A fundus observation apparatus that is capable of assisting an examiner in judging the presence or absence of abnormality in an examinee's eye based on a fundus tomographic image. The fundus observation apparatus includes an optical coherence tomography device that has an optical scanner for setting an image pickup position on a fundus of an examinee's eye, and is arranged to obtain a tomographic image of the fundus, and an information display unit that is arranged to display on a monitor the tomographic image obtained by the optical coherence tomography device and assisting information for assisting an examiner ...
We report the first case in the literature of chorioretinal atrophy involving the macula in an 11-year-old girl with Alagille syndrome, as examined by optical coherence tomography, and fundus autofluorescence imaging. Funduscopy revealed diffuse choroidal hypopigmentation with increased visibility of the choroidal vessels and symmetric, well circumscribed macular discoloration. Anomalous oblique configuration of the optic disc and peripapillary tortuous vessels were also detected. Optical coherence tomography demonstrated decreased retinal thickness, especially the outer retinal layer, and the photoreceptor inner segment/outer segment junctions were irregular and discontinued, corresponding to macular discoloration. Fundus autofluorescence imaging clearly defined hypofluorescent areas in the ...
An ophthalmic observation apparatus that is capable of performing follow-up of an examinee's eye efficiently and suitably. The ophthalmic observation apparatus for observing an image of an examinee's eye that is obtained by an ophthalmic photographing apparatus includes an input device arranged to output an operation signal given by an examiner, a monitor, and a display control unit arranged to display a first image and a second image of a same portion of the examinee's eye that are obtained at different dates and times of examination on the monitor in a comparable manner, and when changing a ...
An apparatus for generating a two-dimensional image of an object using an optical coherence tomography (OCT) optical system, includes: the OCT optical system including: a light source; a splitter for splitting light emitted from the light source into a measurement optical path and a reference optical path; a scanner arranged in the measurement optical path for scanning the object in at least one of XY directions with the split light; and a detector for detecting a spectrum of combined light of the split light from the measurement optical path reflected on the object and the split light from the reference ...
