The analysis do not support the setting up of a formal glaucoma screening program in Quebec, both because of the high degree of uncertainty and because of the high cost such a programwould entail. However, there already exists a significant level of diagnostic activity leading to the early detection of high intraocular pressure or glaucoma. These should be maintained and restricted, the way they currently are, to the 65 to 79 age bracket. The screening tests should not be undertaken more than every three years.
