Abstract
To describe novel findings on fundus autofluorescence (FAF) and high-resolution optical coherence tomography (OCT) in a 27-year-old woman with the Senior-Loken syndrome (SLSN) emphasizing the photoreceptors' cilia appearance in the macula. The patient had renal transplantation early in life and poor visual acuity due to advanced autosomal recessive retinitis pigmentosa. FAF showed diffuse spots of decreased autofluorescence in the mid-periphery and a perifoveal ring of increased autofluorescence suggesting a bull's eye maculopathy. High-resolution OCT revealed a barely detectable inner-outer photoreceptor segment junction in the central macula corresponding to the area inside of the ring of increased autofluorescence, suggesting initial ciliary junction disorganization before photoreceptors death. Non-invasive technologies can monitor central photoreceptors cilliary anatomy enabling early detection of cell disorganization in diseases involving ciliopathy such as the Senior-Loken syndrome are concluded.
