Asymmetry and/or unilateral GO can impose diagnostic challenges (13) and it is therefore important that awareness for asymmetric GO be raised. Indexed in Web of Science, PubMed, MEDLINE, and Scopus. It is important to note that published studies have used different definitions of asymmetry and/or unilateral GO and this might explain the big variation in reported epidemiology among published data. Given that the pathophysiological mechanisms causing unilateral or asymmetric GO appear to be similar to the well-described bilateral GO, treatment of asymmetric GO is generally the same with bilateral disease and is usually dependent on disease severity. Orbit (2009) 28:342–6. In the same study asymmetry was more prevalent in females and measurements from the right orbit were greater than the left (16). doi: 10.1046/j.1365-2265.1997.2331047.x, 28.

Background and Aims: The synthetic atypical cannabinoid Abn-CBD, a cannabidiol (CBD) derivative, has been recently shown to modulate the immune system in different organs, but its impact in obesity-related meta-inflammation remains unstudied.

The present mini-review summarizes important information for both clinicians and researchers and also provides the impetus for further research. Quality of life in a german graves orbitopathy population. doi: 10.1371/journal.pone.0176064, 37. Autoimmune processes resulting in proliferation of orbital fibroblasts, increased adipogenesis, and extracellular matrix expansion are involved in its pathophysiology (5) and Thyroid Stimulating Hormone (TSH) Receptor Antibodies (TRAb) seem to be a key determinant. showed that a seven-fold higher risk for unilateral GO in hypothyroid or euthyroid subjects, compared with hyperthyroid GO (26). *Correspondence: Grigorios Panagiotou, email@example.com, Front. Normal measurement of orbital structures: implications for the assessment of Graves’ ophthalmopathy. Impact Factor. doi: 10.4158/EP.7.2.110, 41. Clinicians involved in the care of patients with GO need to be able to identify unilateral or asymmetric GO, as timely recognition of asymmetry may expedite referral to specialist services and facilitate further management.

There is no contraindication in regards to any treatment modality including antithyroid drugs, radioactive iodine, and/or total thyroidectomy for mild asymmetric and/or unilateral GO, while in moderate to severe cases radioiodine should be avoided, similarly to bilateral symmetric disease (42).

It has been suggested that unilateral GO may progress to bilateral disease (11) and we have also found that asymmetry was associated with more severe and active GO (12). Ophthalmic Res (1989) 21:73–82. Shorter duration of symptoms (29) and thyroid status might be associated with asymmetry.

It was established in 2010 and is published by Frontiers Media, who was included on Jeffrey Beall's now-defunct list of "potential, possible, or probable predatory publishers". Radiological criteria for asymmetry, such a right-to-left ratio of more than 1.4 in extraocular muscle diameter, as obtained by CT measurements based on normative data, have also been proposed (24).

Moreover, disease severity is assessed similarly to bilateral disease, using clinically evaluated standardized tools, such as CAS (27) and Vision, Inflammation, Strabismus, Appearance (VISA) (28). doi: 10.1089/thy.2007.0302, 33. Furthermore, previous studies have shown associations of asymmetric/unilateral GO with disease activity and severity and it is crucial that large cohorts include patients of different clinical status. Eye (2006) 20:569–73. In specific, small studies have suggested that euthyroid and primarily hypothyroid patients develop more asymmetrical GO (34, 35), which tends to present more mildly. doi: 10.1111/j.1365-2265.2005.02352.x, 9. However, in a recently published retrospective hospital-based report from India, unilateral disease was much higher at 36% and significantly more common among silent presenters compared to the clinically active group (33).

Endocrinol., 17 December 2020 have speculated that asymmetric distribution of antigen or inflammatory processes may be the cause of asymmetrical expansion of orbital contents (13), though this was not explored in any studies so far. More specifically, in everyday clinical practice, unilateral disease needs to be differentiated from other pathologies affecting one eye. Unilateral GO is likewise variably defined as one or more features in one eye without any such manifestations in the other eye (20), proptosis >2 mm in one eye with normal examination of the other eye (25), or proptosis difference between eyes >4 mm, and/or if clinical signs and symptoms of GO found unilaterally (26).
