Purpose:To evaluate the optic disc by means of fundus photograph and Heidelberg Retina TomographⅡ(HRTⅡ). Cases and Methods:This study was made on 25 eyes of primary open-angle or normal-tension glaucoma. The fundus was photographed with a conventional fundus camera at the angle of 20 degrees. The color fundus photograph was then subjected to manual planimetry to delineate the border of disc cupping. The thus obtained rim area/disc area ratio(R/D ratio)was compared with the finding by HRTⅡ. Findings:The R/D ratio averaged 0.36±0.10 by fundus photograph and 0.40±0.15 by HRTⅡ. The difference was not significant(p=0.3). The R/D ratio was positively correlated with mean deviation(MD)of static visual field(p=0.002 for fundus photograph,p=0.001 for HRTⅡ). Conclusion:Evaluation of optic disc is possible either by planimetry of fundus photograph or HRTⅡ,as both methods result in essentially equal findings.
