TINU-associated retinal pigment epithelium detachments: a possible novel posterior segment feature.

Purpose: To report a case of tubulointerstitial nephritis and uveitis syndrome (TINU) with novel posterior segment features of bilateral vitritis and retinal pigment epithelial detachments.

Methods: This is an interventional case report with fundus photographs and fluorescein angiograms of a 9-year-old girl presenting with bilateral acute anterior uveitis 4 months after a diagnosis of acute tubulointerstitial nephritis.

Results: Visual acuities remained normal throughout the 6-month period of follow-up. The anterior and posterior uveitis settled, although retinal pigment epithelial detachments persisted and may be related to the underlying disease process in TINU or exogenous steroid treatment, or both.

Conclusions: The idiopathic inflammatory response seen in TINU is traditionally associated with an anterior uveitis. This case demonstrates that there may be more extensive ocular involvement and that posterior uveitis and retinal pigment epithelial detachments may represent emerging features of atypical cases of TINU.
