Effect of intracameral epinephrine use on macular thickness after uneventful phacoemulsification.

PURPOSE

To evaluate changes in central macular thickness using optical coherence tomography after uneventful cataract surgery combined with intracameral epinephrine use.

SETTING

Beyoğlu Eye Training and Research Hospital, Istanbul, Turkey.

METHODS

This prospective case series comprised eyes of consecutive patients who had uneventful phacoemulsification and in-the-bag intraocular lens (IOL) implantation between August 2005 and January 2006. The eyes were randomly assigned to 1 of 2 groups. In 1 group, 0.2 mL epinephrine (1:5000 solution) was injected just after the clear corneal incision was created. The other group (control) did not receive epinephrine. Optical coherence tomography was performed in all eyes preoperatively as well as postoperatively at 1 day, 1 week, and 1, 3, and 6 months.

RESULTS

The epinephrine group comprised 73 eyes (73 patients) and the control group, 76 eyes (86 patients). In both groups, the increase in retinal thickness from preoperatively to 1, 3, and 6 months postoperatively was statistically significant (P<.05); the difference was not statistically significant at 1 day or 1 week in either group (P>.05). There were no statistically significant differences between the 2 groups in mean retinal thickness throughout the follow-up (P>.05). Clinically significant macular edema occurred in 3 eyes in the epinephrine group and 3 eyes in the control group.

CONCLUSION

Although epinephrine is a well-known risk factor for central macular edema, intracameral injection of 0.2 mL epinephrine (1:5000) did not increase the risk for central macular edema in eyes with no risk factors that had uneventful phacoemulsification with IOL implantation.
