Rapid diagnosis and swift intervention with targeted treatments is essential to reduce the risk of vision-threatening complications in cases of paediatric uveitis, according to Marie-Hélène Errera MD, PhD.
“These cases in children are typically chronic and may result in substantial ocular complications and vision loss if they are not diagnosed and treated appropriately,” she told delegates attending a World Society of Paediatric Ophthalmology and Strabismus (WSPOS) symposium held during the European Society of Ophthalmology (SOE) meeting in Nice, France.
The differential diagnosis of paediatric uveitis is extensive, noted Dr Errera, associate professor of ophthalmology at UPMC Eye Center, Children’s hospital Pittsburgh and at the University of Pittsburgh School of Medicine, Pennsylvania, United States.
As in adult patients, it is important to identify infectious versus non-infectious uveitis as well as anatomic location, since that will have a bearing on prognosis and treatment strategies, she said.
“Of non-infectious causes, juvenile idiopathic arthritis (JIA) is the most common systemic association of paediatric uveitis and accounts for between 35% and 60% of uveitis cases in children,” she said.
Pars planitis is another common idiopathic intermediate uveitis, which predominantly affects children and adolescents, and accounts for up to 28% of paediatric uveitis cases.
“Complications to watch for with pars planitis include cataract, cystoid macular oedema, vitreous opacities, glaucoma, retinoschisis, retinal detachment, epiretinal membrane and optic disc oedema.”
Other autoimmune causes of paediatric uveitis include juvenile sarcoidosis and Blau syndrome, which may also present with joint and eye involvement. Both of these conditions usually present with granulomatous ocular inflammation and can have posterior segment involvement, which is not normally found in JIA-related uveitis, she added.

Toxoplasmosis, caused by the parasite Toxoplasma gondii, is the most common cause of posterior uveitis in children and adults, said Dr Errera. It is normally unilateral and ocular manifestations include retinochoroiditis and retinal vasculitis, which can be challenging to diagnose and treat.
Sarcoidosis, a rare disease characterised by the formation of granulomas in different tissues and organs throughout the body, presents in two distinct forms in children.
“In children under the age of 5 there are usually three features present – a rash, arthritis and uveitis. In older children, the lungs, lymph nodes and eyes are affected,” she said.
Tubulointerstitial Nephritis and uveitis (TINU) is rare and possibly underdiagnosed. It presents as a sudden-onset bilateral AU in older children to young adults.
Topical corticosteroids such as prednisolone or dexamethasone remain the first-line treatment for both acute and chronic anterior uveitis, said Dr Errera, while in severe cases immunosuppressive and biological agents may be used.
The use of anti-TNF treatments such as adalimumab and infliximab may also be proposed in JIA-related uveitis refractory to conventional therapy, but also tocilizumab, abatacept and rituximab, concluded Dr Errera.
