Mice immunized with MLAA-34236-244 vaccine had increased percentages of MLAA-34236-244 tetramer+ CD8+ T cells in the spleen after each round of immunization. High-purity CD8+ and CD4+ T cells were sorted by Dynabeads as effector cells. The killing activity of CD8+ T cells was higher than that of CD4+ T cells. CTLs derived from the MLAA-34 peptide vaccine group were significantly higher than other therapeutic groups and showed specific cytotoxicity to THP-1 cells. Increased interferon-γ and interleukin (IL)-2 and decreased IL-10 and IL-4 were seen in the MLAA-34236-244 peptide vaccine group. MLAA-34236-244 peptide (ILDRHNFAI) is an effective HLA-A*0201-restricted CTL epitope and that it may serve as a promising strategy in designing antigen-specific immunotherapy against MLAA-34-positive acute monocytic leukemia.
The agreement between a head-mounted perimeter [GearVision (GV)] and Humphrey field analyzer (HFA) for total threshold sensitivity was a mean difference of -1.9 dB (95% limits of agreement -5 to 1). check details GV was the preferred perimeter in 68.2% of participants.

The purpose of this study was to compare reliability indices and threshold sensitivities obtained using a novel, smartphone-based, head-mounted perimeter (GV) with the HFA in normal, glaucoma suspect and glaucoma patients. link2 A secondary objective was to evaluate the subjective experience participants had with both perimeters using a questionnaire.

In a prospective, cross-sectional study; 107 eyes (34 glaucoma, 18 glaucoma suspect, and 55 normal) of 54 participants underwent HFA and GV in random order. The main outcome measure was the agreement of threshold sensitivities using Bland and Altman analysis. Participants also completed a questionnaire about their experience with the devices.

Median false-positive response rate for GV was 7% (4% to 12%), whilortable or home perimeter.
A lower baseline corneal hysteresis and a decrease in corneal resistance factor (CRF) over time are associated with higher risk of visual field progression in glaucomatous and glaucoma suspect eyes.

The aim was to investigate the longitudinal change in CRF and cornea hysteresis (CH) as risk factors for visual field progression.

In this prospective observational cohort study, 72 eyes of 48 glaucoma or glaucoma suspect patients were followed for an average of 4.5 years. Baseline and follow-up CH and CRF measurements were performed with the Ocular Response Analyzer (Reichert Ophthalmic Instruments Inc., Depew, N.Y.). Evaluation of rates of visual field change during follow-up was performed using visual field mean deviation. Univariable and multivariable linear mixed models assessed the relationship of visual field progression with baseline CRF and CH as well as with changes in CRF and CH.

The mean baseline CH was 9.0 (95% confidence interval 8.6-9.4)  mm Hg and the mean baseline CRF was 9.3 (95% confidenes at highest risk of visual field progression.
Tono-Pen AVIA (TPA) intraocular pressure (IOP) values are different from those taken with handheld Goldmann applanation tonometer (GAT) in primary congenital glaucoma (PCG). These differences indicate both tonometers cannot be used interchangeably for measuring IOP in PCG.

The aim was to compare IOP measurements obtained using TPA and a handheld version of GAT in children with PCG.

Forty-two eyes from 23 patients were evaluated for central corneal thickness (CCT), axial length, biomicroscopy and IOP measurement with TPA and a handheld GAT under inhalation anesthesia. link3 After 1 eye from each patient was randomized, paired the Student t-test and the Pearson correlation were used for analysis. Generalized linear mixed model was used to estimate the difference between tonometers.

Mean age of children was 28.3±20.5 months. Mean axial length was 24.89±3.33 mm and mean CCT was 605.9±81.0 µm. Mean IOP was 22.1±9.6 for TPA and 14.0±4.5 mm Hg for GAT. There was a significant difference of 8.1±6.9 mm Hg between TPA IOP and GAT IOP (P<0.001). Each 6 months increase in age was associated with 1.32 mm Hg reduction in the difference between tonometers (P=0.002) and each 1 mm Hg higher of mean GAT IOP was associated with -0.73 mm Hg in the difference between TPA and GAT (P=0.002). Also, for every 20 µm increase in CCT an increase of 1.16 mm Hg in the difference between both devices was expected (P=0.003), after adjustment for potentially confounding variables.

There is a significant difference between TPA IOP and GAT IOP in PCG. The difference between TPA and GAT in PCG is influenced by CCT, age and GAT IOP value.

The Michigan Screening and Intervention for Glaucoma and eye Health through Telemedicine (MI-SIGHT) program leverages community-engaged research, telemedicine, and health coaching to overcome key logistical and psychosocial barriers to improve glaucoma screening in underserved communities.

To describe the methodology of the implementation and evaluation of the MI-SIGHT Program.

The MI-SIGHT Program uses community engagement, telemedicine, and health coaching to overcome key logistical and psychosocial barriers to glaucoma identification and care among underserved populations. The MI-SIGHT Program will be evaluated in 2 community clinics Hamilton Community Health Network, a federally qualified health center in Flint, Michigan, and the Hope Clinic, a free clinic in Ypsilanti, Michigan. A Community Advisory Board including the research team and health care providers, administrators, and patients from both clinics will guide program implementation. An ophthalmic technician at the community clinics will condn high-risk communities.
Ahmed glaucoma valve (AGV) implantation without plate fixation resulted in high rates of complications related to plate or tube movement.

Scleral suturing of the plate of AGV is associated with technical difficulty and potential complications. This study summarizes the surgical outcomes of 10 years of experience with AGV implantation without suture plate fixation.

The medical records of all glaucoma patients who underwent AGV implantation surgery without plate fixation between 2009 and 2019 at the Sheba Medical Center (Tel Hashomer, Israel) were retrospectively reviewed. Clinical data on intraoperative and postoperative complications, best-corrected visual acuity, intraocular pressure, and number of intraocular pressure-lowering medications were retrieved.

Included were 95 eyes of 95 patients (53 men, 42 women; mean age, 54.9±17.5 y). The mean follow-up was 687±673 days. In total, 37 patients (37/95, 38.%) had AGV-related complications, of whom 28 (29.5%) required additional intervention. Women had a significantly higher rate of complications than men (21/42, 50% vs. 16/53, 30.2%, respectively, P=0.049). The 2 most common complications were AGV migration in 13 eyes (13.7%) and tube exposure/AGV extrusion in 9 eyes (9.5%). AGV was removed in 10 cases.

In this cohort, omitting suture AGV plate fixation resulted in high rates of complications related to plate or tube movement, the need for further intervention, and AGV removal. Therefore, we cannot recommend this surgical technique.

Therefore, we cannot recommend this surgical technique.Minimally invasive glaucoma surgeries have become increasingly popular in recent years, with the iStent Inject trabecular micro-bypass device (Glaukos, Laguna Hills, CA) being a well-tolerated treatment option for mild to moderate glaucoma, available for placement at the time of cataract surgery. While there have been reports of hyphema in the immediate postoperative period, there is little information available regarding etiology and management of delayed-onset, recurrent hyphema following iStent Inject placement. We present a case of recurrent hyphema occurring after iStent Inject placement and describe successful management with surgical removal of the device. Since we observed a reflux of heme originating from the site of stent placement into the anterior chamber intraoperatively when the intraocular pressure was lowered, we hypothesize that placement of the device into a collector channel allowed for influx of heme when the intraocular pressure dropped below episcleral venous pressure.The study was a prospective observational study comparing semiautomated to manual quantitative ultrasound biomicroscopy image analysis among 82 images from 41 eyes of 32 subjects (21 controls and 11 glaucoma) enrolled in the Pediatric Anterior Segment Imaging Innovation Study. Intraclass correlation coefficients and correlation coefficients were >0.8 for all parameters, and comparison of respective analysis speed was 7 times faster for the semiautomated method compared with manual image quantification.
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.

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. As many people now have these devices implanted in their eyes, the issue of their compatibility with MRI in terms of safety and interference with interpretation of these studies commonly arises. The purpose of this study is to evaluate the safety of 3T MRI scans in eyes that have undergone iStent implantation and to assess the interference of the implant to the scan interpretation.

An ex vivo model of sheep eye with an iStent and proximately placed heat detector probe was used to study changes in the temperature during MRI 3T scan. The study included 2 fresh eyes with preserved extraocular muscles and orbital fat tissue placed in the orbital cavity of a human skull. Each eye with orbital content was scanned with a 3T MRI machine.

No displacement of the implant was observed during MRI scanning. The heat detector showed mild temperature elevation during the first minutes of the scan from 14.6 to 16.5°C. The iStent was best visualized in T2 turbo spin echo sequences and showed no significant artifacts.

iStent implants did not move during the MRI scan, showed minimal interaction with the magnetic field in terms of heating and image distortion. These interactions were not strong enough to present a substantial risk to patients with this implant undergoing an MRI scan.

Standalone trabecular micro-bypass glaucoma surgery with the iStent devices is associated with clinically relevant reductions in intraocular pressure (IOP) sustained over a reasonably long-term while simultaneously reducing medication burden and a relatively favorable safety profile.

While there is a relatively large body of evidence supporting the implantation of the iStent trabecular micro-bypass devices during phacoemulsification in patients with open-angle glaucoma (OAG), its efficacy as a standalone procedure has been less widely reported. The aims of this study were to systematically identify and quantitatively evaluate the efficacy of iStent devices (iStent and iStent inject) when performed independently of cataract surgery in patients with OAG.

A systematic review of the literature was undertaken in August 2019 to identify studies of standalone trabecular micro-bypass glaucoma surgery with iStent devices in patients with OAG. All randomized trials were considered and nonrandomized studies that included at least 6 months of follow-up or more than 10 eyes.
