Upper eyelid retraction after periorbital trauma.

Area of Science:

• Ophthalmology
• Trauma Surgery

Background:

• Periorbital trauma can lead to various ocular complications.
• Upper eyelid retraction is an uncommon sequela of such injuries.

Observation:

• Four patients presented with unilateral upper eyelid retraction after periorbital trauma.
• Trauma mechanisms included blow-out fractures, contusion, and canalicular laceration.
• Symptoms developed days to a month after the initial injury.

Findings:

• Thyroid function tests were normal in all patients.
• Orbital CT revealed superior rectus muscle and superior oblique muscle adhesion in one case.
• Diffuse thickening of the superior rectus muscle and levator complex was noted in another case.
• No specific CT findings were observed in two cases.

Implications:

• Upper eyelid retraction following periorbital trauma may result from superior complex adhesion.
• This finding expands the spectrum of potential complications following orbital injuries.
• Further investigation into the pathophysiology and management of post-traumatic eyelid retraction is warranted.
