Costing a community based screening programme for the detection of glaucoma.

The cost of detecting a case of glaucoma in a community based screening programme was calculated using data from a pilot study on a population aged 50 and over. The cost per screen was estimated at 3.35 pounds with a total cost of 311 pounds per case detected. These estimates include the cost of both the algorithmically based screening programme and the hospital assessment of true and false positives. These costs are considered to compare favourably with the potential costs incurred by paying optometrists to screen high risk groups whilst providing the opportunity to detect over twice the number of cases of occult glaucoma.
