A Study of the Safety and Efficacy of a New Treatment for Non-Infectious Intermediate or Posterior Uveitis

This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of non-infectious intermediate or posterior uveitis.

Percentage of patients with Vitreous Haze Score of Zero at Week 8. Score is based on standardized scale of 0 to +4 where 0 equals no inflammation and +4 equals optic nerve head not visible (severe).

Percentage of Patients with at least a 15-letter improvement in BCVA at Week 8 from Baseline. BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). The higher the number of letters read correctly, the better the vision (or visual acuity). An improvement in the number of letters read means that the vision has improved.

Percentage of Patients With at Least a 10-Point Improvement in the National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25)Score

Percentage of patients with at least a 10-Point Improvement in the NEI-VFQ-25 over-all composite score at Week 8 from Baseline. The NEI-VFQ-25 consists of 25 vision-targeted questions plus one general health question resulting in a score of 0-100 (100 represents best functionality).

Inclusion Criteria: 18 years or older with a diagnosis of chronic intermediate uveitis in at least one eye Exclusion Criteria: Uncontrolled systemic disease Any active ocular infections
