title: [Importance of standardized photos for planimetry].
abstract: In a series of 30 patients we compared the optic disc measurements. Disc photographs were either taken centric or excentric. Pictures with excentric discs showed significantly smaller measurements. However, the C/D-ratio demonstrated a good correlation (r = 0.95). For follow-up studies even not standardized photos can be useful, especially if the same examinator makes all the measurements.
