Two different triamcinolone regimens will be assessed in the study: 40 mg injected posteriorly and 20 mg injected anteriorly. There is no indication of which treatment regimen will be better. Although the injection behind the eye is more common than the injection near the front of the eye, the injection near the front of the eye has less risk of injuring the eye. However, it is possible that the injection near the front of the eye may increase eye pressure more frequently. Little is known about which of the two injections decreases macular edema and improves vision more often.
