Introduction and objective: In recent years, significant progress has been made in the diagnosis of vestibular pathologies, especially in the use of alterations in eye movements for diagnosis. An orderly way of evaluating ocular motor function in patients with vestibular system involvement is presented in this review. Method: Narrative review. Results: 7 articles were selected. Discussion: The use of ABCs mnemonics is proposed to order the examination of oculomotor function in patients with vestibular system involvement. The "ABC" segment involves the evaluation of the Conjugated Ocular Bilateral Alignment; "D" is the examination of the Dynamics of eye movements; "E" refers to the stability of the oculomotor system; "FGHI" refers to Eye Fixation, Gain in movements and Head Impulse (cephalic impulse). Conclusions: Using this approach, omissions are avoided in the semiological examination and it can share the information in a homogeneous way among health professionals.
