Glaucoma progression detection with frequency doubling technology (FDT) compared to standard automated perimetry (SAP) in the Groningen Longitudinal Glaucoma Study.

Purpose: To determine the usefulness of frequency doubling perimetry (FDT) for progression detection in glaucoma, compared to standard automated perimetry (SAP).

Methods: Data were used from 150 eyes of 150 glaucoma patients from the Groningen Longitudinal Glaucoma Study. After baseline, SAP was performed approximately yearly; FDT every other year.

Factors that influence standard automated perimetry test results in glaucoma: test reliability, technician experience, time of day, and season.

Purpose: To determine the influence of several factors on standard automated perimetry test results in glaucoma.

Methods: Longitudinal Humphrey field analyzer 30-2 Swedish interactive threshold algorithm data from 160 eyes of 160 glaucoma patients were used. The influence of technician experience, time of day, and season on the mean deviation (MD) was determined by performing linear regression analysis of MD against time on a series of visual fields and subsequently performing a multiple linear regression analysis with the MD residuals as dependent variable and the factors mentioned above as independent variables.

Persistence, spatial distribution and implications for progression detection of blind parts of the visual field in glaucoma: a clinical cohort study.

Background: Visual field testing is an essential part of glaucoma care. It is hampered by variability related to the disease itself, response errors and fatigue. In glaucoma, blind parts of the visual field contribute to the diagnosis but--once established--not to progression detection; they only increase testing time.

Risk factors for visual field progression in the groningen longitudinal glaucoma study: a comparison of different statistical approaches.

Purpose: To identify risk factors for visual field progression in glaucoma and to compare different statistical approaches with this risk factor analysis.

Patients And Methods: We included 221 eyes of 221 patients. Progression was analyzed using Nonparametric Progression Analysis applied to Humphrey Field Analyzer data.

[Infectious endophthalmitis after cataract extraction, a serious complication].

Cataract extraction with lens implantation is the most used surgical procedure worldwide and is relatively safe. Nevertheless, this procedure carries the risk for infectious complications, since a foreign body is implanted in the eye to which bacteria that may cause endophthalmitis can adhere. Acute postoperative endophthalmitis is a potentially devastating disease that prompts immediate recognition and therapy, whereas chronic postoperative endophthalmitis is a low virulent, long-lasting infection that is hard to diagnose and for which the choice of treatment should be weighed carefully.

Glaucoma monitoring in a clinical setting: glaucoma progression analysis vs nonparametric progression analysis in the Groningen Longitudinal Glaucoma Study.

Objective: To compare prospectively 2 perimetric progression detection algorithms for glaucoma, the Early Manifest Glaucoma Trial algorithm (glaucoma progression analysis [GPA]) and a nonparametric algorithm applied to the mean deviation (MD) (nonparametric progression analysis [NPA]).

Methods: Patients with a reproducible glaucomatous visual field defect at baseline in at least 1 eye were followed up prospectively using perimetry (Humphrey field analyzer 30-2 Swedish interactive thresholding algorithm). Classifications by GPA and by NPA at the end of the follow-up period were compared.
