Cohort study demonstrates improved visual function with botulinum toxin in patients avoiding surgery.
Botulinum toxin injection may represent a minimally invasive alternative in carefully selected patients, particularly those with mild dysfunction or those wishing to avoid surgery. It provides significant improvements in palpebral fissure height and visual function, with fewer side effects and a faster recovery, making it a viable option for early-stage patients or those wishing to avoid surgery. Further studies should explore its long-term effectiveness.
