Abstract
To determine if topical gel is superior to subconjunctival injection of lidocaine in relieving pain of intravitreous injection of corticosteroid. Randomized clinical trial. One hundred patients receiving intravitreous injection of triamcinolone. INTERVENTIONAL PROCEDURE: Topical lidocaine 2% gel and subconjunctival lidocaine 2% injection. Analog pain score assessment, conducted by technician masked to treatment. There was no statistically significant difference in pain scores between the treatment groups (P = .1). The effective relief of pain with lidocaine for intravitreous injection is independent of its mode of application (gel vs subconjunctival injection).
