The authors evaluated the possible interobserver differences in assessing the optic disc in 30 glaucomatous eyes recorded by a Heidelberg Retina Tomograph. The records were independently analyzed by two glaucoma specialists with regard to disc area, cup area, cup volume, rim volume, and maximum cup depth. There were close correlations between the findings of the two observers for all five parameters (coefficients of correlation, 0.72-1.00) with no significant interobserver differences (p<0.05). These findings show that reproducible interpretation of the disc margin is possible when performed by trained observers, even when the manipulation is performed manually.
