Visual outcomes in pediatric optic pathway glioma after conformal radiation therapy.

Purpose: To assess visual outcome prospectively after conformal radiation therapy (CRT) in children with optic pathway glioma.

Methods And Materials: We used CRT to treat optic pathway glioma in 20 children (median age 9.3 years) between July 1997 and January 2002.

Skin cooling before periocular botulinum toxin A injection.

Purpose: To determine if skin cooling decreases the pain associated with periocular botulinum toxin A injections.

Methods: In this prospective study, 14 patients given bilateral periocular injections for blepharospasm or wrinkle reduction were included. Prior to the injections, one side received a skin cooling agent and the other side served as the control.
