| Abstract;We evaluated glaucoma's prevalence, estimated rate of prevalence, and frequency doubling technology (FDT) performance in the health-check program at Nadogaya Hospital from January to December 2002. Each person was measured for visual acuity and intraocular pressure (IOP), and underwent fundus photography and visual field testing with FDT. The initial screening result was considered glaucoma positive when IOP exceeded 21 mmHg, the fundus photograph showed glaucomatous cup-to-disc ratio or retinal nerve fiber layer defect; or FDT detected at least one abnormal point. Recall assessment comprised several examinations. Of 130 individuals with suspected glaucoma (7.39%), 31 were diagnosed with glaucoma after recall assessment and telephone survey. Glaucoma prevalence and estimated rate of prevalence were 1.76 % and 3.27 %, respectively. The positive prediction rate for detecting definitive glaucoma in visual field abnormalities using FDT was 45.7%. It should be noted that FDT is useful in screening for glaucomatous visual field defect. (author abst.) |
