Trends in Fluoroquinolone Nonsusceptibility Among Coagulase-Negative Staphylococcus Isolates Causing Endophthalmitis, 1995-2016.

This study investigates the susceptibilities of CoNS-causing endophthalmitis to fluoroquinolones over a 22-year time period at the Bascom Palmer Eye Institute, Miami, Florida, are reported.

Barriers to Glaucoma Medication Compliance Among Veterans: Dry Eye Symptoms and Anxiety Disorders.

Objective: To identify barriers to compliance of medical treatment for glaucoma among veterans.

Methods: Patients with glaucoma from the Miami Veterans Affairs Eye Clinic (n=74) filled out a 63-question survey regarding dry eye symptoms, concurrent systemic disease, and medications. The association between glaucoma medical compliance was defined as self-reported adherence to drop regimens greater than 75% of the time.

Evaluation of variables affecting intraoperative aberrometry.

Purpose: To understand some of the variable refractive changes that occur during routine cataract surgery that could affect the accuracy and effectiveness of intraoperative aberrometry as it relates to the postoperative refractive state.

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.

Pathology of 157 human cadaver eyes with round-edged or modern square-edged silicone intraocular lenses: analyses of capsule bag opacification.

Purpose: To assess the degree of capsular bag opacification in human cadaver eyes with silicone intraocular lenses (IOLs), specifically comparing the differences between round-edged IOLs and modern square-edged IOLs.

Setting: John A. Moran Eye Center, University of Utah, USA.

Pathology of 219 human cadaver eyes with 1-piece or 3-piece hydrophobic acrylic intraocular lenses: capsular bag opacification and sites of square-edged barrier breach.

Purpose: To assess capsular bag opacification and sites of initial posterior capsule opacification (PCO) in human cadaver eyes with square-edged 1-piece or 3-piece hydrophobic acrylic intraocular lenses (IOLs).

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.

Accelerated 20-year sunlight exposure simulation of a photochromic foldable intraocular lens in a rabbit model.

Purpose: To assess the long-term biocompatibility and photochromic stability of a new photochromic hydrophobic acrylic intraocular lens (IOL) under extended ultraviolet (UV) light exposure.

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.

Calcification of different designs of silicone intraocular lenses in eyes with asteroid hyalosis.

Purpose: To describe the association between calcification of older and newer designs of silicone intraocular lenses (IOLs) and asteroid hyalosis.

Design: Case series with clinicopathologic correlation.

Participants: Sixteen silicone IOLs explanted because of decreased visual acuity associated with opacifying deposits on the posterior optic surface.

Scanning electron microscopy visualization of methicillin-resistant Staphylococcus aureus after contact with gatifloxacin with and without preservative.

Purpose: To test a visual model by looking at the differences in effect of Zymar((R)) (gatifloxacin plus benzalkonium chloride [BAK]) when compared to gatifloxacin and a normal saline (NS) control upon a methicillin and gatifloxacin-resistant Staphylococcus aureus (MRSA) species.

Methods: An ocular isolate of gatifloxacin-resistant (minimal inhibitory concentration >2 to 4 microg/mL) MRSA was grown to confluency. Chambered slides were prepared with bacterial culture smears, and then incubated with either gatifloxacin at the concentrations of 1 and 10 microg/mL, Zymar containing equivalent concentrations of gatifloxacin, or NS.

Does expansion thoracoplasty improve the volume of the convex lung in a windswept thorax?

Background: Expansion thoracoplasty using the Vertical Expandable Prosthetic Titanium Rib increases the measured height and volume of the concave hemi thorax, but the effect on the convex, non-instrumented lung is unknown. The purpose of this study was to measure changes in lung volume and density in the convex lung after expansion thoracoplasty.

Methods: The volume and density of the lungs was measured in 12 children with congenital scoliosis and fused ribs before and after concave expansion thoracoplasty using serial computed tomography scans.

Comparison of the corneal endothelial protective effects of Healon-D and Viscoat.

Background: The use of dispersive ophthalmic viscosurgical devices (OVDs) has been shown to provide significant protection against air bubble damage to the corneal endothelium when compared with cohesive OVDs. We compared the corneal endothelial protective effects of a new dispersive OVD, Healon-D, with Viscoat.

Methods: Healon-D and Viscoat were used in a randomized and masked fashion in the anterior chamber of 40 rabbit eyes during a procedure where ultrasound at 70% continuous energy was delivered for 2 min.

Corneal transparency: genesis, maintenance and dysfunction.

Optimal vision is contingent upon transparency of the cornea. Corneal neovascularization, trauma and, surgical procedures such as photorefractive keratectomy and graft rejection after penetrating keratoplasty can lead to corneal opacification. In this article we identify the underlying basis of corneal transparency and factors that compromise the integrity of the cornea.

Late in-the-bag spontaneous intraocular lens dislocation: evaluation of 86 consecutive cases.

Objective: As techniques for cataract surgery have evolved, spontaneous intraocular lens (IOL) dislocation has decreased overall. However, since 2006 the Intermountain Ocular Research Center has received an increased number of explanted IOLs within the capsular bag forwarded for pathologic evaluation. Late, spontaneous dislocation of IOLs results from zonular insufficiency and zonulysis that has been associated with pseudoexfoliation, trauma, and other risk factors.
