Attention measures of patients with Rett Syndrome need to overcome the challenges in evaluating the oculomotor function using electronystagmography

At the current time, although eye gaze and eye tracking technologies appear to offer the most appropriate access to assessments of attention and communication, there is a condition that must be met: to have an intact oculomotor function. In this issue De Breet et al.5 rightly focus on this condition and investigated oculomotor function in patients with Rett Syndrome using electronystagmography (ENG). Their aim was to improve oculomotor examination in individuals with RTT by evaluating the challenges encountered during ENG examination in females with RTT when compared to healthy, typically developing children, and to propose possible solutions for obtaining more reliable and reproducible oculomotor results when assessing individuals with RTT. Their results indicated that challenges in examination were mainly related to quality of attention and quality of signals. They suggested some adaptations that include reducing the number of electrodes, changing the picture stimuli and bringing them closer, performing observational assessments rather than ENG, and using virtual reality goggles.
