The Thyroid Gland01:23

The Thyroid Gland

7.8K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones

5.8K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

8.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Muscles of the Eye01:20

Muscles of the Eye

4.6K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

3.9K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.3K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Summary
This summary is machine-generated.

Some thyroid eye disease (TED) patients present with progressive fibrosis, not inflammation. This atypical presentation in older individuals suggests unique disease mechanisms requiring further investigation.

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Immunology

Background:

  • Thyroid eye disease (TED) typically follows an inflammatory phase, then a fibrotic phase.
  • This natural history is characterized by self-remitting disease progression.

Observation:

  • We report 3 cases of TED presenting primarily with severe, progressive fibrosis.
  • These patients showed no signs of prior active inflammation and were older than typical TED patients.
  • Two cases developed recalcitrant dysthyroid optic neuropathy.

Findings:

  • This subgroup of TED patients exhibits an atypical disease course, diverging from the usual inflammatory progression.
  • The disease progression in these cases was severe and characterized by fibrosis.
  • Age may play a role in this variant of TED.

Implications:

  • The pathophysiology of this atypical TED may involve heterogeneity in orbital fibroblast function.
  • Further research is needed to understand the mechanisms underlying this fibrotic-predominant TED.
  • Investigating potential links between aging and inflammatory mediators in TED is warranted.
