Medically unexplained visual loss in children and young people: an observational single site study of incidence and outcomes

number of patients diagnosed with MUVL, proportion of patients with a history of or present psychological problems, recovery rate, and improvement in visual acuity.ResultsWe identified 85 cases of MUVL (54 females; median age: 9 years (IQR 7-12)). The median duration of follow-up was 1.2 months (IQR 0-4.3). The estimated annual incidence was 3.5% (95% confidence interval 2.9-4.4%). Thirty-three per cent of children had a history of psychiatric disorders, reported a stressful life event, or showed signs of psychiatric disorder at the time of first presentation. The recovery rate was 25%. Median improvement in best-corrected visual acuity from presentation to last appointment was 0.22 (IQR 0.06-0.43) logMAR.ConclusionThe incidence of MUVL is higher and the rate of resolution lower than previously reported. MUVL may be associated with mental health problems. We recommend screening for psychological problems to facilitate access to psychological treatment.
