Quantification of dexamethasone released from the implants in each sample at different times. One 0.7 mg dexamethasone implant was injected in a test tube filled with 4 ml of different mediums: BSS, SO-1000, SO-5000 and D-68. Samples were obtained at different times: 24 h, 1, 2 weeks and monthly for 12 months. ELISA test was performed to quantify the released drug and reported in ng/mL.
