From the Research

Fluocinolone acetonide should be used as an insert, releasing 0.2 μg/day, to treat noninfectious intermediate, posterior, or panuveitis, as it has been shown to significantly reduce uveitis recurrence rates and improve visual acuity. This recommendation is based on the most recent and highest quality study available, which demonstrated the efficacy and safety of the fluocinolone acetonide insert in treating noninfectious uveitis of the posterior segment 2. The study found that the insert significantly reduced uveitis recurrence rates, improved visual acuity, and reduced the need for adjunctive treatments.

Key Considerations

  • The fluocinolone acetonide insert is a promising new therapy for the treatment of severe uveitis, with a sustained drug delivery system that can release the medication for at least 2.5 years 3.
  • The insert has been shown to be effective in reducing uveitis recurrence rates, improving visual acuity, and reducing the need for adjunctive treatments 2.
  • However, the insert is associated with an increased risk of cataract and glaucoma, and patients should be carefully monitored for these potential complications 4, 5.
  • Systemic therapy may be indicated as the initial treatment for many bilateral uveitis cases, but implant therapy is a reasonable alternative, especially for unilateral cases and when systemic therapy is not feasible or is not successful 4.

Patient Selection

  • Patients with noninfectious intermediate, posterior, or panuveitis who have not responded to systemic therapy or have significant side effects from systemic therapy may be candidates for the fluocinolone acetonide insert.
  • Patients with a history of cataract or glaucoma should be carefully evaluated before receiving the insert, as they may be at increased risk for these complications.

Monitoring and Follow-up

  • Patients receiving the fluocinolone acetonide insert should be carefully monitored for potential complications, including cataract and glaucoma.
  • Regular follow-up appointments should be scheduled to assess the effectiveness of the treatment and to monitor for potential side effects.
