Abstract

Abstract: : Purpose: To evaluate the usefulness of the NMFu-Camera and the FDP for detecting glaucoma in a general population. Methods: The population of 3 belgian cities was invited by advertisement in newspaper and TV to present for glaucoma screening.The IOP was measured with the non-contact pneumo-tonometer(NCT) followed by an applanation tonometry(AT)if the NCT-IOP was ≷ or equal to 17 mmHg.The visual field was screened with the FDP(C-20-5) and optic disc photographs (ODP's) were taken with the NMFu-Camera(Canon CR6-45NM).FDP was considered abnormal if at least one defective point was found. The ODP's were graded as normal or glaucomatous by consensus of 3 glaucoma specialists. Treated patients were excluded from the analysis. Results: 1800 subjects were examined and 1684 included in the study.The mean age was 63.5 +-10.8 years.Six percent had AT-IOP measurement ≷21 mmHg. 97.6% of the ODP's could be interpreted.Glaucomatous optic discs were detected in 3.7% of the subjects.FDP was abnormal in one eye in 19% and in both eyes in 23% of the subjects.The sensitivity and specificity of FDP in detecting the eyes with glaucomatous optic discs were 57% and 69% respectively. Conclusion: The non-mydriatic fundus Camera is a useful method to screen for glaucoma.FDP in screening strategy is not sensitive enough when the cut-off value is set at one defective test location.
