Kinori M, Pansara M, Mai DD, et al. - Experts aspired to explore whether there is a nasal displacement of the vertical rectus muscles in heavy eye syndrome (HES) and/or sagging eye syndrome (SES) compared with age-matched controls. They reviewed the charts of all individuals with HES or SES diagnosis seen at the University of California San Diego during the years 2008–2016 who had MRI of the brain and orbits. Twenty-four patients (16 with SES and 8 with HES) and 24 age-matched controls have been retrospectively reviewed. The data presented in this work showed a significant nasal displacement of the superior rectus in HES and SES and inferior rectus (IR) in HES. The observed IR nasal displacement in HES is a new finding and can explain the residual hypotropia and/or esotropia following surgical procedures for HES that do not involve the IR.
