Description

Haiding lattice brush training instrument with adjustable pictures

Technical Field

The utility model belongs to the technical field of amblyopia training appearance, concretely relates to picture adjustable Haiding lattice brush training appearance.

Background

The basic principle of the Haidinger brush is that according to the instantaneous Haidinger brush effect, when a patient looks at intense light through a rotating blue polarized glass plate, an inward vision phenomenon occurs, and a pair of purple-blue rotating brush-shaped images appear in the visual field, and the effect only appears on the fovea of macula lutea. When the patient observes the brush-shaped image in a rotating state through the instrument window, the brush-shaped image is necessarily projected to the fovea of the macula of the retina and is watched through the fovea. The optical brush treatment is just to stimulate the inhibited macula lutea by the brush-shaped image in the rotating state, thereby achieving the purposes of changing the fixation property and improving the eyesight.

The Haidinger phenomenon is a phenomenon unique to the fovea centralis of the macula lutea, the Haidinger phenomenon can only occur when an object image projection point is within 3 degrees of the fovea centralis of the macula lutea, and the treatment of the eccentric amblyopia by all the Haidinger brushes is mainly used for the consolidation treatment after the eccentric fixation within 3 degrees and the treatment of the afterimage and the curative effect consolidation after the change of the eccentric fixation amblyopia fixation property

When Haidinger brush training is carried out, a trainer is guided by corresponding pictures, a macular fixation point is transferred to a 3-degree ring of a macular fovea, the change of fixation property and eccentricity is checked according to the training progress and effect, and different pictures are replaced; the Haiding lattice brush on the existing market is designed in a monocular mode, a picture is single, the size of a window can not be adjusted, the picture is often replaced manually, another eye needs to be covered or closed during use, the lower jaw cannot support the picture, long-time training is tedious and tasteless, the posture support difficulty is large, and left and right eye switching cannot be completed.
