Flicker perimetry (CFF) in patients with lens opacities--first report

PURPOSE: Comparison of standard W/W and CFF perimetry in patients with cataract and lens opacities. MATERIAL AND METHODS: Visual field was measured on Octopus 301 perimeter with option flicker perimetry. W/W and CFF perimetry (Program G1 in TOP strategy) was performed in 44 eyes with cataract and lens opacities. RESULTS: Defects in visual field with CFF perimetry were found in 24% of cases but with W/W perimetry in 100% of cases. CONCLUSIONS: Perimetry CFF is a new tool for early detection and follow up of visual field defects in patients with cataract and lens opacities.
