Purpose: To detect the muscle affected in vertical deviation induced by a single muscle.
Material and methods: A table was formed combining the Parks-Bielschowsky and Bajandas tests.
Result: Detection of the muscle affected in vertical deviation induced by a single muscle is made possible by means of the table
formed in accordance with the principles of the Parks-Bielschowsky and Bajandas tests.
Conclusion: If a single muscle is responsible for the deviation, it can be determined using these two tests. However, application
of these tests may, on occasions though, cause some confusion. Through the table, it is quite easy for physicians to detect the affected
muscle using the directions mentioned in the Table 1.
