The Hartmann⁻Shack wavefront sensor is widely used to measure aberrations in both astronomy and ophthalmology. Yet, the dynamic range of the sensor is limited by cross-talk between adjacent lenslets. In this study, we explore ocular aberration meas

Objective Lesions of incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) are associated with disease progression in intermediate age-related macular degeneration (AMD). However, the corresponding functional impact of these precurs

OBJECTIVES/GOALS: The trabecular meshwork (TM) and Schlemm’s canal (SC), located within the iridocorneal angle (ICA), form the main outflow pathway and a major target for glaucoma treatments. We characterized the human ICA in vivo with Optical Cohe

Intraocular pressure (IOP) is the only modifiable risk factor for glaucoma progression, and many treatments target the trabecular meshwork (TM). Imaging this region in vivo is challenging due to optical limitations of imaging through the cornea at hi

Purpose The retinal circulation regulates blood flow through various internal and external factors; however, it is unclear how locally these factors act within the retinal microcirculation. We measured the temporal and spatial variability of blood ve

We have recently introduced a digital micromirror device for optical wavefront sensing with high dynamic range and flexibility. Here, we report on the wavefront reconstruction accuracy in different scenarios and for sensing of ocular aberrations.

An Analytical and Experimental Comparison of the Integrated Stiles-Crawford Effect of the First Kind
Publikováno v:
Frontiers in Optics + Laser Science APS/DLS.
The Stiles-Crawford effect of the first kind in normal viewing conditions integrated over a full pupil differs from the decay rate obtained with different pupil sizes, explained by the absorption across the photoreceptor cones.

A gradual drop in visibility with obliquely incident light on retinal photoreceptors is namely described by the Stiles-Crawford effect of the first kind and characterized by a directionality parameter. Using a digital micromirror device in a uniaxial

The common Hartmann–Shack wavefront sensor makes use of a lenslet array to sample in-parallel optical wavefronts. Here, we introduce a Hartmann–Shack wavefront sensor that employs a digital micromirror device in combination with a single lens for
