Abstract Childhood maltreatment is reportedly associated with atypical gray matter structures in the primary visual cortex (V1). This study explores hypothesis that retinal structures, sensory organs of vision, are brain atypicality and child examines their interrelation. General ophthalmologic examinations, cognitive tasks, imaging, structural magnetic resonance imaging (MRI) were conducted children adolescents aged 9–18 years experiences (CM) typically developing (TD) children. The nerve...

Macular edema is a known side effect of taxane-based anticancer drugs. We retrospectively investigated data from 11 centers between January 2016 and December 2021. Among 14,260 patients, 30 (0.21%) developed macular edema; these, the number cases associated with nab-paclitaxel was 16 (0.43%), significantly higher than paclitaxel or docetaxel (P < 0.01). Visual acuity (VA) retinal choroidal change were examined in 27 follow-up at least 3 months. The patients' mean age 67.2 years; 14 (51.3%)...
