalities play a role in diagnosing parasitic infections of the eye. We describe the spectral domain optical coherence tomography (SD-OCT) findings of an intravitreal parasite with subsequent evaluation by light microscopy.
Findings: This is a case report of a 37-year-old Ecuadorian man who presented with uveitic glaucoma and a new floater in his left eye for 1 week's duration.
The aim of this study is to determine the incidence of cystoid macular edema (CME) following repositioning and McCannel iris-suturing of dislocated intraocular lenses. This study is conducted in an urban private practice. A retrospective chart review was performed on consecutive patients who presented with posteriorly dislocated IOLs and underwent iris-sutured posterior chamber (PC) intraocular lens (IOL) placement using the McCannel suture technique by a single surgeon for IOL repositioning from December 2008 to August 2012.

This observational case series consists of three eyes from three patients seen between 2005 and 2012. Delayed idiopathic macular hole formation occurred following demarcation laser photocoagulation for subclinical retinal detachment.

Methods: This was a comparative case series of expert versus nonexpert clinicians in image-based ROP diagnosis. An atlas of 804 retinal images was captured from 248 eyes of 67 premature infants with a wide-angle camera (RetCam-II, Clarity Medical Systems, Pleasanton, CA).
Purpose: To measure accuracy and speed for detection of vascular progression in retinopathy of prematurity (ROP) from serial images. Two strategies are compared: static side-by-side presentation and dynamic flickering of superimposed image pairs.
Design: Prospective comparative study.

Despite advances in optical coherence tomography (OCT), three-dimensional (3D) renderings of OCT images remain limited to scanning consecutive two-dimensional (2D) OCT slices. The authors describe a method of reconstructing 2D OCT data for 3D retinal analysis and visualization in a Computer Assisted Virtual Environment (CAVE). Using customized signal processing software, raw data from 2D slice-based spectral-domain OCT images were rendered into high-resolution 3D images for segmentation and quantification analysis.

Methods: Baseline demographic data, surgical procedures, and outcomes from 230 patients with a diagnosis of primary rhegmatogenous RD, who underwent surgery between January 2007 and December 2008 at the Rudolf Foundation Clinic, Vienna (Center 1) and the Weill Cornell Medical College, New York, (Center 2) were analyzed using a regression model.
Results: Besides the baseline parameters, lens status (P = 0.
Purpose: This pilot study investigated whether high-resolution spectral-domain optical coherence tomography (SD-OCT) could detect differences in inner retinal layer (IRL), peripapillary retinal nerve fiber layer (RNFL), and macular thickness between patients with Parkinson's disease (PD) and controls.
Methods: Both eyes of patients with PD and age-matched controls were imaged with the Heidelberg Spectralis(®) HRA + OCT. RNFL, IRL, and macular thickness were measured for each eye using Heidelberg software.

Purpose: To report our experience with dexamethasone 0.7 mg sustained-release intravitreal implant (Ozurdex(®); Allergan, Inc, Irvine, CA) in noninfectious posterior uveitis.
Methods: A retrospective chart review of patients with noninfectious uveitis treated with sustained-release dexamethasone 0.
Purpose: The purpose of this study was to report long-term results of intravitreal antivascular endothelial growth factor therapy in the management of choroidal neovascularization in patients with angioid streaks associated with pseudoxanthoma elasticum.
Methods: A consecutive series of patients with pseudoxanthoma elasticum and choroidal neovascularization were managed with intravitreal antivascular endothelial growth factor injections (bevacizumab 1.25 mg/0.
