Safety of 3 Tesla Magnetic Resonance Imaging on iStent Implants: An Ex-Vivo Study.

Prcis: Our study shows that iStent implant does not cause significant image artifacts, heating, or displacement during magnetic resonance imaging (MRI) scan. This device can be safely used in patients undergoing MRI scans using 3 Tesla (3T) machines.

Purpose: The iStent is a medical grade titanium implant commonly implanted in the anterior chamber angle of glaucomatous eyes in order to reduce intraocular pressure and medication burden.

The effect of hemodialysis on individual retinal layer thickness.

Purpose: The aim of this study was to employ newly developed advanced image analysis software to evaluate changes in retinal layer thickness following hemodialysis.

Methods: A non-randomized prospective study of patients with end-stage renal disease assessed on the same day before and after hemodialysis. Intraocular pressure and central corneal thickness were analyzed, and spectral domain optical coherence tomography results were automatically segmented using the Orion software and then compared.

Effect of Rho-associated kinase inhibitor on human corneal endothelial cell apoptosis.

Purpose: To evaluate whether exposure to Rho-associated protein kinase (ROCK) inhibitor will promote human-cultured corneal endothelial cells (CECs) survival in a commercial storage medium.

Setting: Edith Wolfson Medical Center, Holon, and Sheba Medical Center, Tel Hashomer, Israel.

Design: Experimental study.

Prophylactic exposure of human corneal endothelial cells to Rho-associated kinase inhibitor reduced apoptosis rate after phacoemulsification: Ex vivo study.

Purpose: To evaluate whether prophylactic exposure of corneal endothelial cells (CECs) to a selective Rho-associated kinase (ROCK) inhibitor will inhibit CEC apoptosis after phacoemulsification.

Setting: Laboratory evaluations at the Edith Wolfson Medical Center, Holon, Israel and the Chaim Sheba Medical Center, Tel-Hashomer, Ramat-Gan, Israel and the Chaim Sheba Medical Center, Tel-Hashomer, Ramat-Gan, Israel.

Design: Experimental study.

Photoreceptor Integrity Predicts Response to Anti-VEGF Treatment.

Purpose: Assessing changes in foveal photoreceptor microstructure (FPM) following intravitreal anti-VEGF treatment may serve as a prognostic marker in patients with macular edema (ME).

Methods: Sixteen eyes belonging to newly diagnosed patients with ME were included in this prospective longitudinal study. FPM integrity was evaluated at baseline and at the end of a series of anti-VEGF injections.

Comparison of the Tolerability of Diclofenac and Nepafenac.

Purpose: Topical nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for the prevention and treatment of inflammation and pain following cataract surgery. Preservative-free diclofenac and nepafenac drops are commonly used ophthalmic NSAIDs. The purpose of this study was to compare the tolerability of diclofenac to that of nepafenac.

Quantification of metamorphopsia using the MacuFlow test before and after vitreoretinal surgery.

Background And Objective: This pilot study evaluated the clinical utility of the MacuFlow software in measuring metamorphopsia prior to and following surgery in patients with vitreoretinal diseases.

Patients And Methods: Four patients with vitreoretinal disorders causing metamorphopsia were included in this pilot study. Visual acuity (VA), optical coherence tomography and MacuFlow scores were recorded prior to and following surgical intervention.

Minimal astigmatism after sutureless planned extracapsular cataract extraction.

Purpose: To evaluate astigmatism after mini-nuc extracapsular cataract extraction (ECCE) in which a chevron incision is enlarged to 6.0 to 7.0 mm for easier nucleus removal and to compare the results with those using a 5.
