The case is presented on a 4-year-old child with congenital esotropia, limitation of abduction, cross-fixation, and thoracolumbar scoliosis. Genetic testing of ROBO3 gene confirmed the diagnosis of horizontal gaze palsy and scoliosis (HGPSS).DiscussionHGPPS is a rare congenital disorder characterized by absence of conjugate horizontal eye movements and progressive scoliosis developed in childhood and adolescence. We highlight this motility disorder as a part of the differential diagnosis of early childhood esotropia with cross-fixation and limitation of abduction.
