“…The mean FPA of both eyes was 11.55°in our patients with trochlear nerve palsy (95 % CI 9.98-13.11) and 5.80°in our healthy subjects (95 % CI 4.93-6.66), which is in line with the current literature (11.5°for patients with trochlear nerve palsy [6], and up to 12.5° [14], 5-13° [3], 5.8-6.5° [12] for healthy subjects). Interestingly, our data confirmed that torsional misalignment in trochlear nerve palsy can shift to the non-affected side, which is a phenomenon that has been described in detail by Kushner et al [4].…”

“…Subjective tests are the double Maddox rod test, the Harms tangent screen, or the Lancaster red-green test [4 -6]. Objectively, ocular torsion can be measured using fundus photography [6,7] or the search coil technique [8]. However, the latter is invasive and not routinely applicable in daily clinical practice.…”

“…In acquired unilateral palsies objective methods consistently show a greater amount of torsion than subjective tests (Roh and Hwang 2011). Subjective methods include the major amblyoscope, double Maddox rod, Lancaster red-green test and the torsionometer.…”

“…Unilateral superior oblique palsy (USOP) induces torsional misalignment in both eyes [1,2]. Sensory tests for ocular torsion, such as the double Maddox rod test, Lancaster test, and examination with an amblyoscope, sufficiently demonstrate extorsional sensory states in patients with USOP [1,3,4]. However, the paretic eye in USOP does not always show extorsion on fundus photography [1,[5][6][7].…”

Background/Objectives To compare ocular torsion between congenital and acquired unilateral superior oblique palsy (USOP). Subjects/Methods Retrospective review was performed on medical records of 163 USOP patients. Qualitative fundus torsional states in both eyes were determined based on locations of optic disc and fovea. Disc-fovea angles (DFA) were collected in both eyes for quantitative analysis. DFAs and the proportions of qualitative fundus torsional states in paretic and non-paretic eyes were compared between USOP patients and normal controls, and between congenital and acquired USOP patients. Results This study included 90 patients with congenital USOP, 73 patients with acquired USOP, and 66 normal controls. Most control subjects showed no torsion in both eyes (93.9%), whereas 61.1% of congenital and 46.5% of acquired USOP patients showed extorsion in either eye. More patients with congenital USOP showed fundus extorsion in the non-paretic eye (24.4% versus 12.3%) or both eyes (20.0% versus 6.8%), compared with patients with acquired USOP (P = 0.007). DFAs of paretic and non-paretic eyes were larger in USOP patients than in normal controls (P < 0.001, for both congenital USOP versus control and acquired USOP versus control). DFAs of non-paretic eyes were larger in congenital USOP patients than in acquired USOP patients (10.3°versus 8.5°, P = 0.018). Conclusions Congenital USOP showed greater fundus extorsion in the non-paretic eye, compared with acquired USOP. Fundus photographs of both eyes are necessary to understand the ocular torsion in USOP patients and the variations in fundus torsion with varying USOP aetiology.

Comparison of subjective and objective torsion in patients with acquired unilateral superior oblique muscle palsy

Abstract: Objective extorsion may be found in all patients with acquired unilateral SOP, whereas subjective extorsion may be found in most patients with acquired unilateral SOP; the latter was detected more frequently with the DMRT than with the LRGT.
