Brief Summary
Since 2004, intravitreal injection of Avastin, Lucentis, and Macugen for wet age-related macular degeneration, retinal vein occlusion, and diabetic macular edema are being administered in the United States at increasing rates. A 2010 study showed that in Canada and the incidence of injections grew 8 fold from 2005 to 2007 to 25.9 injections per 100,000 citizens. (Campbell 2010) In 2009, in the United States, over 1 million intravitreal injections were administered to Medicare beneficiaries. (Wykoff 2011) In the year 2011, the four doctors in my retina group administered a total of 6,494 intravitreal injections; in 2010, we administered 5021 intravitreal injections. Even though intravitreal injections are commonly administered, the optimal method of anesthetizing the eye prior to injection has yet to be determined. Some physicians use an anesthetic drop, some a soaked cotton pledget, some use an anesthetic gel and some use subconjunctival injected anesthetic. In 2009, the last time the Procedures and Trends Survey (PAT) (Mittra 2009) conducted by the American Society of Retina Specialists (the largest retina society in the world) asked about anesthetic methods for administering intravitreal injections, the following response was given by the 433 respondents:
- Topical anesthetic drop: 21.48%
- Topical viscous anesthetic: 23.33%
- Topical anesthetic \& soaked cotton-tip or pledget: 29.79%
- Subconjunctival injection of anesthetic: 24.02%
- Other: 1.39% An editorial in 2011 in the journal Retina, discusses the lack of good studies assessing optimal anesthetic prior to intravitreal injections. (Prenner 2011).

Outcome Measures
Primary Outcomes (1)
Number of Participants Who Preferred Subconjunctival Anesthetic at the Third Follow-up Visit
Participants received anesthetic over several treatment visits. They were allowed to change there preference at each visit. The final outcome was the preference indicated at the third follow-up visit.
up to 6 months
Secondary Outcomes (2)
Number of Participatns With Level 10 Pain on Wong-Baker Pain Scale In Subconjunctival Eye At Time of Intravitreal Injection
24 hours
Likert Like Pain Scale Number of Participants Who Said the Topical Eye Hurt Much More Than the Subconjunctival Eye at Time of Intravitreal Injection
24 hours
