Sequential presentation of bilateral Brown syndrome

Area of Science:

• Ophthalmology
• Strabismus Research

Background:

• Brown syndrome is an uncommon condition affecting eye movement, typically unilateral.
• It involves restricted elevation in the adducted eye position, confirmed by forced duction testing.
• Bilateral presentation occurs in approximately 10% of cases, sometimes with asynchronous onset.

Observation:

• A case of bilateral Brown syndrome is presented.
• The left eye was initially affected by congenital Brown syndrome and surgically treated.
• The right eye subsequently developed Brown syndrome within one year of the left eye surgery.

Findings:

• The study details a rare instance of sequential bilateral Brown syndrome.
• The development of Brown syndrome in the second eye occurred without an apparent cause post-surgery.
• This suggests potential underlying mechanisms or predispositions in bilateral cases.

Implications:

• This case expands the understanding of Brown syndrome's bilateral presentation.
• It underscores the importance of monitoring for contralateral involvement, even after successful treatment.
• Further research into the etiology of asynchronous bilateral Brown syndrome is warranted.
