Surgical results in spinocerebellar ataxia (SCA)

Patients with SCA frequently develop ocular motility abnormalities including nystagmus, abnormal smooth pursuits, dysmetric saccades, divergence paresis and ophthalmoplegia. Incidence of diplopia is higher in SCA type 3. The purpose of this study was to evaluate surgical responses and outcomes...

Improving vision screening access

The purpose of this study was to determine whether providing access to instrument-based screening equipment would increase the total number of high quality age-appropriate vision screenings provided to pre-school aged children. SPOT vision screening was placed in paediatric offices at...
