Visual pathway function and structure in Wolfram syndrome: patient age, variation and progression.

ABSTRACT:

Background/aims

To report alterations in visual acuity and visual pathway structure over an interval of 1-3 years in a cohort of children, adolescents and young adults who have Wolfram syndrome (WFS) and to describe the range of disease severity evident in patients with WFS whose ages differed by as much as 20 years at first examination.

Methods

Annual, prospective ophthalmological examinations were performed in conjunction with retinal nerve fibre layer (RNFL) analysis. Diffusion tensor MRI-derived fractional anisotropy was used to assess the microstructural integrity of the optic radiations (OR FA).

Results

Mean age of the 23 patients with WFS in the study was 13.8 years (range 5-25 years). Mean log minimum angle resolution visual acuity was 0.66 (20/91). RNFL thick
