Abstract

Purpose: This study was designed to assess the repeatability of the standard analysis of images taken with the Nidek EAS-1000 anterior segment analysis system (Nidek Co. Ltd, Japan). Methods: Participants in a large clinical trial (the vitamin E, cataract and age-related maculopathy study) were asked to undergo two independent examinations to assess the repeatability of primary outcome measures. After pupil dilatation to at least 6.5 mm, 104 eyes were photographed using the retro-illumination method and the slit-beam method. Results: Intra-class correlation coefficients were: slit images, R = 0.982; retro-illumination images, R = 0.978. Conclusion: Repeatability of measurement of lens opacity from EAS-1000 images using automated standard analysis was high.
