This study's goal was to determine the diagnostic accuracy of FDT and MDT for visual field defects and glaucoma.

Diagnostic accuracy of an iPad application for detection of visual field defects.

Background/objectives: Tablet-based perimetry could be used to test for glaucomatous visual field defects in settings without easy access to perimeters, although few studies have assessed diagnostic accuracy of tablet-based tests. The goal of this study was to determine the diagnostic accuracy of iPad perimetry using the visualFields Easy application.

Subjects/methods: This was a prospective, cross-sectional study of patients undergoing their first Humphrey Field Analyser (HFA) visual field test at a glaucoma clinic in India.

Repeatability of Corneal Hysteresis Measurements in Glaucoma Patients During Routine Follow Up and After Cataract Surgery.

Accuracy of autorefraction in an adult Indian population.

Purpose: Autorefractors allow non-specialists to quickly assess refractive error, and thus could be a useful component of large-scale vision screening programs. In order to better characterize the role of autorefraction for public health outreach programs in resource-limited settings, the diagnostic accuracy of two autorefractors was assessed relative to subjective refraction in an adult Indian population.

Methods: An optometrist refracted a series of patients aged ≥50 years at an eye clinic in Bangalore, India using the Nidek ARK-900 autorefractor first, followed by the 3nethra Royal autorefractor, and then subjective refraction.

Cutaneous melanin and glaucoma: a case control study.

: Previous studies have used subjective assessments to implicate darker skin color as a risk factor for glaucoma. This study used objective measurements to determine whether skin melanin is a risk factor for glaucoma. In a case-control study conducted at a tertiary eye hospital in Nepal, patients aged 40 years or older from the glaucoma clinic were enrolled as cases and age-matched patients without glaucoma from other clinics at the eye hospital were enrolled as controls.

Design: Retrospective chart review.

The Relationship Between Melanin and Glaucoma: A Case-control Study.

Unlabelled: PRéCIS:: In a case-control study, skin pigmentation was not statistically significantly different when comparing glaucoma patients to those without glaucoma.

Purpose: Darker skin color has been implicated as a risk factor for glaucoma based on previous studies' subjective assessments of skin pigmentation. This study used objective measurements to determine whether cutaneous pigmentation is a risk factor for glaucoma.

Trends in Authorship of Original Scientific Articles in Journal of Glaucoma: An Analysis of 25 Years Since the Initiation of the Journal.

Accuracy of computer-assisted vertical cup-to-disk ratio grading for glaucoma screening.

Purpose: Glaucoma screening can be performed by assessing the vertical-cup-to-disk ratio (VCDR) of the optic nerve head from fundus photography, but VCDR grading is inherently subjective. This study investigated whether computer software could improve the accuracy and repeatability of VCDR assessment.

Methods: In this cross-sectional diagnostic accuracy study, 5 ophthalmologists independently assessed the VCDR from a set of 200 optic disk images, with the median grade used as the reference standard for subsequent analyses.

Reproducibility of 5 Methods of Ocular Tonometry.

Purpose: To evaluate the agreement between Goldmann applanation tonometry (GAT; Haag-Streit, Bern, Switzerland) and several portable tonometers that could be used for glaucoma screening programs.

Design: Evaluation of a diagnostic test.

Participants: Three hundred twenty-one eyes of 168 participants seeking treatment at the glaucoma clinic of a tertiary eye hospital in India.

Ophthalmic Timolol Hallucinations: A Case Series and Review of the Literature.

Purpose: Systemic absorption and central nervous system (CNS) penetration of timolol drops are a well-studied phenomenon, resulting in common side effects such as bradycardia, bronchospasm, fatigue, and confusion. More serious CNS side effects, such as psychosis and depression, however, are rarely attributed to eye drops. We report a case series in which patients developed visual hallucinations secondary to topical ocular timolol use.
