简要总结
Macular edema is a condition in which there is swelling in the macula, the part of the retina that gives you your best vision. This swelling can cause your vision to decline. When diagnosed early and treated, you vision usually can be preserved. However, if the swelling goes untreated for a long time, it can cause permanent vision loss.
We think that the three eye drop regimens in this study, difluprednate, difluprednate plus nepafenac, and prednisolone acetate plus nepafenac, might be effective in treating uveitic macular edema. Patients who enter this study are randomized to one of the three regimens and followed for 24 weeks.
详细描述
Trial: Randomized 3 arm (1:1:1) parallel design comparative effectiveness trial
Stratification: Systemic corticosteroid/immunosuppressive therapy vs. none
Treatments: 1) difluprednate 0.05% 2) combination therapy of prednisolone acetate 1% with nepafenac 0.1% 3) combination therapy of difluprednate 0.05% with nepafenac 0.1%
Masking: Unmasked treatment administration; masked outcome assessment (evaluation of OCT and visual acuity)
Follow-up: 2, 4, 6, 8, and 24 weeks

研究组 & 干预措施
Difluprednate
Difluprednate 0.05% ophthalmic emulsion 4 times a day until Week 4, then decrease according to protocol (if resolution of edema at 4 weeks, decrease to 1 drop per day until Week 6, then stop; if not resolved, continue at 4 times a day until 6 weeks and then decrease to 1 drop per day until Week 8 if resolved, then stop). If macular edema not resolved (or reoccurs) by Week 8, treat per best medical judgement.
干预措施: Difluprednate (Drug)
Nepafenac plus Prednisolone acetate
Nepafenac 0.1% 3 times a day until resolution; prednisolone acetate 1% 4 times a day until Week 4, then decrease according to protocol (if resolution of edema at Week 4, decrease to 1 drop per day until Week 6, then stop; if not resolved, continue at 4 times a day until Week 6, then decrease to 1 drop per day until Week 8, then stop). If macular edema not resolved (or reoccurs) by Week 8, treat per best medical judgement.
干预措施: Nepafenac (Drug)
Nepafenac plus Prednisolone acetate
Nepafenac 0.1% 3 times a day until resolution; prednisolone acetate 1% 4 times a day until Week 4, then decrease according to protocol (if resolution of edema at Week 4, decrease to 1 drop per day until Week 6, then stop; if not resolved, continue at 4 times a day until Week 6, then decrease to 1 drop per day until Week 8, then stop). If macular edema not resolved (or reoccurs) by Week 8, treat per best medical judgement.
干预措施: Prednisolone acetate (Drug)
Difluprednate plus Nepafenac

If macular edema not resolved (or reoccurs) by Week 8, treat per best medical judgement.
