Recently, there has been an increased number of studies investigating retinal morphology in infantile nystagmus.1–4 Optical coherence tomography (OCT) studies in achromatopsia have shown progressive retinal changes.1 ,2 ,4 Most OCT software limits segmentation to the retinal nerve fibre layer and overall retinal thickness (RT). However, we have shown that outer nuclear layer (ONL), outer segment (OS) and foveal depth (FD) are important measurements in infantile nystagmus.2 ,5 Intraretinal thicknesses (FD, ONL, inner segment (IS) and OS) can be derived using reflectivity-based segmentation using ImageJ1 (figure 1). External limiting membrane (ELM) and inner–outer segment junction (IS/OS) reflectivity changes have been reported in blue cone monochromatism and achromatopsia. However, it is unclear whether nystagmus allows reproducible OCT measurements of …
