Compressive optic neuropathy (CON) in Graves' disease caused by hypertrophy of levator and superior rectus muscles: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25062

Department of Ophthalmology, Osaka Medical College, Osaka, Japan.

Rationale: Enlargemento of the medial rectus is the most predominant factor of compressive optic neuropathy (CON) in Graves' disease. This case report indicates that CON could develop only from the hypertrophic superior levator and superior rectus (SL/SR) muscle in a patient with poorly controlled Graves' disease, and described the possible risk of FT3-thyrotoxicosis with a prominent goiter to develop the current rare case with a review of the literature.

Patient Concerns: A 66-year-old woman undergoing endocrine management of hyperthyroidism with prominent goiter visited the Department of Ophthalmology due to right-eye upper-eyelid retraction. Read More

Radioiodine therapy of Graves' disease.

Q J Nucl Med Mol Imaging 2021 Jun 10;65(2):132-137. Epub 2021 Feb 10.

Clinic of Nuclear Medicine and Molecular Imaging, Imaging Institute of Southern Switzerland, Bellinzona, Switzerland.

Graves' disease (GD), the most common cause of hyperthyroidism, is an autoimmune disease directly caused by circulating autoantibodies that bind and activate the TSH receptor, inducing metabolic activation of the thyroid gland; this may be associated with important cardiac (atrial fibrillation) and ocular (ophthalmopathy) complications. Treating GD with real curative intent implies the full elimination of the functioning thyroid parenchyma using surgery or radioactive iodine therapy (RAI). RAI has been used in humans with hyperthyroidism since 1941, thanks to the pioneering work of a physician (Dr. Read More

Distinctive Features of Orbital Adipose Tissue (OAT) in Graves' Orbitopathy.

Int J Mol Sci 2020 Nov 30;21(23). Epub 2020 Nov 30.

School of Medicine, Cardiff University, Heath Park, Cardiff CF14 4XN, UK.

Depot specific expansion of orbital-adipose-tissue (OAT) in Graves' Orbitopathy (GO) is associated with lipid metabolism signaling defects. We hypothesize that the unique adipocyte biology of OAT facilitates its expansion in GO. A comprehensive comparison of OAT and white-adipose-tissue (WAT) was performed by light/electron-microscopy, lipidomic and transcriptional analysis using ex vivo WAT, healthy OAT (OAT-H) and OAT from GO (OAT-GO).

Challenges in diagnosing coexisting ocular myasthenia gravis and thyroid eye disease.

Muscle Nerve 2021 05 27;63(5):631-639. Epub 2020 Nov 27.

Neuromuscular Center, Neurological Institute, Cleveland Clinic, Cleveland, Ohio, USA.

Ocular myasthenia gravis (OMG) and thyroid eye disease are two autoimmune conditions that have several overlapping clinical features, and these coexist with a small but not insignificant frequency. Segregating these diagnoses is typically straightforward, but, when the two diseases co-occur in the same individual, making a diagnosis of OMG can be very challenging. In this review we address what is known about the coexistence of OMG and thyroid eye disease and we highlight the clinical features that are suggestive of overlapping conditions. Read More
