Topical gel vs subconjunctival lidocaine for intravitreous injection: a randomized clinical trial.
OBJECTIVE
To determine if topical gel is superior to subconjunctival injection of lidocaine in relieving pain of intravitreous injection of corticosteroid.


METHODS
Randomized clinical trial.


METHODS



METHODS
One hundred patients receiving intravitreous injection of triamcinolone. INTERVENTIONAL PROCEDURE: Topical lidocaine 2% gel and subconjunctival lidocaine 2% injection.


METHODS
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).
