Objectives: To evaluate the usefulness of a glaucoma and intraocular hypertension screening strategy for new cases detected. To evaluate the acceptability of taking intra-ocular pressure (IOP) and the appearance of side effects. Design: Cross-sectional, descriptive study. Setting: An urban health centre and the ophthalmology clinic of its main hospital. Participants: A total of 2044 patients aged over 40, 63.5% women and 36.5% men, with a mean age of 61.23 (SD, 11.42). They were selected by consecutive sampling from patients who visited the health centre over a 9-month period. Subjects diagnosed with glaucoma, ocular hypertension (OH), conjunctivitis, or corneal pathology were excluded. Interventions: Taking of IOP with Tonopen XL in primary care. Subjects with IOP > or = 21 mm Hg were referred to ophthalmology. In these patients, IOP was measured with Goldmann, and patients with confirmed OH received ophthalmoscopy and campimetry. Main measurements: Percentage of subjects with glaucoma, suspected glaucoma, and OH confirmed in ophthalmology. Positive predictive value (PPV) for OH. Results: One hundred subjects with OH were detected (4.89%; 95% CI, 3.93%-5.85%), of whom 21 were diagnosed with glaucoma (1.04%; 95% CI, 0.57-1.49) and 10 with suspected glaucoma (0.49%; 95% CI, 0.16-0.82). The PPV for OH was 44.27%. The acceptability of the test was 98.09%. No patients presented with side-effects following the taking of their IOP. Conclusions: The strategy evaluated is useful in terms of the number of subjects with glaucoma and OH detected. The acceptability of taking IOP with Tonopen XL was high.
