Corneal cross-linking for treatment of keratoconus relapse in post-keratoplasty eyes.

Purpose: Keratoconus relapse after penetrating keratoplasty is a rare condition that may result in severe visual deterioration and corneal graft thinning. Therefore, treatment to stabilize the cornea should be considered. The purpose of this study was to evaluate the safety and efficacy of Corneal Cross-Linking (CXL) in eyes with relapse of keratoconus after penetrating keratoplasty for keratoconus.

Thicker macula in asymptomatic Ɛ4 middle-aged adults at high AD risk.

Introduction: We compared retinal layers' thickness between apolipoprotein E () Ɛ4 carriers and non-carriers in a cohort of cognitively normal middle-aged adults enriched for Alzheimer's disease (AD) risk.

Methods: Participants (N = 245) underwent spectral domain optical coherence tomography. Multivariate analyses of covariance adjusting for age, sex, education, and best corrected vision acuity was used to compare retinal thickness between groups.

Radiation dose reduction for chest radiography of infants in intensive care units using a high peak kilovoltage-technique.

Background: Chest radiography is an important tool in the care of infants in intensive care units. Image optimization must be monitored to minimize radiation exposure in this susceptible population.

Objective: To examine the use of a high tube peak kilovoltage technique to achieve radiation dose reduction while maintaining adequate image quality.

COVID-19's Influence on Ocular Emergency Visits at a Tertiary Referral Center and Its Relationship to Emergency Indications by the American Academy of Ophthalmology.

Purpose: To examine the trends of ocular emergency admissions during the COVID-19 pandemic at a tertiary care center.

Methods: The study's sample consisted of all patients who were seen in the ophthalmic emergency room (OER) between March 15 and April 15, 2020 (during the COVID-19 pandemic) and in the same time frame of the previous year. The cases were categorized as urgent vs.

Efficacy of Vismodegib for the Treatment of Orbital and Advanced Periocular Basal Cell Carcinoma.

Purpose: To evaluate the effectiveness of vismodegib, a Hedgehog pathway inhibitor, in treating orbital and advanced periocular basal cell carcinoma (BCC) in Israeli multidisciplinary medical centers.

Design: Retrospective case series.

Methods: Background, treatment, and outcome data were retrospectively collected from the medical records of all patients with locally advanced and metastatic orbital or periocular BCC treated with vismodegib in 2012-2017 at 2 tertiary medical centers.

OUTCOMES OF RHEGMATOGENOUS RETINAL DETACHMENT REPAIR AFTER FAILED PNEUMATIC RETINOPEXY.

Purpose: To evaluate the visual and anatomical outcomes of reoperations following failure of pneumatic retinopexy (PR) for rhegmatogenous retinal detachment repair and compare the different surgical techniques used in these cases.

Methods: The study included 114 eyes of 114 patients who underwent PR for rhegmatogenous retinal detachment and required subsequent surgery for its repair. These included repeated PR, scleral buckling, vitrectomy with gas or silicone oil, and vitrectomy with scleral buckling.
