- the numerical values of the anterior chamber depth, the axial length, and the refractive index of the subject's eye measured by the ophthalmic apparatus 200 are compared with the predetermined reference values, and the problem of each item is solved.
- the presence or absence is determined, and based on the combination of the presence or absence of problems in each item, it is determined whether the subject is a glaucoma candidate who is at risk of glaucoma.
- An ophthalmologist or the like can diagnose whether there is a risk of glaucoma by referring to the judgment, and take the following actions such as follow-up, other tests, or treatment.
- the determination unit 112 places the highest priority on whether or not there is a problem with the anterior chamber depth among the subjects among the items.
- the standard for the depth of the anterior chamber is preferably whether or not the depth of the anterior chamber is less than 2.0 mm.
- the reference value for each item can be set as appropriate, but by setting such an appropriate quantitative standard, it is possible to make a clearer judgment. This is because when the depth of the anterior chamber is smaller than a certain value (shallow) such as less than 2.0 mm, the intraocular pressure increases and the possibility of developing glaucoma increases.
- the determination unit 112 compares the anterior chamber depth of the subject with the reference value of the anterior chamber depth, and outputs information determined to be problematic when the anterior chamber depth of the subject is small (shallow). .. Regarding the depth of the anterior chamber, even if there is a problem only with this item, it may be judged as a person who may have glaucoma.
- the standard of the axial length is preferably whether or not the axial length is 26.5 mm or more. This is because myopia is progressing when the axial length is 26.5 mm or more (longer) than a certain value, and myopia is considered to be one of the risk factors for glaucoma.
- the determination unit 112 compares the axial length of the subject with the axial length of the reference value, and outputs information determined to be problematic when the axial length of the subject is large (long). .. Regarding the axial length, it is preferable to use the depth of the anterior chamber as the most important factor and use it as an auxiliary item to make the judgment more reliable.
- the standard of the refraction power is preferably whether or not the refraction power shows a refraction stronger than -8D. This is because myopia is progressing when the refractive power becomes larger (stronger) than a predetermined standard, such as when the refractive power is -8D, and myopia is considered to be one of the risk factors for glaucoma. ..
- the determination unit 112 compares the refractive power of the subject with the refractive power of the reference value, and outputs information determined to be problematic when the refractive power of the subject is strong.
- the anterior chamber depth As with the axial length, it is preferable to use the anterior chamber depth as an auxiliary item for making the judgment more reliable with the anterior chamber depth as the most important factor. Therefore, if there is a problem only with this item, it is not preferable to judge as a person who may have glaucoma. It is preferable to make a judgment by combining the anterior chamber depth and the refractive power, or to make a judgment by combining the anterior chamber depth, the axial length and the same number of refractions. For example, if there is a problem with the depth of the anterior chamber and there is also a problem with the refractive power, it may be judged as a person who may have glaucoma comprehensively. Alternatively, if there is a problem with the depth of the anterior chamber, a problem with the axial length, and a problem with the refractive power, it may be judged as a person who may have glaucoma comprehensively.

- the ophthalmology information processing server, the ophthalmology information processing program, and the ophthalmology information processing method according to the embodiment of the present disclosure, whether or not the person has a risk of glaucoma is determined by using the items measured by the ophthalmology apparatus 200 as they are. You can judge.
- an ophthalmic apparatus 200 capable of measuring all of the anterior chamber depth, the axial length, and the refractive power with the same apparatus, it is possible to determine whether or not there is a risk of glaucoma based on a plurality of items. .. An example of a case where a judgment is made using such a plurality of items will be described.
- Example 3-1 when making a judgment using all three items of anterior chamber depth, axial length, and refractive power, as shown in Example 3-1, Example 3-2, and Example 3-3, the comparison results of the three items are used. Based on this, the risk of glaucoma may be judged by a stepwise evaluation such as large to small. For example, in Example 3-1 it is said that there is a problem in the axial length and the refractive index in addition to the depth of the anterior chamber, and the axial length related to axial myopia and the refractive myopia are related. By referring to both the degrees of refraction, the accuracy of the judgment is improved.
- the axial length is more important than the refractive power, so that it may be judged that the risk of Example 3-3 is smaller. ..
- the refractive power even if there is a problem with both the axial length and the refractive power as in Example 3-4, if there is no problem with the depth of the anterior chamber, it is not selected as a candidate who may have glaucoma at this time, and follow-up observation is performed. You may decide that. Similarly, if there is no problem with the depth of the anterior chamber and there is a problem with the item related to myopia, it is possible that it is just myopia.

Abstract
Description
以下、本開示の実施形態を図面に基づき説明する。図1は、本開示の実施形態に係る眼科情報処理システム1を示すシステム構成図である。この図においては、眼科情報処理システム1は、情報管理サーバ101、眼科装置200、端末装置300が別異の装置であり、互いにネットワークNWで接続されている構成の例を示している。なお、眼科情報処理システム1は、全ての構成を一体の装置としたスタンドアローン型としてもよい。あるいは、眼科情報処理システム1による緑内障のおそれある者の選別機能が、眼科装置200の1つのモードとして搭載されていてもよい。ここで眼科装置200は、眼科情報処理システム1により緑内障のおそれのある被検者を候補者として選別するための、前房深度、眼軸長、屈折度数を測定し取得するための測定装置として機能するものである。また、前房深度、眼軸長、屈折度数は他の外部の眼科装置200から取得して記憶しておくことにより、選別の段階では直接的に眼科装置200を必要としない眼科情報処理システム1であってもよい。
以下では、各構成を説明しながら本開示の緑内障のおそれのある被検者の選別機能について説明する。
次に、図5は、本開示の実施形態に係る眼科情報処理システム1の情報管理サーバ101において実行される処理の主な流れについて説明するフローチャートが示されており、以下、同フローチャートに沿って眼科情報処理方法を説明する。なお、当該フローチャートは一例であり、眼科情報処理方法は当該フローチャートの処理に限られるものではない。
図6は、コンピュータ801の構成を示す概略ブロック図である。コンピュータ801は、CPU802、主記憶装置803、補助記憶装置804、インタフェース805を備える。
