NEIVATECH pilot study: immersive virtual reality training in older amblyopic children with non-compliance or non-response to patching.

Immersive virtual reality (VR) is recently being explored as a therapeutic alternative for the treatment of amblyopia. This pilot study aimed to evaluate the preliminary efficacy, safety, usability and satisfaction obtained with the use of a novel VR system (NEIVATECH) to provide binocular vision training in previously treated older amblyopic children with non-compliance or non-response to patching. A prospective, multicentre, open-label, single-arm, pilot study was conducted in which the intervention under study was 9 h of therapy with the NEIVATECH system, distributed in 18 half-hour sessions spread over 1 month.

Eye Tracking-Based Characterization of Fixations during Reading in Children with Neurodevelopmental Disorders.

An efficient mode of evaluation for eye movements is the use of objective eye tracking systems combined with subjective tests (NSUCO or DEM), which are easily applicable across all age groups and in eye care clinical settings. The objective of this study was to characterize fixations during reading in two groups: a group of children with neurodevelopmental disorders (NDDG, 24 children, age: 6-12 years) and a group of children with oculomotor anomalies but without NDD (OAG, 24 children, age: 6-12 years). The results obtained were compared with those from a control group (CG, 20 children, age: 6-12 years).
