Abstract

Although A-scan and B-scan images of ocular diseases are clinically important for differential diagnosis, much useful diagnostic information is not yet available through these procedures. However, wave spectral analysis by computer can gather much of the missing information, thereby providing material effective for diagnosis. Table 1 shows a diagram of the experimental conditions.
