Description
Technical field
The utility model relates to a kind of medical instrument more particularly to a kind of medical visual field instruments.
Background technique
Perimetry plays very important effect in the diagnosing and treating of ophthalmology disease.Perimetry is ophthalmology work
Person's diagnosis and the tracking main diseases causing blindness of follow-up provide important information.Beyond any doubt, perimetry is that diagnosis and monitoring are green
Light eye and some other vision, the basic skills of optic nerve disease.Advanced perimetry is early diagnosis and monitoring closely
The development of these diseases provides possibility, while successfully treatment creates condition.
The visual field is the peripheral space region closely seen when eyeball Xiang Zhengqian fixation is motionless.The discovery of the 17th century Mariotte
The relationship of optic papilla and physiologic scotoma, therefore become the people of first special dim spot of description.ThomasYang in 1801
The visual field is veritably measured for the first time.In the middle of the 19th century, Forster devises First arc perimeter, and such visual field meter will
Perimetry is expanded to 450, and determines the external world in the visual field.Bjerrum (1889) utility model visual field Tangent screen
With the more visual isopter visual field meters of dynamic.
20th century, Ferree and Rand have developed the work of Forster early stage, expand the inspection model of arc perimeter
It encloses.Arc perimeter adopts always so far.Since nineteen fifty, the projection-type hemispherical perimeter of Goldmann design persistently flows
It has gone 30 years.Background illumination, stimulation cursor size and its brightness are standardized by the visual field Goldmann meter, for carrying out dynamic
And vein perimetry, while it lays a good foundation for the more accurate modern visual field meter of development.Hereafter, Louisesloan first
Recognize the perimetric importance of static threshold type.Harms and Aulhorn provides the statement visual field of supplement for kinetic perimetry meter
It checks.They devise the manual visual field meter of Tubinger, can be completed at the same time dynamic and static perimetry.Armaly proposes super
The concept of threshold value screening, he, which also proposed, is easy injured visual field position in glaucoma.In the 1960s, Dubois-
Poulsen and Magis first attempts to utility model automatic dynamic visual field meter, but due to technical problem, is hindered.Lynn and
Tate1969 utilizes a computer and television set, rollout First AUTOMATIC STATIC visual field meter.Hereafter, AUTOMATIC STATIC
Visual field meter continues to develop, and is continuously improved.
Existing medical visual field instrument generally comprises the visual field meter and computer being independently arranged, the main-machine communication of the visual field meter and computer
Connection, perimetric running are controlled by host, and host is to can be obtained accurate result after detection data operation, to be green light
The diagnosis of the ophthalmology such as eye, retinopathy, optic nerve injury and Neurological disease provides the foundation of science.When hospital arranges, depending on
Open country meter is typically placed on desktop, and thus also resulting in perimetric height can not be adjusted, and patient can only initiatively adjust its body
For body posture so that its head adapts to perimetric height, this has just aggravated burden of patients, and often due to body it is uneven and
It is mobile to cause its head, so that fixation can not be remained during the inspection process, head movement drives the movement of eyeball and causes
The offset in the visual field causes the detection site photo threshold occurred deviation occur (may enhance may also weaken).
Therefore, to solve the above problems, just needing a kind of medical visual field instrument, it can facilitate and adjust perimetric height, from
And the patient of different heights is adapted to, mitigate burden of patients, and be conducive to keep the balance of patient body, prevents because its head is mobile
And reduce the accuracy checked.
