Would a blind subject, on regaining sight, be able to immediately visually recognize an object previously known only by touch? We addressed this question, first formulated by Molyneux three centuries ago, by working with treatable, congenitally blind individuals. We tested their ability to visually match an object to a haptically sensed sample after sight restoration. We found a lack of immediate transfer, but such cross-modal mappings developed rapidly.

Papilledema is a high-risk cause of vision changes in the Emergency Department (ED) and a critical physical examination finding because of its close association with etiologies that may progress to vision loss or death. Syphilis is a rare infectious cause of papilledema, with scarce case reports published showing its ability to develop such sequela. We present a case of a 35-year-old male with a past medical history of newly diagnosed HIV who originally presented to the ED with a rash and rapidly worsening visional changes.

During the last decade, global health security has been threatened by major Ebola virus disease outbreaks in Western Africa (2014 to 2016) and in eastern Democratic Republic of the Congo (2018 to 2020). Particularly in Western Africa, the outbreak initially overwhelmed health care capacity in already fragile health systems. Thousands of survivors were at risk of newly recognized postacute ocular complications, and their need for urgent ophthalmic care challenged national vision health systems with scarce eye care services.
