OCT Segmentation Errors with Bruch's Membrane Opening-Minimum Rim Width as Compared with Retinal Nerve Fiber Layer Thickness.

Objective: To compare the magnitude and location of automated segmentation errors of the Bruch's membrane opening-minimum rim width (BMO-MRW) and retinal nerve fiber layer thickness (RNFLT).

Design: Cross-sectional study.

Participants: We included 162 glaucoma suspect or open-angle glaucoma eyes from 162 participants.

Patients with Low Vision Struggle with Placing Eye Drops and Benefit from an Eye Drop Aid.

Purpose: To evaluate eye drop self-administration in a low-vision patient population and test whether a nose-pivoted drop delivery device (NPDD, GentleDrop) can improve eye drop delivery in these patients.

Design: Repeated-measures case series.

Participants: Thirty subjects (58 eyes) with low vision, defined as best-corrected visual acuity worse than 20/60 or visual field worse than 20° in the better-seeing eye.

Eye Drop Adherence With an Eye Drop Bottle Cap Monitor.

Prcis: An eye drop bottle cap monitor with audio and visual alarms measured eye drop adherence in 50 subjects with glaucoma. Baseline adherence rates were too high to test if the alarms could improve adherence.

Purpose: To determine if an eye drop bottle cap monitor can measure and improve adherence.

Geospatial analysis of blindness within rural and urban counties.

Purpose: To determine the associations of blindness within rural and urban counties using a registry of blind persons and geospatial analytics.

Methods: We used the Oregon Commission for the Blind registry to determine the number of persons who are legally blind, as well as licensure data to determine the density of eye care providers (optometrists and ophthalmologists) within each county of the State of Oregon. We used geospatial statistics, analysis of variance, and logistic regression to determine the explanatory variables associated with blindness within counties.

Intraocular Pressure and Medication Burden With Cataract Surgery Alone, or Cataract Surgery Combined With Trabecular Bypass or Goniotomy.

Prcis: When compared with cataract surgery in glaucoma patients, trabecular micro-bypass and goniotomy resulted in a large decrease in the incidence of intraocular pressure (IOP) spikes, a modest effect on IOP, and a minimal effect on medication burden.

Purpose: To compare changes in IOP and ocular hypotensive medications in 3 surgical cohorts: cataract surgery, cataract surgery with trabecular micro-bypass (cataract/trabecular), and cataract surgery with goniotomy (cataract/goniotomy).

Materials And Methods: We included 138 eyes diagnosed with open-angle glaucoma: (1) 84 eyes with cataract surgery alone, (2) 25 eyes with cataract/trabecular surgery, and (3) 29 eyes with cataract/goniotomy surgery.

MicroPulse Transscleral Laser Therapy - Fluence May Explain Variability in Clinical Outcomes: A Literature Review and Analysis.

Since the first peer-reviewed publication on MicroPulse Transscleral Laser Therapy (MP-TLT) in 2010, authors worldwide have used a wide range of treatment parameter combinations with varying clinical efficacy in terms of the magnitude of intraocular pressure reduction, success rate, durability, and safety profile. This has made it difficult to determine the proper parameters necessary to optimize efficacy and safety, and has made comparison of results from one investigation to another difficult. The first goal of this paper is to explain and highlight the impact of the choices of exposure time and the number of sweeps per hemisphere in terms of "sweep velocity" on energy delivery to the eye.

Novel Eye Drop Delivery Aid Improves Outcomes and Satisfaction.

Purpose: To compare a nose-pivoted drop delivery device (NPDD) with traditional eye drop delivery in glaucoma subjects.

Design: Repeated-measures case series.

Participants: Fifty glaucoma subjects (100 eyes) who reported difficulty self-administering eye drops.

Predicting Adherence With the Glaucoma Treatment Compliance Assessment Tool.

Unlabelled: PRéCIS:: Univariate and multivariable models using the Glaucoma Treatment Compliance Assessment Tool (GTCAT) statements identified multiple, patient-specific factors associated with adherence that could be used to inform personalized interventions to optimize glaucoma adherence.

Purpose: The purpose of this study was to determine the health behavior factors related to glaucoma adherence in patients with self-reported poor adherence.

Methods: A research coordinator used the Chang Adherence Measure and the Morisky Medication Adherence Scale to identify subjects with poor self-reported glaucoma medication adherence and enrolled them in a 3-month study to electronically monitor medication adherence.

Effect of Trabeculectomy on OCT Measurements of the Optic Nerve Head Neuroretinal Rim Tissue.

Purpose: Ophthalmologists commonly perform glaucoma surgery to treat progressive glaucoma. Few studies have examined the stability of OCT neuroretinal rim parameters after glaucoma surgery for ongoing detection of glaucoma progression.

Design: Longitudinal cohort study.

Update on Micropulse Transscleral Cyclophotocoagulation.

Micropulse transscleral cyclophotocoagulation is a promising and relatively new technique that uses repetitive micropulses of diode laser energy, delivered with the Cyclo G6 Glaucoma Laser System (Iridex Corporation), in an off-and-on cyclical manner. This review article provides an update on the latest data available for this technique, including a discussion of the aspects in which there is still limited data, such as the precise mechanism of action, the ideal laser parameters based on total energy levels, as well as an overview of other potentially relevant variables that may be playing an important role in outcomes.

Micropulse Transscleral Cyclophotocoagulation: A Hypothesis for the Ideal Parameters.

MicroPulse transscleral cyclophotocoagulation (IRIDEX Corp., Mountain View, CA) is a novel technique that uses repetitive micropulses of active diode laser (On cycles) interspersed with resting intervals (Off cycles). It has been proposed that the OFF cycles allow thermal dissipation and, therefore, reduce collateral damage.
