Purpose: To compare computerized stereoscopic optic disc photography, plane optic disc photography, and OCT in ONH analysis and predictability of glaucomatous field defects.
Methods: A total of 99 eyes of 50 patients were studied from December 2004 to February 2005. Complete ophthalmic examinations were performed which included computerized stereoscopic optic disc photography, plane optic disc photography, OCT, and a visual field test.
Results: The three methods analyzed in this study were largely correlated with each other. However, the horizontal cup-disc ratio using OCT differed from the other methods. The most valuable data was vertical CDR estimation using computerized stereoscopic optic disc photography. The sensitivity and specificity of computerized stereoscopic optic disc photography on a glaucomatous field defect using multivariate analysis were 80% and 100%, respectively. The hit ratios of computerized stereoscopic optic disc photography, plane optic disc photography, and OCT were 90.9, 81.6 and 60.7, respectively.
Conclusions: ONH analysis using computerized stereoscopic optic disc photography may be a benefit in the diagnosis and follow-up of glaucoma patients. It is thought that easy accessibility and convenient storage of computerized photography will be useful for the detection of glaucomatous visual field defects.
