Objective: To obtain physicians' "real-world" perspectives on early experiences with triamcinolone acetonide suprachoroidal injection (SCS-TA) for treatment of patients with uveitic macular edema (UME).

Results: Twelve retina/uveitis specialists in the United States were surveyed about SCS-TA injection procedure and patient outcomes. Survey participants administered ≥ 291 SCS-TA injections to 243 patients with UME with various disease characteristics (etiologies, chronicity, and anatomical subtypes).

How do teachers' gestures influence students' learning? This article reviews research investigating the role of gestures in communication, focusing on teachers' communication with their students, primarily in mathematics and science instruction. We first briefly consider gesture's role in communication more generally as a backdrop for considering teaching as a special context for communication. We then describe teachers' spontaneous gesturing in teaching contexts, and we consider how teachers' spontaneous gestures might influence students' learning.

Background: While sutureless, cryopreserved amniotic membrane (cAM) has been shown to significantly improve signs and symptoms of dry eye disease (DED), no studies have assessed the association of cAM treatment duration to the differential response in clinical outcomes.

Methods: A multi-center, retrospective study was conducted on patients with moderate-to-severe DED who were treated with self-retained cAM (Prokera Slim) for 2 to 7 days. The primary outcome measure was DEWS severity score assessed at 1 week, 1 month, and 3 months.

Spastic cerebral palsy (CP) is a movement disorder marked by hypertonia and hyperreflexia; the most prevalent comorbidity is pain. Since spinal nociceptive afferents contribute to both the sensation of painful stimuli as well as reflex circuits involved in movement, we investigated the relationship between prenatal hypoxia-ischemia (HI) injury which can cause CP, and possible changes in spinal nociceptive circuitry. To do this, we examined nociceptive afferents and mechanical and thermal sensitivity of New Zealand White rabbit kits after prenatal HI or a sham surgical procedure.

Purpose: To assess the long-term safety and efficacy of the 0.19-mg fluocinolone acetonide (FAc) intravitreal implant (Iluvien; Alimera Sciences, Inc) in patients with diabetic macular edema (DME).

Design: Three-year, phase 4, nonrandomized, open-label observational study.

Background: This post hoc analysis compared the efficacy and safety of suprachoroidally administered triamcinolone acetonide (CLS-TA) to other commonly available treatments for non-infectious uveitis.

Methods: Results from the PEACHTREE study were compared between subjects randomised to CLS-TA not requiring rescue therapy and those subjects randomised to control, who subsequently required rescue therapy. Endpoints included best corrected visual acuity (BCVA), central subfield thickness (CST), treatment emergent adverse events and intraocular pressure (IOP) related safety findings.

Background And Objective: Characterize timing of intraocular pressure (IOP) elevation in patients treated with fluocinolone acetonide insert (FAi) for uveitis.

Patients And Methods: A post-hoc subset analysis of data from a randomized, prospective, double-masked, sham-controlled, 3-year, phase 3 clinical trial with 129 participants with noninfectious posterior uveitis randomly assigned to receive 0.18-mg fluocinolone acetonide insert or sham injection.

Given the success in stabilizing vision with current anti-vascular endothelial growth factor (VEGF) options, one main target for future anti-VEGF drug development includes creating medications with longer durations of action. Achieving this goal will decrease the number of overall injections and follow-up visits required to ensure better patient compliance. The smallest anti-VEGF created so far is brolucizumab (Beovu; Novartis).

Background And Objective: Exploratory investigation of the effect of diabetic macular edema (DME) control with the 0.2 µg/day fluocinolone acetonide (FAc) intravitreal implant on quality of life (QOL) outcomes.

Patients And Methods: Post-hoc analysis of patients from the FAME study who received the FAc implant and had answered the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25) at baseline and Year 3 (N = 324).

Background: Prior efforts evaluating obesity as a risk factor for postoperative complications following proctectomy have been limited by sample size and uniform outcome classification.

Methods: The ACS NSQIP was queried for patients with non-metastatic rectal adenocarcinoma who underwent elective proctectomy. After stratification by BMI classification, multivariable modeling was used to identify the effect of BMI class on adjusted risk of 30-day outcomes controlling for patient, procedure, and tumor factors.

Enhanced recovery after surgery (ERAS) is a multimodal protocol applied towards perioperative patient care. ERAS programs are implemented by a multidisciplinary team centered around the patient, incorporating outpatient clinical staff, preoperative nurses, anesthesiologists, operative nurses, postoperative recovery staff, floor inpatient nurses, dieticians, physical therapists, social workers, and surgeons. Initial studies on perioperative care measures focused on cardiac surgery.

Purpose: Central serous chorioretinopathy (CSCR) is a common retinopathy that is often observed until resolution. The purpose of this study is to evaluate the effects of topical nonsteroidal anti-inflammatory drugs (NSAIDs) on timing of CSCR recovery.

Methods: An IRB-approved retrospective review was conducted on patients that had been diagnosed with a new-onset, symptomatic case of CSCR.

The dexamethasone (DEX) implant is known to cause temporary intraocular pressure (IOP) spikes after implantation. The purpose of this study is to determine if IOP spikes after DEX implant cause significant thinning in the retinal nerve fiber layer (RNFL). A total of 306 charts were reviewed with 48 and 21 patients meeting inclusion criteria for the cross-sectional and prospective groups, respectively.

Anastomotic leak after lower gastrointestinal surgery is a complication with potential for high morbidity, mortality, and increased costs. A single-institution retrospective chart review was performed on all patients who underwent lower gastrointestinal surgery between June 2009 and June 2013. Fifty-seven variables were included in our analysis and their association with postoperative anastomotic leak was examined.
