Oblique diaphragm stereoscope is a commonly used orthostatic vision training instrument. Oblique diaphragm stereoscope can not only eliminate inhibition through depiction and capture training, but also train the convergence and dispersion ability of both eyes. Oblique diaphragm stereoscope can be used for visual rehabilitation training at all ages. Because oblique diaphragm stereoscope is simple, lightweight and easy to carry, It is also a common home visual rehabilitation training instrument.

Method: 

① Fix one of the cards with vertical lines at the bottom of each group at the position of "0" scale, and place the other on the top of the side of the solid mirror close to the reflector, and fix it with clips. The left and right eyes of the patient can see different patterns respectively.

② Keep your eyes close to the eyepiece and watch at the same time. At this time, the patterns in the two cards are fused into one, which is gradually clear, and the circle will feel floating.

③ When the reflector partition plate is placed to the left, the card on the base plate moves to the left for collective function visual rehabilitation training, and when it moves to the right for scattered function visual rehabilitation training.

④ The reflector diaphragm is placed to the right, the card on the base plate moves to the left for scattered functional visual rehabilitation training, and moves to the right for collective functional visual rehabilitation training.      

Indications: Binocular convergence and divergence dysfunction
