A 58-year-old man presented with a complaint of subjective visual field loss on the right side and hypertensive emergency. Examination revealed a right homonymous hemianopia. Computed tomography imaging revealed an acute stroke of the left lateral geniculate body. A few months later, automated perimetry revealed characteristic visual field changes associated with this lesion. In this report, the anatomy, pathophysiology, clinical findings, and previously reported etiologies of lateral geniculate body lesions are reviewed.

A membrane-targeted photoswitch restores physiological ON/OFF responses to light in the degenerate retina.

The lack of effective therapies for visual restoration in Retinitis pigmentosa and macular degeneration has led to the development of new strategies, such as optogenetics and retinal prostheses. However, visual restoration is poor due to the massive light-evoked activation of retinal neurons, regardless of the segregation of visual information in ON and OFF channels, which is essential for contrast sensitivity and spatial resolution. Here, we show that Ziapin2, a membrane photoswitch that modulates neuronal capacitance and excitability in a light-dependent manner, is capable of reinstating, in mouse and rat genetic models of photoreceptor degeneration, brisk and sluggish ON, OFF, and ON-OFF responses in retinal ganglion cells evoked by full-field stimuli, with reactivation of their excitatory and inhibitory conductances.

Objective: The field of surgery is highly visual and technical. Yet, there is a paucity of data evaluating how a mandatory visual arts-based workshop may benefit surgical trainees. We report upon the feasibility of and short-term outcomes of a novel, visual art-based curriculum for surgery residents.

Purpose: While surgeons agree that perioperative field blocks should be performed for open inguinal hernia surgery, there lacks consensus in the minimally invasive context. Prior small-scale randomized trials study pain scores only up to 24 h postoperatively. Thus, we sought to investigate the analgesic benefits of a bupivacaine transversus abdominis plane (TAP) block in the first 4 postoperative days.

Diabetic macular edema (DME) is a significant cause of vision loss. The development of peripheral non-perfusion (PNP) might be associated with the natural course, severity, and treatment of DME. The present study seeks to understand the predictive power of central macular changes and clinico-demographic features for PNP in patients with clinically significant DME.

Sphenoid wing meningiomas (SWM) frequently compress structures of the optic pathway, resulting in significant visual dysfunction characterized by vision loss and visual field deficits, which profoundly impact patients' quality of life (QoL), daily activities, and independence. The objective of this study was to assess the impact of SWM surgery on patient-reported outcome measures (PROMs) regarding postoperative visual function. The Visual Function Score Questionnaire (VFQ-25) is a validated tool designed to assess the impact of visual impairment on quality of life.
