摘要：
The utility model relates to medicine, in particular for ophthalmology, and is designed to study the visual field of the human eye for the purpose of early diagnosis of primary glaucoma and other diseases of the field of view. The utility model comprises a projection screen with a viewing window for observing light test objects designed as a hollow sphere whose surface is located at least one light spot of the test object is white, and / or red and / or green colors for presentation to the patient . On the surface of a hollow sphere near the intersection of the central axis of the hollow sphere point passing through the center of the viewing window, with a hollow sphere surface opposite the viewing window fixed at least one fixation light test object intended for fixation sight, and a video camera for detecting movements of the patient pupil relative directions for light fixation test object located directly in the axis point of intersection with the surface of a hollow sphere. Along the edge of the viewing window is arranged at least one light source to illuminate the demo screen. Dimensions demo screen and the viewing window are respectively diameter (1,75-1,9) L and (0,85-1,1) L, wherein L - the horizontal dimension of the orbit human. Light test objects, a test object fixation and illumination light sources are connected to a multi-bit bus. Multi-bit bus and a video camera connected to the control and processing unit to which is also connected to the patient button "test object is visible" response. control and processing unit is adapted to display processing function and information.Полезная модель относится к медицине, в частности к офтальмологии, и предназначена для исследования поля зрения глаза человека с целью ранней диагностики первичной глаукомы и других заболеваний, ограничивающих поле зрения. Полезная модель содержит демонстрационный экран со смотровым окном для наблюдения световых тест-объектов, выполненный в виде полой сферы, на поверхности которой р
