Spontaneous Decompression Fracture in Thyroid Eye Disease.

Area of Science:

• Ophthalmology
• Endocrinology
• Trauma Surgery

Background:

• Graves' orbitopathy is an autoimmune condition affecting the eye muscles and tissues.
• Orbital fractures typically result from direct physical trauma.
• Spontaneous orbital fractures are exceedingly rare in medical literature.

Observation:

• A 44-year-old female with a history of Graves' orbitopathy presented with acute left periorbital swelling, ecchymosis, and subconjunctival hemorrhage.
• The patient reported no history of trauma, with both patient and her mother denying any inciting event.
• CT imaging revealed a left orbital blowout fracture with enlarged extraocular muscles.

Findings:

• The patient sustained a spontaneous orbital fracture, a highly unusual occurrence.
• The enlarged extraocular muscles associated with Graves' orbitopathy may predispose to such fractures.
• The mechanism suggests a possible link between underlying orbital pathology and traumatic-like injury.

Implications:

• This case underscores the potential for unusual complications in patients with Graves' orbitopathy.
• It suggests that spontaneous orbital fractures, though rare, should be considered in the differential diagnosis.
• Further investigation may elucidate the biomechanical factors contributing to spontaneous orbital fractures in specific conditions.
