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 of triamcinolone. 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).
