Objective To design a random-dot stereopsis test system based on computer with single or double screen displaying. Methods ①The red-green glasses in single-screen examination or synoptophore in double-screen examination were adopted. The test condition ig. size and color of random dot,could be regulated according to requirement of experiment and clinical examinations. By using this system,the stereopsis in different distance could be examined with more acuity because it could erase the influence of anisekonia and strabismus.②The TNO imitating single or double-screen displaying parameters were applied for examination in 65 subjects. The results were compared with that in TNO examination. Results Comparing the results of random dot stereogram displayed in single and double-screen with that in TNO stereogram,significant difference was not found. Conclusion It is demonstrated that this stereopsis test system has the same accuracy as TNO stereogram,it can be applied to clinical examination and experimental study.
