An ophthalmic apparatus of an aspect example includes an image acquiring unit, a corneal shape estimating processor, and a first image correcting processor. The image acquiring unit is configured to acquire an anterior segment image constructed based on data collected from an anterior segment of a subject's eye by optical coherence tomography (OCT) scanning. The anterior segment image includes a missing part corresponding to a part of a cornea. The corneal shape estimating processor is configured to estimate a shape of the missing part of a cornea image by analyzing the anterior segment image acquired by the image acquiring unit. The first image correcting processor is configured to correct distortion of the anterior segment image based at least on the shape of the missing part estimated by the corneal shape estimating processor.

Ophthalmic apparatus, method of controlling the same, and recording medium

Provided are an ophthalmologic device and a method of controlling the same capable of accurately and reliably acquiring ocular characteristics of a subject eye. The ophthalmologic device includes: a face supporting unit configured to support a face of an examinee; an anterior ocular segment image acquiring unit configured to repeatedly acquire an anterior ocular segment image of the subject eye of the face supported by the face supporting unit; a pupil image detecting unit configured to detect a pupil image of the subject eye for each anterior ocular segment image based on the anterior ocular segment image repeatedly acquired by the anterior ocular segment image acquiring unit; and a determining unit configured to determine whether or not the face is properly supported by the face supporting unit based on a result of detection of the pupil image for each anterior ocular segment image by the pupil image detecting unit.

Ophthalmologic device and method for controlling same

An ophthalmic apparatus of an aspect example includes an image acquiring unit, a first image region identifying processor, and a second image region identifying processor. The image acquiring unit is configured to acquire an anterior segment image constructed based on data collected from an anterior segment of a subject's eye by OCT scanning. The first image region identifying processor is configured to identify a first image region corresponding to a predetermined part of the anterior segment by analyzing a first part of the anterior segment image acquired by the image acquiring unit. The second image region identifying processor is configured to identify a second image region corresponding to the predetermined part based on the first image region identified by the first image region identifying processor, the second image region being inside a second part that includes the first part as a proper subset.

An ophthalmic apparatus of an embodiment example applies an OCT scan to an anterior segment and constructs an image from acquired data. Further, the ophthalmic apparatus analyzes the image to detect an artifact along an A-scan direction and moves an OCT optical system based on the artifact. Also, the ophthalmic apparatus analyzes the image to detect a corneal image and judges whether an intersection between the artifact and the corneal image is located within a predetermined area. In addition, the ophthalmic apparatus calculates an image quality evaluation value of the image, and controls the OCT optical system to perform an OCT scan of a predetermined pattern if the intersection is located within the area and the image quality evaluation value is equal to or greater than a predetermined threshold.

An alarm management apparatus of the present disclosure presents a trigger alarm, which should be presented to an operator, to the operator when the trigger alarm is included in an alarm that is received or generated. The alarm management apparatus stores a suppressed alarm related to the trigger alarm, without presenting the suppressed alarm to the operator, when the suppressed alarm is included in the alarm and presents the stored suppressed alarm to the operator based on an operation by the operator.

Alarm management apparatus, alarm management system, and alarm management method

A scan area setting unit of an exemplary ophthalmic apparatus sets a scan area in a region passing through an iris outer edge. A first scan controller controls an OCT optical system to apply an OCT scan to the scan area. An image quality evaluating unit calculates an image quality evaluation value of an image from the OCT scan. A corner angle image detecting unit analyzes the image to detect a corner angle image. A position judging unit judges whether the corner angle image is located within a first area in an image frame. A second scan controller controls the OCT optical system to apply an OCT scan of a predetermined pattern to the anterior segment, if the image quality evaluation value is equal to or greater than a threshold and the corner angle image is located within the first area.

An ophthalmologic apparatus of an embodiment example includes a front image acquiring device, a first search processor, and a second search processor. The front image acquiring device is configured to acquire a front image of a fundus of a subject's eye. The first search processor is configured to search for an interested region corresponding to an interested site of the fundus based on a brightness variation in the front image. The second search processor is configured to search for the interested region by template matching between the front image and a template image in the event that the interested region has not been detected by the first search processor.

Ophthalmologic apparatus, and method of controlling the same

An ophthalmologic processing apparatus according to embodiments acquires data of a fundus of a subject's eye optically. The ophthalmologic apparatus includes a fixation system, an image acquisition unit, a specifying unit, and a determination unit. The fixation system is configured to project fixation light onto an eye of a subject. The image acquisition unit is configured to acquire an image of the fundus of the subject's eye in a state where the fixation light is projected by the fixation system. The specifying unit is configured to analyze the image acquired by the image acquisition unit to specify an image region corresponding to a predetermined site of the fundus. The determination unit is configured to determine whether or not the image region specified by the specifying unit is included within a predetermined range in the image acquired by the image acquisition unit.
