Abstract

An ophthalmologic photographing apparatus includes: an optical coherence system for obtaining a tomographic image of an examinee's eye, having an optical scanner for scanning the eye with measurement light and a detector for detecting an interference signal of the light and reference light; an observing optical system for acquiring a front image of the eye; a scan controller for controlling the optical scanner to scan with the light different transverse positions set on the image, and acquire first interference signals at the positions; a display controller for displaying on a monitor an image created in response to the first interference signal; and an image recapture setting unit for setting a rephotographing transverse position in response to an operation signal from an operating unit for the image on the monitor. The scan controller scans the eye with the light at the rephotographing transverse position, and acquires a second interference signal.

First claim

What is claimed is:

1. An ophthalmologic photographing apparatus comprising:
