Investing in a healthy lifestyle strategy: is it worth it?

Objectives: In Quebec, various actors fund activities aimed at increasing physical activity, improving eating habits and reducing smoking. The objective was to evaluate how effective does the healthy lifestyle habits promotion (HLHP) strategy need to be to make to offset its costs.

Methods: First, we built the logic model of the HLHP strategy.

Screening for glaucoma using GDx-VCC in a population with ≥1 risk factors.

Objective: To estimate the diagnostic accuracy of the GDx-VCC for glaucoma screening in a population with ≥1 risk factors for glaucoma.

Design: Cross-sectional evaluation of a diagnostic test for screening.

Participants: Two hundred forty-seven community-based volunteer participants with risk factors for glaucoma.

Screening for glaucoma in high-risk populations using optical coherence tomography.

Objective: To estimate the diagnostic accuracy of Stratus optical coherence tomography (OCT) for glaucoma screening in high-risk populations.

Design: Cross-sectional evaluation of a diagnostic test for screening.

Participants: Three hundred thirty-three community-based volunteer participants with risk factors for glaucoma.

Validity of screening for glaucomatous optic nerve damage using confocal scanning laser ophthalmoscopy (Heidelberg Retina Tomograph II) in high-risk populations: a pilot study.

Purpose: To evaluate whether confocal scanning laser ophthalmoscopy (Heidelberg Retina Tomograph II [HRT II], Heidelberg Engineering, Heidelberg, Germany) is a valid tool for the detection of glaucomatous optic nerve damage.

Design: Observational, cross-sectional, nonconsecutive study in Montreal, Canada.

Participants: Three hundred three nonconsecutive, high-risk persons were enrolled during a 6-month period.

The effect of compression on clinical diagnosis of glaucoma based on non-analyzed confocal scanning laser ophthalmoscopy images.

Background And Objective: To evaluate the effect of different image compression formats of non-analyzed Heidelberg Retina Tomography (HRT; Heidelberg Engineering, Heidelberg, Germany) images on the diagnosis of glaucoma by ophthalmologists.

Materials And Methods: Thirty-three topographic and reflectance images taken with the HRT representing different levels of disease were transformed using nine different compression formats. Three independent ophthalmologists, masked as to contour line and stereometric parameters, classified the original and compressed HRT images as normal, suspected glaucoma, or glaucoma, and Kappa agreement coefficients were calculated.
