摘要:
PROBLEM TO BE SOLVED: To provide a scanning laser ophthalmoscope capable of changing over a photographic view angle to excellently photograph a fundus image.SOLUTION: An ophthalmic photographing device includes, in a photographic optical system, an objective lens optical system including at least a first convex lens 16a and a second convex lens 16b positioned on a scanning part side thereof, forming a pivoting point of laser light on an examined eye E side of the first convex lens 16a, and leading the laser light pivoted around the pivoting point to a fundus. The ophthalmic photographing device includes a lens movement mechanism capable of changing over a photographic view angle in the photographic optical system between a first view angle and a second view angle wider than the first view angle by changing arrangement of the first convex lens 16a and the second convex lens 16b. The ophthalmic photographing device is disposed with the first convex lens and the second convex lens by the lens movement mechanism such that a position of the pivoting point is maintained when the photographic view angle is the first view angle and when the photographic view angle is the second view angle.
