“…18,19 However, most investigators who have actually studied and quantified ocular torsion found it is rather small and only partially compensates for head tilt. [20][21][22][23][24][25][26][27][28][29] Although the methodology used in these studies varied, the results of all found that the partial compensatory countertorsion present after head tilt was in the range of 10% to 30% of the size of the head tilt. Thus, for a 30-°tilt, the countertorsion would be between 3°and 9°.…”

“…As a result, the eyes rotate around the visual axis in a direction opposite the head tilt. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] However, this compensatory eye movement, ocular counterrolling (OCR), compensates for only approximately 10% to 20% of head tilt. 1-9,11,14 -16 The Bielschowsky head tilt phenomenon (BHP) is used to diagnose superior oblique (SO) palsy and is characterized by an elevation of the paretic eye when the head is tilted toward the shoulder on the side of the lesion.…”

“…A primeira referência a torção ocular reflexa foi creditada a Hunter* em 1786 (6) quando, diante do espelho, notou movimento rotacional dos olhos durante inclinação lateral da cabeça Em 1866, Javal** (6) , observou uma redução de acuidade visual com seus óculos para astigmatismo, quando inclinava a cabeça lateralmente. Durante certo período houve dúvida quanto à existência ou não de uma rotação ocular compensatória, o denominado reflexo óculo-vestibular (1,(7)(8) questionaram a existência deste reflexo. Atualmente está comprovado que, quando a cabeça é inclinada para um lado, produz-se de imediato um movimento dos olhos no sentido oposto.…”
