Delayed dark adaptation in central serous chorioretinopathy
American Journal of Ophthalmology Case Reports, 2021 Purpose: To evaluate the effect of central serous chorioretinopathy (CSCR) on retinal function using dark adaptation in a human subject, and to follow it through resolution of the disease.

Evaluating Situated Visualization in AR with Eye Tracking [PDF]
arXiv, 2022 Augmented reality (AR) technology provides means for embedding visualization in a real-world context. Such techniques allow situated analyses of live data in their spatial domain. However, as existing techniques have to be adapted for this context and new approaches will be developed, the evaluation thereof poses new challenges for researchers.

Binocular Eye Movements Are Adapted to the Natural Environment [PDF]
The Journal of Neuroscience, 2019 Humans and many animals make frequent saccades requiring coordinated movements of the eyes. When landing on the new fixation point, the eyes must converge accurately or double images will be perceived. We asked whether the visual system uses statistical regularities in the natural environment to aid eye alignment at the end of saccades. We measured the

A Python package for fast GPU‐based proton pencil beam dose calculation
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Custom Ocular Prosthesis for Enucleated Eye: A Case Report
Journal of College of Medical Sciences-Nepal, 2016 The unfortunate loss or absence of an eye may be caused by a congenital defect, irreparable trauma, tumor, sympathetic ophthalmia, or the need for histologic confirmation of a suspected diagnosis.

Small-aperture monovision and the Pulfrich experience: absence of neural adaptation effects. [PDF]
PLoS ONE, 2013 PURPOSE: To explore whether adaptation reduces the interocular visual latency differences and the induced Pulfrich effect caused by the anisocoria implicit in small-aperture monovision. METHODS: Anisocoric vision was simulated in two adults by wearing in

Generalization Through Hand-Eye Coordination: An Action Space for Learning Spatially-Invariant Visuomotor Control [PDF]
arXiv, 2021 Imitation Learning (IL) is an effective framework to learn visuomotor skills from offline demonstration data. However, IL methods often fail to generalize to new scene configurations not covered by training data. On the other hand, humans can manipulate objects in varying conditions.

Pax6 in Collembola: Adaptive Evolution of Eye Regression [PDF]
Scientific Reports, 2016 AbstractUnlike the compound eyes in insects, collembolan eyes are comparatively simple: some species have eyes with different numbers of ocelli (1 + 1 to 8 + 8) and some species have no apparent eye structures. Pax6is a universal master control gene for eye morphogenesis.
