The aim of this study is to evaluate if patients receiving a steroid (triamcinolone acetonide) combined with local anesthesia and antibiotic following retina surgery have better postoperative pain control those receiving local anesthesia and antibiotic alone.

Primary Outcome Measures:
  • Subjective pain levels on a 10. scale questionnaire [ Time Frame: Post operative day 1 ] [ Designated as safety issue: No ]
    The primary Outcome Measure of this study is to compare pain levels on postoperative day 1 in patients receiving triamcinolone acetonide with retrobulbar anesthesia versus retrobulbar anesthesia alone.

Secondary Outcome Measures:
  • Dosage of pain medication [ Time Frame: Post operative day 1 ] [ Designated as safety issue: No ]
    1. Total amount of oral analgesics taken in the first 24 hours

  • Measurements of ocular motility [ Time Frame: Post operative day 1 ] [ Designated as safety issue: No ]
    2. Effects of the retrobulbar injections on ocular motility

Other Outcome Measures:
  • Long term monitoring of side effects [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    After post-operarative day 1, other meaningful potential side effects will be monitored at standard of care visits in both groups regarding raise in introcular pressure, increased pain levels, wound healing , and infection.

Detailed Description:

Currently, patients undergoing vitreoretinal surgery at the Emory Eye Center and Emory University Hospital receive a injection of local anesthesia behind the eye (retrobulbar) at the start of surgery to minimize discomfort felt during the surgery. At the end of surgery all patients receive a periocular antibiotic and steroid injection. Some patients also receive a retrobulbar injection of local anesthesia (bupivicaine) at the conclusion of surgery in order to decrease postoperative pain and discomfort.

It has been our observation that when the local anesthesia is combined with a steroid (triamcinolone acetonide) in a retrobulbar injection at the conclusion of surgery, patients tend to be pain free for longer intervals then when local anesthesia is used alone. The objective of this study is to evaluate if patients receiving triamcinolone acetonide combined with local anesthesia and antibiotic compared to those receiving local anesthesia and antibiotic alone do better with postoperative pain control.

All eligible patients undergoing vitreoretinal surgery at the Emory Eye Center and Emory University Hospital will be offered enrollment. About 60 patients will be invited to participate in this study. Patients will undergo standard of care surgery. At the conclusion of surgery, patients will receive a retrobulbar antibiotic and anesthetic as standard of care. Half of the patients will receive this mixture plus steroid and the other half will receive this mixture plus saline. On postoperative day 1, patients will be given a questionnaire to assess pain. Pain levels in the two groups will be compared.
