Purpose: To evaluate the effects of isolated inferior oblique (IO) muscle recession in patients with superior oblique palsy (SOP) and persistent hypertropia in abduction.
Methods: Retrospective review of patients with unilateral SOP who were treated with isolated IO recession by a single surgeon (MCB) between January 2008 and December 2017. We included patients with congenital and acquired fourth nerve palsies, with a hyperdeviation of less than 20 prism diopters in primary position and at least 4 prism diopters in abduction by prism and alternate cover test (PACT) during distance fixation. A minimum follow-up of 4-6 weeks was required. Age at surgery, etiology, presence of head tilt, motor alignment in primary and secondary gaze positions at distance and near using PACT, versions, ductions, and torsion were recorded from the patients' chart.
Results: Seven patients with SOP were included in this study. Four (57.14%) males, with a mean age at presentation of 41.86 years (range: 6-66 years). Mean follow-up was 13.25 months (range: 1.3-52.2 months). A decrease in mean central gaze hypertropia from 11.4 to 1.71 PD was found. A mean contralateral gaze hypertropia that decreased from 22.28 to 5.71 PD and an ipsilateral gaze hypertropia that improved from 5.86 to 1.14 PD were also noted. Torsion had a mean change of 3.4° of incyclodeviation at the final examination.
Conclusions: This study confirms the efficacy of isolated maximal IO recession for the treatment of unilateral SOP that is accompanied by a modest hypertropia of the paretic eye in abduction.

Canine tooth syndrome after frontoethmoidal osteoma surgery: a case report.
Strabismus
January 2025
Poostchi Ophthalmology Research Center, Department of Ophthalmology, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.
: Canine tooth syndrome is a rare condition defined by the simultaneous presence of superior oblique palsy and Brown syndrome, resulting from pathological changes in the trochlear region. This syndrome can develop through various mechanisms, including dog bites, head trauma, infections, inflammation, and scarring. This report highlights its occurrence following sinus surgery for the first time.

January 2025
Frankfurt Institute for Advanced Studies (FIAS), Frankfurt am Main, Germany.
Purpose: Our study presents a virtual reality-based tangent screen test (VTS) to measure subjective ocular deviations including torsion in nine directions of gaze. The test was compared to the analogous Harms tangent screen test (HTS).
Methods: We used an Oculus Go controller and head-mounted-display with rotation sensors to measure patient's head orientation for the VTS.

Article Synopsis
- Synergistic divergence, or type IV Duane syndrome, is a congenital disorder marked by unusual eye muscle control leading to both eyes moving outward when trying to look to one side.
- A case study of a 23-year-old man highlighted his strabismus surgery to address a significant right exotropia and a left head turn developed for better vision since childhood.
- The surgery involved a combination of a 14 mm recession of the right lateral rectus and a 10 mm resection of the right medial rectus, suggesting this approach as an effective treatment for the condition.
Duane retraction syndrome associated with variant of Rubinstein-Taybi syndrome.
Am J Ophthalmol Case Rep
December 2024
University of California, San Francisco, Department of Ophthalmology, USA.
Purpose: This case report describes a child with Duane retraction syndrome (DRS) associated with genetically confirmed Type II Rubinstein-Taybi syndrome (RTS). The purpose is to better understand the ocular manifestations of RTS and further explore the possibility that the neurodevelopmental genetic abnormality in RTS may sporadically impact ocular motor nerves.
Observations: A 2-year-old male with a history of Type II RTS associated with a de novo variant of presented for a comprehensive eye examination, which revealed a left esotropia of 20 prism diopters (PD) in primary gaze with a significant left face turn, mild globe retraction on adduction in the left eye, and abduction limitation consistent with Type 1 DRS in the left eye.
Automated Measurement of Strabismus Angle Using a Commercial Virtual Reality Headset.
Klin Monbl Augenheilkd
December 2024
Department of Ophthalmology, Zurich University Hospital, Zurich, Switzerland.
Current clinical measurements of strabismus angles (SAs) are manual and require a skilled examiner and active cooperation by patients. This results in high interexaminer variability, and clinical use is limited by the availability of trained examiners. An objective and automated procedure, independent of the examiner, would be useful.
