Matched population comparison of visual outcomes and patient satisfaction between 3 modalities for the correction of low to moderate myopic astigmatism

Clinical Ophthalmology, 2017
Purpose To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction.

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Pigmented Birthmarks and Spinal Neurofibromas in KRAS Mosaicism—Not to Be Confused With NF1

Pediatric Dermatology, EarlyView.
ABSTRACT We report a child presenting with pigmentary skin lesions and spinal neurofibromas who was diagnosed molecularly with KRAS mosaicism. We review the previous literature of two cases of congenital skin lesions and neurofibromas and spinal nerve root hypertrophy caused by KRAS variants and highlight this presentation as an important differential ...

Test and evaluation of the 2.4-micron photorefractor ocular screening system [PDF]

An improved 2.4-m photorefractor ocular screening system was tested and evaluated. The photorefractor system works on the principal of obtaining a colored photograph of both human eyes; and, by analysis of the retinal reflex images, certain ocular ...

Dupilumab Reduces Pruritus in Twins With Sjögren–Larsson Syndrome

Pediatric Dermatology, EarlyView.
ABSTRACT Sjögren–Larsson Syndrome (SLS), now termed ALDH3A2‐syndromic epidermal differentiation disorder (sEDD), is a rare genetic disorder marked by thickened skin, spasticity, and intellectual disability. Intractable pruritus is a nearly universal and debilitating feature of SLS that remains poorly managed by current therapies. We describe 4‐year‐old

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.
