Ocular involvement in pediatric Behçet's disease: is it different than in adults? (a short case series and mini review).

BACKGROUND: Pediatric Behçet's disease (PBD) is rarer than BD and can be a challenging diagnosis as clinical picture may be incomplete. As in adult patients, sight-threatening ocular manifestations may lead to diagnosis. In this study, we aimed to report a series of cases of PBD with ocular manifestations and provide a review of the literature. METHODS: Retrospective case series of PBD patients with ocular manifestations. Demographic, ophthalmological and systemic data at presentation and during follow-up were collected and analyzed. RESULTS: Four patients, aged 13.0 ± 2.9 years (9-16) were included. Posterior uveitis with retinal vasculitis, papillitis and macular edema was present in all patients, with associated anterior uveitis in 2 cases. Other features included occlusive vasculitis (2/4) and necrotizing retinitis (2/4). All patients were improved by systemic treatments except one patient with severe bilateral optic neuropathy. Ocular manifestations were the presenting symptoms in 3/4 cases. CONCLUSION: Ocular manifestations and systemic associations of PBD are comparable to those encountered in adult patients. The lack of complains in pediatric patients may lead to a longer diagnosis delay, especially in unilateral uveitis. Aggressive and long-term treatment is mandatory to prevent vision loss and recurrences.

Evaluation of Strabocheck® as an objective measurement method of comitant horizontal strabismus in children undergoing surgery.

The gold standard of angle measurement is the prism alternating cover test (PCT). This method requires cooperation from the child, experience, and presents a significant inter-observer variability. Strabocheck®(SK) is a new simple tool for objective and semi-automated angle measurement. Our purpose is to evaluate Strabocheck® in children undergoing surgery for comitant horizontal strabismus. The study population was divided into 3 groups: infantile esotropia, partially accommodative esotropia and intermittent exotropia. The primary endpoint was the agreement between Strabocheck®and the PCT. A total of 44 children were included prospectively. The correlation between the angle measured by the PCT and the angle measured by SK was strong (R = 0.87). The mean absolute difference in the angle measured by the two methods was Δ = 11.9+/- 9.8 diopters. The Bland-Altman plot shows a 95% interval limit between -30.0 [-34.4; -25.6] and 31.0 [26.7; 35.4] diopters. SK is an interesting tool to evaluate the angle of strabismus in children. However, the residual discordance between PCT and SK leads us to question the real value of the angle, which can only be approximated. A better clinical experience of this new tool in relation to the clinical condition and the PCT will allow to have a more accurate idea on the true angle and will probably help the surgeon to adapt this procedure.
