1. A method for treating an inflammation-mediated condition of the eye in an individual, comprising:
- implanting into the vitreous of the eye a bioerodible implant comprising a steroidal anti-inflammatory agent and a bioerodible polymer, wherein the implant delivers the agent to the vitreous in an amount sufficient to reach a concentration equivalent to at least about 0.05 μ
g/ml dexamethasone within about 48 hours and maintains a concentration equivalent to at least about 0.03 μ
g/ml dexamethasone for at least about three weeks.
