GLAUCOMA SCREENING WITH OCULOKINETIC PERIMETRY IN GENERAL-PRACTICE - IS ITS SPECIFICITY ACCEPTABLE

The main aim of the study was to estimate the specificity of oculokine tic perimetry (OKP) for glaucoma case-finding in general practice. The visual fields of 185 consecutive patients aged 40 years or more were screened with OKP in one general practice, Test specificity was 94%, T he OKP test was abnormal in 17 patients, At follow-up 6 of these patie nts had glaucoma or were glaucoma suspects, Three of the remaining 11 patients had cataract. Eight OKP-positive patients had no eye disease. In 96 of the patients results of OKP were compared with Bjerrum campi metry, which revealed one possibly false-negative OKP test, Ten patien ts with previously diagnosed glaucoma were also examined with OKP, All 10 patients were identified by the OKP test, In 80 of the patients OK P was performed twice, supervised by two different observers, The prop ortion of agreement for normal tests was very high: 0.96 (95% CI: 0.91 -1.0), The proportion of agreement for abnormal tests was 0.79 (95% CI : 0.57-1.0), The OKP test may be useful in glaucoma case-finding in ge neral practice, However, the proportion of false-positive tests seems to be too high for OKP to be used alone in mass screening.
