The Relation Between Corneal and Total Astigmatism [PDF]
, 1996 Using computer-assisted videokeratoscopy we measured corneal astigmatism and compared these results over a range of corneal zone diameters with total ocular astigmatism derived by subjective refraction.

Review of the Molecular and Developmental Basis of Myhre Syndrome, Bench Research
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT Myhre syndrome (MS) is a connective‐tissue disorder within the acromelic dysplasia spectrum. It is characterized by congenital craniofacial, skeletal, cutaneous anomalies, respiratory, cardiovascular along with intellectual disability, deafness, and progressive fibrosis.

Framing anatomical variation in anatomy textbooks: Language use and its implications
Anatomical Sciences Education, EarlyView.Text mining of anatomy textbooks shows “abnormal” is the most frequently used descriptor for anatomical variation, reinforcing a binary framing. We advocate for explicit teaching of variation as a spectrum, with consistent, neutral terminology and contextualization (prevalence and functional relevance) to support a more nuanced understanding of ...

JEADV Clinical Practice, EarlyView.ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

Delicate balance: relationship between internal astigmatism and lens astigmatism
, 2021 Due to the lack of equipment for directly measuring crystal morphology, there are few researches on crystal astigmatism.The purpose of this study was to accurately explore the correlation between internal astigmatism and lens astigmatism in patients with

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts
Laser &Photonics Reviews, EarlyView.Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices
Laser &Photonics Reviews, EarlyView.ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.
