EYEGROUND OBSERVATION DEVICE

Title:

EYEGROUND OBSERVATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/125746

Kind Code:

A1

Abstract:

Disclosed is an eyeground observation device capable of capturing an image of a vision acuity measurement region of the eyeground. A control unit (210) of the eyeground observation device (1) changes the relative display positions of a Landolt ring (T) displayed by an LCD (39) and a fixation target (V) on the basis of a scan region (R), thereby changes the projection region of the Landolt ring (T) on the eyeground (Ef), and thereby causes the scan region (R) scanned with a signal light (LS) and the projection region of the Landolt ring (T) to overlap with each other. In this state, the eyeground observation device (1) performs vision acuity measurement and OCT measurement, determines the value of the vision acuity in the region of interest of the eyeground (Ef), and creates a tomogram of the eyeground (Ef) in the scan region (R). The control unit (210) associates the value of the vision acuity in the region of interest with the tomogram corresponding to the scan line nearest to the vision acuity measurement position, stores the value of the vision acuity and the tomogram in a storage unit (212), and allows the display device (3) to display the value of the vision acuity and the tomogram.
