PURPOSE: To test the hypothesis whether semi-automated kinetic perimetry (SKP) provides additional information to static automated perimetry (SAP) in the assessment of the remaining visual field in end-stage glaucoma, as defined by disc appearance (cup-to-disc ratio worse than 0.9) and SAP criteria (MD worse than 20 dB). METHODS: Fifty eyes of 44 patients presenting with end-stage glaucoma were examined first with SAP within the central 30° using stimulus size III, followed by SKP within 90° using test targets III4e and V4e. RESULTS: Overall, SKP provided additional information over SAP in more than half (54%) of the cases. In 16 instances (32%), SKP revealed visual field island beyond 30° that was undetected by SAP. In eight cases (16%), SKP showed both a central island and peripheral island of visual field. In three cases (6%) altitudinal scotomatous loss was found using SKP, but not in SAP. In 23 cases (46%) the central visual field island was defined both with SAP and SKP. The mean examination duration was 4 min for SAP and 9 min for SKP. CONCLUSIONS: In clinical practice, SKP with III4e and V4e test targets provides more information than 30° SAP regarding the remaining peripheral VF in patients with end-stage glaucoma; however, a longer test time is required for SKP.
