Economic burden and loss of quality of life from dry eye disease in Canada.

Objective: To describe the direct and indirect cost estimates of dry eye disease (DED), stratified by disease severity, and the impact of DED on quality of life (QoL) in Canadian patients.

Methods And Analysis: A prospective, multicentre, observational, cross-sectional study was conducted at six sites across Canada. Eligible patients completed a 20 min survey on demography, general health, disease severity, QoL and direct (resource utilisation and out-of-pocket expenses for the past 3-24 months) and indirect costs (absenteeism and presenteeism based on Work Productivity and Activity Impairment questionnaire responses).

Infrared imaging of meibomian glands and evaluation of the lipid layer in Sjögren's syndrome patients and nondry eye controls.

Purpose: The purpose of this study was to evaluate meibomian gland dropout and lipid layer thickness (LLT) in patients with and without Sjögren's syndrome dry eye (SS).

Methods: We recruited 11 participants with SS (males/females [M/F], 1:10; mean age = 56.0 ± 9.

Gonioscopy: evaluation of the anterior chamber angle. Part II.

Gonioscopy is the standard procedure for examination of the anterior chamber angle, and is an invaluable technique in primary eye care. The clinician must practise the technique and observe many angles, because enormous but often subtle variation can be seen by the experienced observer in both normal and abnormal angles. Gonioscopy is essential to master, not only for the assessment of patients' risk for angle closure following dilation, but also in the diagnosis and subsequent management of the acute and chronic glaucomas and many other anterior segment disorders.
