We describe a dataset of several thousand calibrated, time-stamped, geo-referenced, high dynamic range color images, acquired under uncontrolled, variable illumination conditions in an outdoor region spanning several hundred meters. The image data is grouped into several regions which have little mutual inter-visibility. For each group, the calibration data(More)
PURPOSE To assess light scattering and light transmittance in intraocular lenses (IOLs) explanted because of optic opacification. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Experimental study. METHODS Poly(methyl methacrylate) (PMMA) IOLs with snowflake degeneration, hydrophilic acrylic IOLs with different(More)
PURPOSE To assess the potential effect of surface light scattering on light transmittance of 1-piece hydrophobic acrylic intraocular lenses (IOLs) with or without a blue-light filter. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Experimental study. METHODS Intraocular lenses were obtained from human cadavers(More)
PURPOSE To determine how the most common risk factors for toxic anterior segment syndrome (TASS) have evolved over the past decade. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Cross-sectional study. METHODS This was a retrospective analysis of surveys from centers reporting cases of TASS from June 1, 2007,(More)
We analyzed an enucleated eye that was blind and painful from a 66-year-old patient implanted with a Tennant modification of the Choyce Mark VIII anterior chamber intraocular lens (IOL) as a secondary procedure in 1978. The eye developed glaucoma, with implantation of an Ahmed valve in 2006. Gross and light microscopic analyses showed corneal decompensation(More)
PURPOSE To evaluate the stability and capsular bag opacification with a modified disk-shaped 1-piece hydrophilic acrylic intraocular lens (IOL) suspended between 2 complete haptic rings connected by a pillar of the haptic material and with a commercially available 1-piece hydrophilic acrylic IOL. SETTING John A. Moran Eye Center, University of Utah, Salt(More)
Portomesenteric venous thrombosis (PMVT) is an uncommon complication of abdominal surgery. The objective of this study was to assess PMVT risk factor profiles and patient outcomes after colorectal surgery. A single center retrospective review of patients undergoing colorectal surgery was performed (2007–2012). PMVT was defined as thrombus within the portal,(More)
PURPOSE To evaluate the biocompatibility and capsular bag opacification of an accommodating intraocular lens (IOL) containing large haptic elements that separate the anterior and posterior capsules. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Experimental study. METHODS Bilateral phacoemulsification with IOL(More)
PURPOSE To evaluate the use of anterior segment optical coherence tomography (AS-OCT) to assess postoperative intraocular lens (IOL) optic changes. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Experimental study. METHODS Intraocular lenses explanted because of various complications were used, including(More)
We present a 33-year-old dialysis-dependent female who presented with new onset split second heart sound. Following a failed left upper extremity dialysis fistula, a right upper extremity hemodialysis reliable outflow (HeRO) graft was performed in 2011. Her subsequent cadaveric renal transplant had delayed function necessitating concurrent use of(More)
