Outcomes of shunt tube coverage with glycerol preserved cornea versus pericardium.

Pericardium is a biomaterial widely used for covering the outflow tubes of glaucoma drainage devices. Recently, glycerol preserved cornea has been introduced as an alternative that offers durability and improved cosmesis because of its clarity. We retrospectively reviewed 262 patients in the University of Alabama Birmingham Glaucoma Service who underwent shunt procedures using either cornea tissue or pericardium to cover the tube.

Visual field defects and the risk of motor vehicle collisions among patients with glaucoma.

Purpose: To evaluate the association between visual field defects in the central 24 degrees field and the risk of motor vehicle collisions (MVCs) among patients with glaucoma.

Methods: A nested case-control study was conducted in patients with glaucoma aged 55 or more. Cases were patients who were involved in a police-reported motor vehicle collision (MVC) between January 1994 and June 2000; controls were those who had not experienced an MVC at the time of their selection.

Is glaucoma associated with motor vehicle collision involvement and driving avoidance?

Purpose: To evaluate the association between the diagnosis of glaucoma and motor vehicle collision (MVC) involvement and driving avoidance in drivers aged > or =50 years.

Methods: Two groups of patients, one with glaucoma and one without, were identified in three university-affiliated eye care practices. Demographic, clinical, and driving characteristics were obtained by chart abstractions and a patient survey.
