Purpose: To investigate the effect of change in body mass index (BMI) on intraocular pressure (IOP) in a large cohort of apparently healthy volunteers who underwent an annual comprehensive screening examinations.

Methods: This study included individuals who were enrolled in the Tel Aviv Medical Center Inflammation Survey (TAMCIS) and had IOP and BMI measurements at their baseline and follow up visits. Relationships between BMI and IOP and the effect of change in BMI on IOP were investigated.

Unlabelled: To report clinical outcomes following ocular injury from foam dart (nerf) blasters - a spring-loaded toy guns that fire foam-coated darts or bullets at a relatively low velocity. These guns gained popularity in recent years among children and adolescents. Eleven patients with ocular injuries from foam dart blasters were included in this retrospective, single-center study.

Aim: To report short-term outcomes of mitomycin C-augmented excisional bleb revision with capsulectomy (ERC) after Ahmed glaucoma valve (AGV) failure.

Methods: Patients who underwent ERC procedures between January 2017 and December 2019 with a minimum follow-up of 6mo were evaluated retrospectively for indications of AGV and AGV implantation to ERC interval. The number of anti-glaucoma medications (AGMs), intraocular pressure (IOP) and best corrected visual acuity (BCVA) were recorded at baseline, 1, 7, 30, 90, and 180d.

Glaucoma, a progressive optic neuropathy characterized by retinal ganglion cell degeneration and visual field loss, is the leading cause of irreversible blindness worldwide. Intraocular pressure (IOP) is presently the only modifiable risk factor demonstrated to slow or halt disease progression; however, glaucomatous damage persists in almost 50% of patients despite significant IOP reduction. Many studies have investigated the non-IOP-related risk factors that contribute to glaucoma progression as well as interventions that can prevent or delay glaucomatous neurodegeneration and preserve vision throughout life, independently of IOP.

Purpose: The purpose of this study was to assess patient interest and willingness to pay (WTP) for teleophthalmology services, whose benefits include improved healthcare access and potential cost savings.

Patients And Methods: Cross-sectional study of 215 patients attending a single tertiary center to assess their interest in teleophthalmology. Comparisons between those interested and those not interested were conducted; logistic regression was used to evaluate the effect of price on interest.

Purpose: To investigate the effects of mental stress stimulus on intraocular pressure (IOP) measurement and visual field (VF) testing.

Methods: Patients with open angle glaucoma underwent a baseline IOP measurement and VF testing. Afterwards, they completed a computerized mental stress test (Stroop test) which is a known standardized method to induce mental stress.

Introduction: Appointment nonadherence is common among people with glaucoma, making it difficult for eye care providers to monitor glaucoma progression. Our objective was to determine whether the use of patient navigators, in conjunction with social worker support, could increase adherence to recommended follow-up eye appointments.

Methods: A randomized, controlled trial evaluated the effectiveness of an intervention that used patient navigators and social workers to improve patient adherence to follow-up eye care compared with usual care.

The purpose of this study was to investigate the feasibility and effectiveness of an innovative telemedicine community-based intervention to increase detection of previously undiagnosed ocular diseases in high-risk populations in Israel. A team comprising an ocular technician, a project manager, and a driver was sent to underserved areas in Israel. Patient demographics, ocular, and medical information were recorded.

Glaucoma is characterized by retinal ganglion cell loss that can lead to permanent visual loss. Current clinical management practice assumes that glaucomatous visual loss is irreversible; however, there is increasing evidence that permanent vision loss and cell death are preceded by reversible functional and structural changes. We propose that these changes should be considered by glaucoma specialists when treating their patients.

Background: Diabetic retinopathy (DR) is a significant global public health and economic burden. DR accounts for approximately 15-17% of all cases of total blindness in the USA and Europe. Telemedicine is a new intervention for DR screening, however, there is not enough evidence to support its cost-effectiveness.

Purpose: To evaluate the repeatability of the steady-state pattern electroretinogram (PERG) and full-field flicker electroretinogram (Flicker ERG) protocols, delivered by the office-based Neuro Optic Vision Assessment (NOVA)™ testing platform, in healthy subjects.

Methods: Healthy individuals underwent PERG (16° and 24°) and Flicker ERG [fixed luminance (FL) and multi-luminance (ML)] testing protocols. Test-retest repeatability of protocols was calculated using intra-class correlation coefficients (ICC).

: To investigate: 1) the impact of reduced contrast sensitivity (CS) in specific areas of vision on subjective assessment of vision-related quality of life (VRQoL) and objective performance-based measures in patients with primary open-angle, primary angle-closure, and pseudoexfoliation glaucoma; and 2) correlations between measurements of contrast sensitivity (CS) in specific areas of vision and visual field (VF) tests. : The Spaeth/Richman Contrast Sensitivity Test (SPARCS) measured CS in the inferior, superior, and central areas, while the Pelli-Robson test measured central CS. Visual fields were tested in participants using standard-automated perimetry.

Objective: To determine the test-retest repeatability of minimum rim width and retinal nerve fibre layer thickness measurements obtained by spectral-domain optical coherence tomography using the Anatomic Positioning System protocol in glaucoma patients and controls. Also, to assess the ability of the minimum rim width and retinal nerve fibre layer thickness to diagnose glaucoma in 2 circular peripapillary locations.

Methods: Spectral domain optical coherence tomography scans of the optic nerve head were obtained twice during the same visit using the Anatomic Positioning System eye-tracking protocol.

Aim: To validate the ability of the Heidelberg Edge Perimeter (HEP) in detecting glaucomatous visual field (VF) defects compared to the Octopus Visual Field (OVF) Analyzer and to determine the test-retest repeatability of both modalities.

Methods: This prospective, cross-sectional study was conducted at Wills Eye Hospital, Philadelphia, PA. Glaucoma subjects and unaffected controls underwent VF testing using HEP standard automated perimetry (SAP) III 30-2 Adaptive Staircase Thresholding Algorithm (ASTA) FAST protocol and OVF G-TOP white-on-white strategy.

Precis: Intraocular pressure (IOP) measurements, when used during telemedicine eye screening alongside nonmydriatic fundus photography, were shown to improve the likelihood of accurate glaucoma and glaucoma-related diagnoses at the follow-up eye examination.

Purpose: To determine if IOP measurements, used as an adjunct to nonmydriatic fundus photography, are useful in glaucoma telemedicine screening.

Materials And Methods: A total of 902 high-risk individuals were screened for glaucoma at 7 primary care practices and 4 Federally Qualified Health Centers using telemedicine.

Aims: To evaluate agreement between ocular findings of a telemedicine eye screening (visit 1) with diagnoses of a comprehensive eye examination (visit 2).

Methods: A primary care practice (PCP)-based telemedicine screening programme incorporating fundus photography, intraocular pressure (IOP) and clinical information was conducted. Eligible individuals were African American, Hispanic/Latino or Asian over the age of 40; Caucasian individuals over age 65; and adults of any ethnicity over age 40 with a family history of glaucoma or diabetes.
