Abstract
A confocal scanning diode laser ophthalmoscope (Retina Tomograph, Heidelberg Engineering, GmbH, Heidelberg, F.R.G.) was used to examine the optic nerve head in both normal healthy (n = 10) and glaucomatous (n = 10) eyes. An image series was obtained from 32 transverse optical sections taken at consecutive height planes (50-80 μm each) over a 1.5-2.5-mm scan depth. Each image was then analyzed to create a topographic map containing 256 × 256 pixels (65,536 pixels) with a field of view of 10°. Images were obtained through undilated pupils. Reproducibility was 30.1 ± 7.0 and 31.8 ± 10.6 μm in normal and glaucomatous eyes, respectively. The instrument provides highly reproducible topographic data of the optic nerve head in patients with undilated pupils.
