Safety and Efficacy of Difluprednate 0.05% for the Treatment of Anterior Uveitis
October 15, 2012 updated by: Alcon Research
A Phase 3 Multicenter, Randomized, Double-Masked Study of the Safety and Efficacy of Difluprednate 0.05% Ophthalmic Emulsion Compared to Prednisolone Acetate 1% Ophthalmic Suspension in the Treatment of Endogenous Anterior Uveitis
The purpose of this study was to demonstrate that difluprednate 0.05% (Durezol) dosed 4 times daily is noninferior to prednisolone 1% (Pred Forte) dosed 8 times daily for the treatment of endogenous anterior uveitis.

|
The following symptoms were each graded by the subject according to a 0-100 visual analog scale (VAS) using a mark on a 100 mm line (0 = absent, 100 = maximal): eye pain, photophobia, blurred vision, and lacrimation.
The total symptom score was calculated as the sum of the 4 individual symptom scores.

Peripheral synechia was graded by the combined number of clock hours affected (0 = absent; 1 = < 3 hrs; 2 = 3-6 hours; 3 = > 6 hours).
The total sign score was calculated as the sum of the 5 individual sign scores, the anterior chamber cell grade and the anterior chamber flare grade.
The minimum/best total sign score was 0, and the maximum/worst total sign score was 23.
