PROBLEM TO BE SOLVED: To provide a microscope system for ophthalmology that can easily set an OCT scan range, eliminating demerits of a Galileo type microscope.SOLUTION: An illumination system of a microscope system for ophthalmology irradiates an illumination light onto an eye to be examined. A pair of light receiving systems include an objective lens and an image pickup device respectively in which objective optical axes are arranged in a non-parallel manner, and the return light of the illumination light irradiated onto the eye to be examined is guided to the respective image pickup devices through the respective objective lenses. An OCT system divides a light from an OCT light source into a measurement light and a reference light, irradiates the measurement light on to the eye to be examined from a direction different from the objective optical axes, and detects an interference light obtained by synthesizing the return light of the measurement light from the eye to be examined and the reference light. An optical scanner is used for scanning the eye to be examined with the measurement light. An image drawing part draws a scan range by the optical scanner on an image based on the output from the image pickup device of at least one of the pair of light receiving systems.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ガリレオ式顕微鏡のデメリットが無く、OCTスキャン範囲を容易に設定可能な眼科用顕微鏡システムを提供する。【解決手段】実施形態の眼科用顕微鏡システムの照明系は、被検眼に照明光を照射する。一対の受光系は、対物レンズ及び撮像素子をそれぞれ含み、互いの対物光軸が非平行に配置され、被検眼に照射された照明光の戻り光をそれぞれの対物レンズを介してそれぞれの撮像素子に導く。OCT系は、OCT光源からの光を測定光と参照光とに分割し、対物光軸と異なる方向から測定光を被検眼に照射し、被検眼からの測定光の戻り光を参照光と合成して得られた干渉光を検出する。光スキャナは、被検眼を測定光でスキャンするために用いられる。画像描出部は、一対の受光系の少なくとも一方の撮像素子からの出力に基づく画像に、光スキャナによるスキャン範囲を描出する。【選択図】図1
