Ocular History - First Presentation
15-year-old girl
OS : photophobia and tearing since
10 days
Improvement of symptoms with
topical steroids given by the parents
Then also vision blurring, redness
and photophobia of the OD
June 2012 – First Presentation
Visual
acuity 20/50 OD, 20/40 OS
Intraocular pressure : 19 mmHg
OD, 16 mmHg OS
No vitreous or vitreous haze OS
Fundus examination :
unremarkable OS
OD granulomatous anterior uveitis with
fibrinous exudate in the anterior chamber
OS mild non –granulomatous anterior uveitis
with extensive posterior synechiae
Work-up
Chest X-ray : unremarkable
Tuberculin-skin test : negative
Blood cell count : WBC count : 7700/mm3
Hb = 11 g/dl
Syphilis serology : negative
Anti-nuclear antibodies and antistreptolysine O antibodies : negative
HLA B27 typing : negative
First Diagnosis
Idiopathic anterior uveitis
Treatment: intensive steroid drops and
ointment at bedtime (with progressive
tapering), as well as mydriatics
Follow up - Six weeks later
fever, malaise, anorexia and diffuse arthralgia
Work-up: renal insufficiency and proteinuria
Renal biopsy: acute tubulointerstitial nephritis
Ophthalmological examination:
no clinical signs of active uveitis
Laser flare values : 50 ph/ms OD and 46
ph/ms OS
Final diagnosis
Tubulointerstitial Nephritis and Uveitis
(TINU) Syndrome
systemic prednisolone
(starting dose of 1 mg/kg/day)
maintained for 3 months
Follow-up
Four months after TINU syndrome diagnosis,
Recovery of the renal function
Visual acuity : 20/25 OD and 20/32 OS, flare within
normal limits
Slit-lamp photographs show posterior synechiae , that
are more prominent in the left eye
Conclusions
Although TINU syndrome is a rare cause of uveitis, it
should be highly suspected in patients with bilateral
anterior uveitis of sudden onset who are younger
than 20 years.
Urinalysis should be performed in such patients
Uveitis may occur at the same time of, before or after
nephritis
Conclusions
Systemic steroids are usually prescribed to treat renal
disease. However, they may be required to control
anterior uveitis if unresponsive to topical steroids
A close monitoring is helpful for timely detection of
recurrences of ocular inflammation or insidious
chronic anterior uveitis
Posterior synechia are a common complication of
TINU syndrome-associated anterior uveitis
