· Background. The assessment of the cup of the optic disc in follow-up of glaucomatous optic nerve heads depends on the variability of the cup area over time. We examined the variability of topographic measurements depending on scan focus settings and evaluated the long-term fluctuations of the normalised rim/disc area ratio quotient of normal subjects for 1 year. · Methods. Part 1. Evaluation of the influence of scan focus and corneal curvature on the number of pixels per millimetre in one… CONTINUE READING
