TINU Syndrome in Bilateral, Intermediate, or Posterior Uveitis — After Systemic Corticosteroids Did Not Achieve Prompt Resolution

Tubulointerstitial nephritis and uveitis syndrome (TINU) frequently involves the eye in the form of bilateral, intermediate, or posterior uveitis. These presentations require systemic therapy — and when initial corticosteroid treatment does not promptly resolve ocular inflammation, a structured next-line protocol applies.

Why Escalation Is Needed

The first-line approach for bilateral, intermediate, or posterior uveitis in TINU syndrome is systemic corticosteroids, with local steroid injections reserved for rare unilateral cases. Progression to this protocol is indicated when that treatment fails to achieve prompt resolution of ocular inflammation.

Clinical Scenario

This protocol addresses TINU syndrome presenting with bilateral uveitis, intermediate uveitis, or posterior uveitis in patients whose ocular inflammation has not responded adequately to corticosteroid therapy.

Treatment Approach (Summary — Partial)

A steroid-sparing immunomodulatory strategy is introduced, with the aim of achieving and sustaining ocular quiescence over an extended period before any withdrawal of treatment is considered. The complete regimen, sequencing, and agent selection are detailed in the full protocol.

Treatment Goal

Maintenance of ocular quiescence for at least 12–24 months.

In bilateral, intermediate, or posterior disease, systemic corticosteroids are typically required with the option for local steroid injections reserved for the rare unilateral case.

We institute IMT as required for improved anti-inflammatory control, to reduce recurrences upon steroid tapering, or to reduce unwanted steroid-related adverse effects, and seek to maintain quiescence for at least 12–24 months before withdrawing treatment.
