An elevated threshold for neuroplasticity limits visual gains with treatment of residual amblyopia in older children and adults. Acetylcholinesterase inhibitors (AChEI) can enable visual neuroplasticity and promote recovery from amblyopia in adult mice. Motivated by these promising findings, we sought to determine whether donepezil, a commercially...

Prisms are a noninvasive tool used to manage diplopia in patients, especially when their strabismus is small and comitant. Prisms can be used for horizontal, vertical, or oblique (but not torsional) strabismus. Ground-in prisms provide the best image quality and cosmetic appearance. Fresnel prisms are best for strabismus that is thought to be tempo...

Microtubules are formed from heterodimers of alpha- and beta-tubulin, each of which has multiple isoforms encoded by separate genes. Pathogenic missense variants in multiple different tubulin isoforms cause brain malformations. Missense mutations in TUBB3, which encodes the neuron-specific beta-tubulin isotype, can cause congenital fibrosis of the...
