Purpose: Eccentric viewing training for macular disease has been performed for > 40 years, but no large studies including control groups have assessed the benefits of this training. The EFFECT (Eccentric Fixation From Enhanced Clinical Training) study is a large randomized controlled trial of 2 types of eccentric viewing training.
Design: Randomized controlled trial.
Participants: Two hundred adults with age-related macular disease.
Methods: Participants were randomized to either of the following: (1) a control group; (2) a group receiving supervised reading support; (3) a group receiving 3 sessions of training to optimize the use of their own preferred retinal locus; or (4) a group receiving 3 sessions of biofeedback training of a theoretically optimal trained retinal locus. All participants received standard low-vision rehabilitation.
Main Outcome Measures: The primary outcome was patient-reported visual task ability measured on the Activity Inventory instrument at goal level. Secondary outcomes included reading performance and fixation stability.
Results: There was no difference between groups on change in task ability ( = 1.48, = 0.22) or on any of the secondary outcome measures. Visual acuity and contrast sensitivity fell in all groups, suggesting that disease progression outweighed any benefit of training.
Conclusions: Eccentric viewing training did not systematically improve task ability, reading performance, or fixation stability in this study. Our results do not support the routine use of eccentric viewing training for people with progressing age-related macular disease, although this training may help people with end-stage disease. Rehabilitation of an inherently progressive condition is challenging.

The contrast sensitivity function (CSF) characterizes visual function, and iswidely used in research on visual perception and ophthalmological disorders. TheCSF describes the lowest contrast level that participants can perceive as afunction of spatial frequency. Here, we present a new method to estimate theneural equivalent of the CSF that describes how a population of neurons respondsto contrast as a function of spatial frequency.

Redo valve-in-valve transcatheter aortic valve replacement (TAVR) confronts anesthesiologists with compounded hemodynamic and neurologic risk. We managed an 85-year-old male with severe mixed prosthetic aortic dysfunction whose pre-procedural transthoracic echocardiogram showed a peak velocity of 3.7 m/s⁻¹, a mean gradient of 24 mm Hg, an effective orifice area of 0.

We review the current state of our knowledge of the neural control of vergence and ocular accommodation in primates including humans. We first describe the critical need for these behaviors for viewing in a three-dimensional world. We then consider the sensory stimuli that drive vergence eye movements and lens accommodation and describe models of the sensorimotor transformations required to drive these motor systems.

Objectives: We aimed to identify the most diagnostically challenging features in first-trimester point-of-care ultrasound (FT-POCUS) images. We also sought to determine the physician image review behaviors associated with increased diagnostic accuracy.
Methods: We conducted a multicenter prospective cross-sectional study in a convenience sample of emergency physicians in the United States and Canada.

Cardiomyopathy often alters left ventricular geometry (LVG), impairing cardiac function. We developed a deep learning (DL) model to estimate left ventricular ejection fraction (LVEF) from echocardiographic images while accounting for LVG variability and assessed prognostic factors across LVG subtypes. For all patients with cardiomyopathy, we computed LV volume on apical two- and four-chamber views processed with novel DeepLabV3+ algorithm and calculate EF using Simpson's method.
