An image processing apparatus includes a detecting unit configured to execute structural analysis on a tomographic image acquired by an acquiring unit and detect an abnormal portion of the eye; and a display control unit configured to cause a displaying unit to display a finding of the abnormal portion detected by the detecting unit, as a sentence or a word in a manner superimposed on the tomographic image.

An apparatus and method for aiding in the detection of dementia, concussion, other neurologic conditions, retinal, and optic nerve conditions. The apparatus enables the diffusion coefficient of the tissue to be ascertained and studied by directing the light from a laser or other coherent light source at the patient's retina, optic nerve or choroid and measuring the fluctuations in the intensity of the back-scattered light caused by the movement of light scatterers in the tissue. By comparing the measurements to a normal database, or to the subject's previous measurement, in combination with an eye examination and OCT image/measurement the changes caused by the disease and the effectiveness of therapy can be ascertained. The disclosed apparatus allows the incident and detection optics to be attached to ophthalmic devices typically used in ophthalmologic care. Also, where both the incident laser fiber optic and the detection fiber optic are directly connected to goggles, one or more or all of the above-described mirrors may not be necessary, as both fiber optics are preferably directly directed into the eye.

An ophthalmic imaging apparatus of an embodiment scans a subject's eye with OCT to acquire a cross sectional image. A measurement unit performs OCT. An imaging unit acquires a moving image of the subject's eye. A display controller controls a display device to display the moving image acquired by the imaging unit, and two or more scan pattern images corresponding to two or more scan lines representing scan positions and scan directions in the moving image and arranged such that at least two of the two or more scan pattern images intersect one another. An operation unit is used for changing a relative position between the two or more scan pattern images. A measurement controller controls the measurement unit to perform OCT based on the two or more scan lines corresponding to the two or more scan pattern images after the relative position have been changed.
