Abstract
Изобретение относитс к медицинской технике, в частности в офтальмологическим устройствам дл оценки помутнени сред глаз при диагностике их заболеваний. Цель - обеспечение возможности сравнительной оценки помутнени сред в одном глазу по отношению к другому. Устройство содержит источник света 1, объектив 2, светоделительную пластину 3, зеркало 4, нейтральный светофильтр 5 переменной плотности из двух клиньев со шкалой, компенсационный светофильтр 6, молочные стекла 7 и 7Ъ , диафрагмы 8 и 8Ъ. Действие устройства основано на принципе сравнени двух полей зрени , из которых одно рассматриваетс одним глазом наблюдател , а другое одновременно другим. В случае, если пол кажутс наблюдателю разной ркости, перемеща клинь светофильтра 5, он устанавливает равенство видимых ркостей обоих полей. Разности отсчетов в положении клиньев характеризует разницу в светопропускании и соответственно в помутнении сред одного глаза по отношению к другому. 2 ил.The invention relates to medical technology, in particular in ophthalmic devices for assessing the opacities of the eye in the diagnosis of their diseases. The goal is to provide the possibility of a comparative assessment of the turbidity of media in one eye relative to the other. The device contains a light source 1, a lens 2, a beam-splitting plate 3, a mirror 4, a neutral variable-density light filter 5 of two wedges with a scale, a compensation light filter 6, a milky glass 7 and 7, a diaphragm 8 and 8. The operation of the device is based on the principle of comparing two fields of view, one of which is viewed with one eye of the observer, and the other simultaneously with the other. If the field appears to the observer of different luminance, moving the wedge of the light filter 5, it establishes the equality of the visible forces of both fields. The difference in readings in the position of the wedges characterizes the difference in light transmission and, accordingly, in the turbidity of the media of one eye relative to the other. 2 Il.
