Patent ID: 8622547

Claim:
A fundus observation apparatus comprising: a projection part that includes a display part to display a visual target for measuring vision, and projects, via a predetermined optical path, said displayed visual target for measuring vision to the fundus of an eye; a light source that outputs low-coherence light; an optical system that splits said output low-coherence light into signal light and reference light, generates interference light by superposing said signal light that has passed through said fundus via said predetermined optical path and said reference light that has passed through a reference optical path, and detects said interference light; a scanning part that scans said fundus with said signal light; a controlling part that overlaps the projection region of said visual target for measuring vision projected by said projection part and the scanning region of said signal light scanned by said scanning part each other; an image forming part that forms an image of said fundus based on the detection results of interference light generated by superposing said signal light with which said scanning region is scanned and said reference light; and a storage part that stores said formed image and a vision value measured using said visual target for measuring vision while correlating them with each other.
