To access its online representations, visual working memory (VWM) relies on a pointer-system that creates correspondence between objects in the environment with their memory representations. This pointer-system allows VWM to modify its representations using a process called updating. When the pointer is invalidated, however, VWM triggers a process called resetting in which the no longer relevant representation and pointer are replaced.

Background: Central retinal vein occlusion and cilioretinal artery occlusion are rare but serious ocular conditions that can lead to significant visual impairment. While few cases of central retinal vein occlusion and cilioretinal artery occlusion have been individually reported, concurrent occlusion of both vessels is extremely rare, particularly in younger patients without traditional vascular risk factors. We present the first reported case of simultaneous central retinal vein occlusion and cilioretinal artery occlusion in a young female patient associated with short-term use of progestin-only oral contraceptives (OCPs).

Aim: Leber hereditary optic neuropathy (LHON) predominantly manifests during adolescence or young adulthood, resulting in sudden and profound vision loss in individuals who previously had normal vision. This abrupt change significantly impacts daily life, necessitating emotional support, counseling and low-vision rehabilitative services to help affected individuals cope with the shock and adapt to their residual vision. The psychosocial burden of dealing with vision loss extends beyond the individuals directly affected by LHON, affecting matrilineal relatives who face the dual challenges of grieving for their loved one's vision loss and managing their own uncertainty about potential vision loss and its familial implications.
