摘要:
A retinal disease analyzer processes data obtained by processing a color retinal image and measured visual field data provided by a perimeter to detect the condition of the optic disc and defects in the nerve fiber bundles for the clinical analysis of the condition of the optic disc and the defects in the nerve fiber bundles, and combines detected information on a fundus coordinate system taking into consideration the arrangement of the nerve fiber bundles for the comprehensive analysis of the condition and the degree of progress of glaucoma. The detected information is analyzed on the basis of the distribution pattern of the nerve fiber bundles or the corresponding fundus coordinate system to integrate all the data for analysis. The condition and the degree of progress of glaucoma can be determined on the basis of the integrated data.

The present invention relates to an ophthalmological analyzer, and an object of the present invention is to provide an ophthalmological analyzer capable of making information on the shape of an optic nerve conform to the test results of an eyeground or a visual field to be tested by using a look-up table or the like. The ophthalmological analyzer comprises a recording unit for recording at least test data on subjects and information on shapes of optic nerves, a data input unit to be operated by a tester to enter characters and values for coordinates, and a controller which carries out an analytical operation on the basis of the test data on the subject and the information on the shape of an optic nerve, read from the recording unit. The controller is capable of selecting a piece of information to be used among a plurality of pieces of information on the shapes of optic nerves, of changing at least part of information on the shape of an optional optic nerve or of producing information on the shape of a new optic nerve.

The present invention relates to a perimetric instrument for measuring a range of a visual field of an eye of a man, and more particularly to a perimetric instrument which includes an abnormal visual field pattern analogical inferring section using a multilayer neural network and can analogically infer an abnormal visual field pattern of a measurement object person. Further, the present invention provides a perimetric instrument which can automatically make a determination of an additional target. In particular, according to the present invention, a multilayer neural network including an input layer, hidden layers and an output layer introduces a neural weight ratio which is determined based on responses when the visual field is normal and abnormal, and as a response from a responding section is inputted to the input layer while an output from the output layer is sent out to an analogical inferring section, the analogical inferring section can analogically infer an abnormal visual field pattern of the measurement object person. Accordingly, it is possible to help judgment of an abnormal visual field pattern by a measurer, and since also labor, time and so forth of the measurer are reduced, burdens to the measurer and them easurement object person can be reduced remarkably.

The spray gun is provided with a nozzle section which mixes gas into raw material liquid and also ejects the raw material liquid. The internal space of the nozzle section has an introduction path into which the raw material liquid is introduced, an open portion in which a flow path is enlarged more than the introduction path, thereby ejecting the raw material liquid in a fine particle form, a reduced diameter portion in which a flow path is made narrower than the open portion, thereby re-aggregating the raw material liquid in a fine particle form, and an ejection orifice portion which ejects the raw material liquid to the outside. In the nozzle section, a gas introduction hole which introduces gas into a base-end-side portion of the open portion is formed.

An accessory capable of communicating with a camera, includes a terminal section having a plurality of terminals. The plurality of terminals include a startup state providing terminal that provides, to the camera, a detection level by which the camera detects that the accessory is capable of being started up, a data signal terminal that outputs a data signal including information regarding the accessory to the camera, and a first reference potential terminal having a reference potential of the detection level and the data signal. The startup state providing terminal is disposed adjacent to the data signal terminal, and the first reference potential terminal is adjacent to the data signal terminal, and is disposed with the data signal terminal interposed between the startup state providing terminal and the first reference potential terminal.

An object of the present invention is in that a body waste treating material can be manufactured by using a defective fibrous material unsuitable for forming paper generated upon treating a pulpable raw material without materials for complementing a water absorptive property and a water retention property and a wasting step in manufacturing at a low cost, and resources may be efficiently used.[Solution to Problem]This invention is characterized by molding a defective fibrous material unsuitable for forming paper that is a fibrous material obtained by defiberizing and dehydrating a pulpable raw material to a certain shape. The defective fibrous material is characterized by including thin and/or short fibers.
摘要:
A perimeter capable of objectively adding useful testing points without relying on an operator's intuitional judgment, and capable of performing a reliable test of the field of vision without imposing a useless burden on a subject. The perimeter includes a CPU 11 and a display portion 18. The CPU 11 forms data, which include estimated values, on a visual field characteristic distribution by making an interpolation between tested values of a subject's eye which are obtained by exhibiting a plurality of targets. The display portion 18 displays an unreliable distribution WP indicating a domain estimated to be distant from the tested values on the basis of data on the visual field characteristic distribution and data, which include the tested values, on a distribution of an estimated neighborhood of the tested values.
