Developing standards for the development of glaucoma virtual clinics using a modified Delphi approach.

Purpose: To obtain consensus opinion for the development of a standards framework for the development and implementation of virtual clinics for glaucoma monitoring in the UK using a modified Delphi methodology.

Methods: A modified Delphi technique was used that involved sampling members of the UK Glaucoma and Eire Society (UKEGS). The first round scored the strength of agreement to a series of standards statements using a 9-point Likert scale.

Patient perspectives when switching from Cosopt(®) (dorzolamide-timolol) to Azarga™ (brinzolamide-timolol) for glaucoma requiring multiple drug therapy.

Background: This study aimed to determine the impact of switching patients requiring multiple drug treatment from the dorzolamide-timolol fixed combination to the brinzolamide-timolol fixed combination and potential effects on tolerability and compliance.

Methods: Patients were switched from dorzolamide-timolol to brinzolamide-timolol and questioned within a period of 4-26 weeks. Questions were asked to confirm if a specific side effect had been experienced, and then a numerical comparison between the two types of eye drop was made.
