Description
Изобретение относитс к способам исследовани оптических элементов глаза.This invention relates to methods for studying optical elements of the eye.
Недостатками существующих способов оценки видимых изменений в глазу при биомикроскопии вл ютс их субъективность, зависимость от квалификации наблюдател и отсутствие каких-либо количественных характеристик. Некоторые попытки получени количественных характеристик результатов измерений, например глубины передней камеры (барабан Ульбрихта), не дали полол ительных результатов вследствие неточности измерений.The disadvantages of the existing methods for assessing visible changes in the eye with biomicroscopy are their subjectivity, dependence on the qualifications of the observer, and the absence of any quantitative characteristics. Some attempts to obtain quantitative characteristics of the measurement results, for example, the depth of the anterior chamber (Ulbricht's drum), did not produce polol results because of inaccurate measurements.
Нредлагаемый способ биомикроскопни глаза почти полностью устран ет указанные недостатки и позвол ет осуществл ть непосредственные пространственные измерени видимых в свете щелевой ламны элементов оптических срезов глаза и глазного дна, с целью получени количественных характеристик дл контрол за течением патологических процессов в динамике.The proposed biomicroscopic eye method almost completely eliminates the indicated drawbacks and allows direct spatial measurements of the elements of optical sections of the eye and the fundus of the eye visible in the light of the slit lamina, in order to obtain quantitative characteristics for monitoring the course of pathological processes in dynamics.
Предлагаемый способ дает возможность измер ть толщину роговицы , глубину передней камеры, толщину хрусталика, глубину залегани патологических изменений в глазу, толщину кровеносных сосудов глазного дна, размеры патологических очагов и новообразований на глазном дне, степень проминенции соска зрительного нерва (например, при застойности соска), высоту отслойки сетчатки и р д других изменений.The proposed method makes it possible to measure the thickness of the cornea, the depth of the anterior chamber, the thickness of the lens, the depth of the pathological changes in the eye, the thickness of the blood vessels of the fundus of the fundus, the size of the pathological foci and tumors in the fundus of the optic nerve nipple (for example, when the nipple is stagnant) , height of retinal detachment and a number of other changes.
Высока точность измерений (пор дка 0,07 мм) позвол ет заметить малейшие изменени размеров объекта в динамике.The high measurement accuracy (on the order of 0.07 mm) makes it possible to notice the slightest changes in the size of an object over time.
Сущность предлагаемого способа заключаетс в следующем: наблюда в бинокул ре стереомикроскопа объемное изображение оптического среза глаза или глазного дна, совмещают пространственное изображение установленных в фокальной плоскости бинокул ра измерительных марок с исследуемыми точками объекта и, измер параллактические смещени при посадке марок на исследуемые точки, вычисл ют затем относительные положени их в пространстве.The essence of the proposed method is as follows: Observed in a binocular of a stereomicroscope a three-dimensional image of an optical slice of the eye or fundus, combine a spatial image of measuring marks installed in the focal plane of the binocular, and measuring the parallactic displacements when the marks are placed on the studied points, calculate then their relative positions in space.
128105- 2 Предмет изобретени 128105- 2 Subject of the invention
Стереоофтадьмометрический способ биомикроскопии глаза с помощью щелевой лампы, отличаю щ,и и с тем, что, с целью осуществлени , пространственных измерений элементов переднего отрезка глаза и глазного дна, производ т наведение видимых в поле зрени бинокул ра пространственных марок на измер емый предмет и измерение величин параллактических смещений, по,которым и суд т о пространственных размерах измер емого объекта.The stereo-ometric method of biomicroscopy of the eye using a slit lamp is distinguished by the fact that, in order to make spatial measurements of the elements of the anterior segment of the eye and the fundus, the spatial marks visible in the binocular field are directed to the measured object and the measurement parallactic displacements, according to which the spatial dimensions of the object being measured are judged.
