An ophthalmic apparatus for photographing an eye to be examined having a photographing optical system for photographing the eye, the apparatus comprising a judging device for judging whether or not a picture image photographed by the photographing optical system satisfies a predetermined image requirement, an informing device for informing a result judged by the judging device.

Ophthalmic apparatus for photographing an eye to be examined

An ophthalmic apparatus for photographing an anterior part of an eye to be examined, the apparatus comprising a sectional image photographing optical system for photographing a sectional image of the anterior part of the eye, a rotating device for rotating the sectional image photographing optical system, a retroillumination image photographing optical system for photographing a retroillumination image of the anterior part of the eye, a determining device for obtaining a rotation angle that the sectional image photographing optical system is to be rotated by the rotating device based on the retroillumination image photographed by the retroillumination photographing optical system and a controlling device for controlling operation of the rotating device based on the rotation angle obtained by the determining device.

Ophthalmic apparatus for photographing an anterior part of an eye

An ophthalmic apparatus for analyzing a section of an anterior part of an eye providing an input device for inputting a photographed image data of corneal section which is cut optically by a slit light, an image memory for memorizing the image data of corneal section inputted by the input device, an image analyzing device for analyzing an optical density of the image of corneal section by processing the image data of corneal section memorized by the image memory, and a display device for displaying an analyzed result of the image analyzing device.

Opthalmic apparatus for analyzing a section of an anterior part of an eye

Ophthalmic photographing apparatus for photographing an anterior part of examinee's eye provides an alignment optical system including a reflection image forming device for forming an image reflected on the cornea of the examinee's eye, an observation optical system for observing image of the anterior part of the examinee's eye, comprising an alignment reticle, and a photographing optical system for photographing the anterior part of the examinee's eye. The picture image data of the anterior part of the eye photographed with the photographing optical system is memorized by a picture image data memory, and an alignment deviation is detected by operating the memorized picture image signal to detect a designated part and by finding a dislocation distance of the designated part from a reference position, and an analyzing position of the image is corrected on the basis of the alignment deviation and the picture image of the anterior eye is analyzed.
