The Heidelberg retina tomograph is a confocal scanning laser ophthalmoscope that permits recording of topographic information related to the optic nerve and retina. We studied the reproducibility of the topographic parameters obtained by recording five times sequentially the images obtained from one eye of five healthy people and five glaucoma patients. The reproducibility coefficients ranged from 60.5 to 99.4%. The results indicate that, for the parameters examined, the instrument has a high level of reproducibility.
