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. 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. GSK3368715 concentration 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.

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.
