Description
Изобретение относитс к приборам дл исследовани глаза.The invention relates to devices for examining the eye.
Недостатки существующих приборов дл периметрии заключаютс в том, что при темновой периметрии исследователь перемещает источник света по дуге периметра вручную, так как специальные приборы дл темновой периметрии сложны и широка больнична сеть их не имеет. Кроме того, результаты исследовани недостаточно точны.The disadvantages of existing devices for perimetry are that, with dark perimetry, the researcher moves the light source along the perimeter arc manually, since special devices for dark perimetry are complex and the wide hospital network does not have them. In addition, the research results are not accurate enough.
Применение предлагаемой приставки к проекционному периметру дает возможность устранить указанные недостатки.The application of the proposed attachment to the projection perimeter makes it possible to eliminate these drawbacks.
На чертеже показана предлагаема приставка.The drawing shows the proposed prefix.
Зеркальце / с руко ткой крепитс при помощи винта 2 к концу стержн 3, второй конец которого при помощи втулки 4 соединен с муфтой 5, представл ющей собой копию кожуха верхней головки периметра. С помощью муфты 5 вс приставка крепитс на верхней головке периметра вместо ее кожуха таким образом, чтобы пучок света, падающий на дугу периметра, точно освещал центр зеркальца. Отраженный от зеркальца пучок света направл етс на исследуемый глаз, который должен находитьс в центре дуги периметра.The mirror / handle is attached with a screw 2 to the end of the rod 3, the second end of which is connected with a sleeve 4 to a sleeve 5, which is a replica of the casing of the upper perimeter head. Using clutch 5, the prefix is mounted on the upper perimeter head instead of its casing so that a beam of light falling on the perimeter arc accurately illuminates the center of the mirror. The beam of light reflected from the mirror is directed to the eye being examined, which should be located in the center of the perimeter arc.
Сущность способа исследовани предлагаемой приставки заключаетс в том, что дл исследовани проекции света и границ пол зрени используетс отраженный от передвигающегос по дуге периметра зеркальца световой пучок различного диаметра, ркости и цвета.The essence of the method of investigating the proposed attachment is that to study the projection of light and the borders of the field of view, a light beam of different diameter, brightness and color is reflected from the mirror moving along the perimeter of the mirror.
Результаты исследовани фиксируютс на бланк так же, как и при обычной периметрии.The results of the study are recorded on the form in the same way as with conventional perimetry.
Предмет изобретени Subject invention
Приставка к проекционному периметру дл темновой кол-ичественной периметрии, отличающа с тем, что, с целью обеспечени простоты и точности исследовани пол зрени при помутнении сред глаза, онаThe prefix to the projection perimeter for the dark number of qualitative perimetry, characterized in that, in order to ensure simplicity and accuracy of the examination of the visual field when the medium of the eye is clouded,
состоит из зеркальца, руко тки и стержн , которые с помощью муфты закрепл ютс на верхпей головке проекционного периметра.It consists of a mirror, a handle and a rod, which are fastened with a clutch to the top of the projection perimeter head.
