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