Seasonal Variation in the Incidence of Malignant Glaucoma after Cataract Surgery.

Purpose: To investigate a potential link between the incidence of malignant glaucoma after cataract surgery and seasonal variations in daylight.

Methods: In total, 18,374 uncomplicated cataract surgeries were performed between June 2008 and June 2013 at an ambulatory surgery center in Toronto. Toronto's average monthly daylight over that time period-in hours per day for each month-was determined.

Assessing Progression of Resident Proficiency during Ophthalmology Residency Training: Utility of Serial Clinical Skill Evaluations.

Objective: The Accreditation Council for Graduate Medical Education (ACGME) has mandated that residency programs document progression of competency-based outcomes. The Ophthalmic Clinical Evaluation Exercise (OCEX) assesses clinical skills in ophthalmology residents during patient encounters. Although OCEX has been validated for assessing several of the ACGME-mandated competencies, it was unclear whether OCEX can measure the development of proficiency during residency.

Patch graft materials for glaucoma tube implants.

Purpose Of Review: Patch graft materials serve multiple purposes in glaucoma surgery. There are several choices of patch graft materials from which the surgeon can choose. Therefore, knowledge as to the choices and the potential risks and benefits of patch graft materials is imperative for the glaucoma surgeon.

Biocompatibility of a Novel Microfistula Implant in Nonprimate Mammals for the Surgical Treatment of Glaucoma.

Purpose: The purpose of this study was to evaluate the ocular safety of a novel microfistula implant and its composite materials in an animal model.

Methods: The anterior chambers of 12 rabbit eyes were injected with either glutaraldehyde cross-linked porcine gelatin extract or balanced salt solution and were followed by serial slit lamp examinations over 3 days. The eyes of 18 canines underwent microfistula implantation or a sham procedure.

Space: The Final Frontier for IR.

A manned mission to Mars requires advanced on-board medical capabilities to address medical incidents that may arise during long-duration interplanetary spaceflight. As this role does not exactly match that of any single specialty, the ideal choice of physician is not immediately obvious. In this work, we review the considerable challenges of providing medical care in the austere conditions of interplanetary space travel and explain why an interventional radiologist may be well-equipped to deliver diagnostic and therapeutic care within these severely constrained conditions.

A site-specific bifunctional protein labeling system for affinity and fluorescent analysis.

Most covalent protein labeling schemes require a choice between visual and affinity properties, requiring the use of multiple fusion systems where both attributes are needed. While not disruptive at the single experiment level, this detail becomes critical when addressing high-throughput experimentation. Here we develop a uniform site-specific protein tag for use in both fluorescent and affinity screening.
