Friedrich Nietzsche developed dementia at the age of 44 years. It is generally assumed that the cause of his dementia was neurosyphilis or general pareisis of the insane (GPI). Others have proposed frontal-based meningioma as the underlying cause. We have reviewed Nietzsche's medical history and

BACKGROUND Leber congenital amaurosis, caused by mutations in RPE65 and LRAT, is a severe form of inherited retinal degeneration leading to blindness. We aimed to assess replacement of the missing chromophore 11-cis retinal with oral QLT091001 (synthetic 9-cis-retinyl acetate) in these

Restoring vision in inherited retinal degenerations remains an unmet medical need. In mice exhibiting a genetically engineered block of the visual cycle, vision was recently successfully restored by oral administration of 9-cis-retinyl acetate (QLT091001). Safety and visual outcomes of a once-daily
