• A graphic technique is used to analyze cyclovertical muscle palsies. This technique is similar to that presented in the Ophthalmology Basic and Clinical Science Course, but has the following advantages: only one diagram is required to apply the method, and knowledge of the actions of the cyclovertical muscles, when analyzing the Bielschowsky head tilt test, is not required.
