Glaucoma in optometric practice: a survey of optometrists

Abstract

SummaryAims/background: With the ageing population, numbers of glaucoma patients are an increasing problem in ophthalmic outpatient clinics. A postal questionnaire survey was carried out in Northern Ireland with the aim of finding out how well placed optometrists are to become involved in the monitoring of glaucoma.Results: Of the 171 practices surveyed, 68% of the senior practitioners responded. One practice was without a tonometer and one practice was without visual field instrumentation. Age criteria were used by 95% of practitioners for measuring intraocular pressure (IOP) and 82% used appropriate selection criteria for visual field testing. An IOP of 25 or 26 mmHg was used by 45% of practitioners as the level for referral if there are no risk factors; 89% would refer at any level if a visual field defect and disc cupping were present.Conclusion: The results confirm that the majority of optometrists are well equipped for the screening of glaucoma. However a significant investment in training and equipment would be required if any sort of shared care scheme were to be introduced.
