Strabismus surgery outcomes in Zika syndrome
Reviewed by Fiona Rowe

This study describes the surgical treatment for five children with congenital Zika syndrome and horizontal strabismus. Six-month follow-up outcomes are reported. There were three females and two males with mean age at surgery of 36.4 ±0.9 months. All had history of seizures which were treated with medication. Two had hydrocephalus and ventriculoperitoneal (VP) shunt. All had moderate to severe visual impairment and glasses for significant refractive error. Fundus abnormalities were noted in seven eyes of four children. Four had infantile esotropia and one had infantile exotropia with poor visual attention and bilateral limitation of upgaze. After surgery, all were aligned at four months and four were aligned at six months. One developed bilateral superior oblique overaction and A exo pattern. Four had constricted visual fields which improved postop. Carers reported social and behavioural improvement postop with improved visual contact, attention and posture. The authors conclude that selected patients with Zika syndrome can achieve motor surgical success with visual field expansion and benefits to global development.
