“…Similarly, Shin et al 8 reported ocular torsion in at least one eye in 30% of IXT patients. Additionally, Khanna et al 18 found that 59% of patients with infantile esotropia exhibited ocular torsion. These findings indicate that objective ocular torsion is not exclusive to cases of cyclovertical strabismus but also occurs in horizontal strabismus.…”

“…For instance, a study involving 60 children aged 3–14 years with IXT accompanied by ocular torsion demonstrated a significant decrease in the degree of ocular torsion after lateral rectus recession 9 . Similarly, Khanna et al 18 investigated the effect of unilateral horizontal rectus surgery on objective ocular torsion in 68 children aged 4–16 years with congenital esotropia. They also reported a significant decrease in the incidence of ocular torsion after surgery, with a significant decrease in DFA in eyes with extorsion and a significant increase in DFA in eyes with intorsion postoperatively 18 .…”

We aim to explore the alterations of objective ocular torsion after unilateral lateral rectus recession-medial rectus resection (R&R) for intermittent exotropia (IXT). Seventy-two IXT patients undergoing R&R between March and June 2023 were enrolled. Ophthalmological examinations were performed before surgery and at 1 week and 1 month after surgery, mainly including prism and alternate cover test and optical coherence tomography. The mean disc-foveal angle of eyes showing intorsion significantly increased from − 1.5 ± 0.9° preoperatively to 2.0 ± 2.0° at 1 week (P = 0.0227) and 2.2 ± 1.6° at 1 month postoperatively (P = 0.0054). The mean disc-foveal angle of eyes exhibiting extorsion significantly reduced from 12.8 ± 1.9° preoperatively to 9.8 ± 3.1° at 1 week (P < 0.0001) and 9.7 ± 2.7° at 1 month postoperatively (P < 0.0001). The improvement of ocular extorsion at postoperative 1 month was more pronounced in patients with extorsion in operative eye compared to those with extorsion in inoperative eye (P = 0.0101). The improvement of ocular torsion was observed following R&R for IXT, with a greater effect noted in cases where the surgery was performed on the eye exhibiting extorsion.

“…Based on the position of the fovea, we considered the eye to be in extorsion when the fovea was located below the horizontal line at the lower edge of the optic disc. We considered the eye to be in intorsion, when the fovea was located above the horizontal line passing through the center of the optic disc 27 . Physiological torsion was defined by the fovea laying in the area between the center and the lower edge of the optic disc.…”

patients with acquired adult-onset strabismus mainly present with binocular diplopia. Although cranial nerve palsies are reportedly the most common cause of binocular diplopia in adults, thyroid disease can also cause diplopia. In patients with thyroid-associated ophthalmopathy, upper lid retraction and proptosis are the most common initial findings, but diplopia could be the first manifestation. So far, there has been little information on the diagnostic value of thyroid autoantibodies in patients with strabismus. Therefore, we examined adults with acquired binocular diplopia from 2008 to 2016 and evaluated the presence of thyroid autoantibodies and the relationship between thyroid autoantibody status and clinical characteristics in adults with acquired binocular diplopia. thyroid autoantibody tests were performed for all patients, unless other causes of diplopia were identified. Fifty one (39%) of 132 patients were positive for thyroid autoantibodies. In the thyroid autoantibody-positive (TAb+) group, microsomal autoantibodies, thyroid-stimulating hormone receptor antibodies, thyroglobulin antibodies, and thyroid-stimulating antibodies were observed in 30, 27, 12, and 7 patients, respectively. the vertical deviation and grade of duction limitation were greater in the tAb+ group. the presence of ocular torsion was 15.5% and 39.5% in the TAb− and tAb+ groups, respectively. Thyroid autoantibody evaluation may be helpful in adults with idiopathic acquired binocular diplopia.

“…Various disorders involving the cyclovertical extraocular muscles could result in cyclodeviation, including traumatic or ischemic superior oblique palsy (SOP), secondary strabismus caused by thyroid-associated orbitopathy, and skew deviation from brainstem lesions (1)(2)(3). Other possible causes are primary oblique muscle overaction with A-or V-pattern strabismus (4)(5)(6), inferior oblique paresis (7) or other vertical muscle palsies (8) from oculomotor nerve palsy, Brown syndrome (9), iatrogenic postoperative cyclotorsion from retrobulbar anesthesia (10,11), and surgically induced cyclotorsion from macular translocation surgery (12), scleral buckling procedure (13), or consecutively from prior strabismus surgery (14)(15)(16)(17). The resulting torsional misalignment may cause severe debilitating symptoms of cyclodiplopia to these patients in the acute state (18), which cannot be alleviated by any prism or orthoptic treatment, except for omitting vision entirely by occlusion or through sensory adaptation mechanisms (19) in chronic conditions.…”

A simple marking system for accurate intraoperative monitoring and adjustment of cyclotorsion strabismus surgery

et al. 2023

Ocular cyclotorsion is treatable only with surgery. The surgical procedure must be tailored individually to the specific etiologies causing the horizontal and vertical strabismus and its torsional components. An adjustable surgical approach is often used for postoperative or intraoperative adjustments. However, the methods currently used have some limitations. In this study, we propose a simple intraoperative marking system for all cyclotorsion correction surgery. The proposed marking system used three sets of surface markers: external horizontal markings, ocular horizontal markings, and surgical torsion markings, drawn in sequence. We retrospectively analyzed the surgical results using this novel marking system in this single-center, single-surgeon study. Fifteen patients with cyclotorsion who underwent treatment using the proposed marking system as an intraoperative aid between August 2019 and August 2021 were included. The medical charts were thoroughly reviewed, and the pre-and postoperative subjective and objective cyclotorsion were analyzed. Among the study subjects (10 males, 5 females; age range: 6–89 years), 13 had excyclotorsion and 2 incyclotorsion. Preoperative mean net subjective cyclotorsion measured by the double Maddox rod (DMR) test was 6.0° (standard deviation: 10.8°) and mean net disc-to-fovea angle (DFA) was 20.23° (13.21°). The postoperative net DMR and DFA were 0.2° (2.1°) and 14.09° (5.97°), respectively. The mean absolute net DMR and DFA being treated were 9.8° (4.8°) and 9.76° (4.61°). Overall, the proposed intraoperative marking system is a simple and quantitative method to assess, monitor, and adjust the torsional aspect for all strabismus surgeries.
