Tenectomy of the superior oblique muscle resulted in complete disappearance of Brown's syndrome in 7 out of 8 children operated on. In view of this, it can be a method of choice in treatment of the syndrome. There was the first clinical case of an additional abnormal attachment of the superior oblique muscle tendon to the sclera. In another patient an abnormal marked vascularization of the tendon identified histologically had the appearance of a muscular structure at the site of the tendon seen at the operation.

Morphometric analysis of extraocular muscles and proptosis by computed tomography in Graves' orbitopathy.

Objective: To assess the prevalence of changes on computed tomography (CT) in Graves' orbitopathy (GO) and to correlate those changes with disease activity, as well as with clinical and biochemical variables.
Materials And Methods: This was a retrospective study, conducted at a tertiary hospital, of clinical, biochemical, and imaging data from consecutive patients with GO who underwent at least one orbital CT scan between July 2012 and December 2020. A single observer quantified the thickness of the extraocular muscles and the degree of proptosis.
The trochlea for the intermediate tendon of the digastric muscle: a review.

This review explores the novel perspective that the intermediate tendon of the digastric muscle may function as an anatomical trochlear pulley system within the human body, challenging the traditional understanding of trochlear systems. While widely recognized trochlear units include structures like the medial part of the humerus and the superior oblique muscle of the orbit, the review focuses on the unique anatomical arrangement of the intermediate tendon of the digastric muscle in connection with the anterior and posterior bellies of the digastric muscles. Despite current debates within the anatomical community about labeling the digastric muscles as having a trochlea, this paper delves into the scientific definition of a trochlear pulley system, presenting the intermediate tendon of the digastric muscle as a potential trochlea.

This study presents TOM500, a comprehensive multi-organ annotated orbital magnetic resonance imaging (MRI) dataset. It includes clinical data, T2-weighted MRI scans, and corresponding segmentations from 500 patients with thyroid eye disease (TED) during their initial visit. TED is a common autoimmune disorder with distinct orbital MRI features.

Purpose: To study the feasibility and value of assessing patients with Graves' orbitopathy (GO) in 99mTc-diethylenetriamine pentaacetic acid (DTPA) orbital single photon emission computed tomography/computed tomography (SPECT/CT) with extraocular muscle maximum standardized uptake value (SUVmax).
Methods: A total of 235 patients underwent 99mTc-DTPA orbital SPECT/CT, including 176 patients with GO and 59 patients with Graves' disease (GD) as controls. The SUVmax of extraocular muscles, including right medial rectus muscle (RMR), right lateral rectus muscle (RLR), left medial rectus muscle (LMR), left lateral rectus muscle (LLR), was compared between groups, correlation analyses with clinical activity scores (CAS) and serological indices was performed, and the diagnostic efficacy was evaluated using receiver operating characteristic curves.
Trochlear Nerve Decompression by Endoscopic Suboccipital Supracerebellar Infratentorial Approach: A Technical Note: 2-Dimensional Operative Video.

Department of Neurological Surgery, The Ohio State University, Columbus, Ohio, USA.
Background And Importance: Superior oblique myokymia (SOM) is a rare, acquired aberration of the innervation of the superior oblique, resulting in episodic monocular contraction of the superior oblique muscle characterized by intermittent rotatory eye movement causing diplopia and oscillopsia. Several treatment modalities have been described to treat SOM, including medication and surgical interventions. There is a paucity of reports describing microvascular decompression (MVD) of the trochlear nerve near the root entry zone for the treatment of a neurovascular conflict.
