Abstract
We evaluated the sensitivity and specificity of Frequency doubling perimetry[FDP]with fourty-nine normal subjects and twenty-six patients of early glaucomatous field change. We regarded Humphrey field analyzer[HFA]30-2 GHT as gold standard. 'True positive 'was regarded as 'outside normal limit 'or P-value of MD or PSD below 0.05 at HFA, 'abnormal 'at FDP P-value of MD or PSD below 0.05. MD of early glaucoma was -5.4 decibel at HFA and -6.61 decibel at FDP, Sensitivity of early glaucoma was 96.1%with FDP and 84.6%with HFA;specificity, 89.7%with FDP and 83.6%with HFA. We could confirm FDP threshold test showed good sensitivity in detecting early glaucoma. Especially, use of PSD increased efficiency of the test.
Key Words: Early glaucoma;FDP;HFA
