BACKGROUND The optimal site for local anesthetic placement during ultrasound-guided infraclavicular block remains controversial. METHODS Patients were randomized to receive lidocaine 2% 30 mL as a single injection posterior to the axillary artery (n = 51) or a triple injection ideally adjacent to each brachial plexus cord (n = 49). Pinprick sensory and motor block (3 = no block, 0 = complete ...

intravitreal injection is the most common approach for drug delivery to the posterior segment in humans. however, following the injection, drugs are rapidly eliminated from the vitreous, with half-lives up to a few days. depending on the rate of clearance from the vitreous, large boluses and frequent administrations may be required to ensure therapeutic levels over an extended period of time. m...

We report a case of posterior scleritis effectively managed with intravitreal bevacizumab. A 71-year-old woman was diagnosed with posterior scleritis. Although she was initially treated with systemic steroids, her clinical presentation deteriorated. She was then treated with a single intravitreal injection of bevacizumab and aqueous humor collection. The aqueous level of vascular endothelial gr...
