Cystoid 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 get bad. When it is diagnosed early and treated, you vision usually can be preserved. However, if the swelling goes untreated for several months, it can cause permanent vision loss. We think that the two eyedrop regimens in this study, difluprednate or nepafenac plus prednisolone, might be effective in treating uveitic macular edema. Patients who enter this study are being randomized to one of the two regimens and are being followed for one month.

Clinical Details

Official title: Difluprednate Versus Nepafenac Plus Prednisolone Acetate for the Treatment of Cystoid Macular Edema Associated With Uveitis

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome: Number of patients with improvement and/or resolution of macular edema

Secondary outcome:

number of patients with resolution of macular edema

number of patients with improvement in macular edema defined as 20% or greater reduction in central subfield thickness by OCT but not resolution

number of patients with intraocular pressure increase greater than 10mmHg over baseline

Number of patients in each group with 2-line improvement in visual acuity

Change in macular central subfield thickness by OCT at 2 weeks

Detailed description: Randomized, observer-masked superiority trial of difluprednate 0. 05% versus nepafenac 0. 1% plus prednisolone acetate 1%. Patients will be randomized at enrollment to either difluprednate 0. 05% 6 times a day or prednisolone acetate 1% 6 times a day plus nepafenac 0. 1% 3 times a day for 1 month. They will undergo repeat examination at 2 weeks post-enrollment (range 12 to 16 days) and at 4 weeks post-enrollment (range 25-35 days). The OCT, visual acuity and intraocular pressure examiner will be masked as to the patient's assignment. The treating physician and patient will be unmasked.


Minimum age: 7 Years. Maximum age: N/A. Gender(s): Both.
