Can spicules be detected at disc centre in broad-band Ca II H filter imaging data ?

, 2013
We estimate the formation height range contributing to broad-band and narrow-band filter imaging data in Ca II H to investigate whether spicules can be detected in such observations at the centre of the solar disc. We apply spectral filters of FWHMs from

Retrobulbar Structure Visualization With Enhanced Depth Imaging Optical Coherence Tomography

Investigative Opthalmology & Visual Science, 2013
To assess enhanced depth imaging optical coherence tomography (EDI-OCT) visualization of deep posterior pole structures and retrobulbar tissues in myopic eyes and evaluate ocular structural elements that influence this capability.Thirty consecutive myopic eyes (>-6 diopters) from 21 patients were enrolled.

Demographic and Ocular Factors Associated with Suprachoroidal Space Thickness in Healthy Eyes

Ophthalmology Science
Purpose: The suprachoroidal space (SCS) is an emerging route for drug delivery and gene therapy. Here, we analyze demographic and ocular factors associated with SCS visibility and thickness on enhanced-depth imaging OCT (EDI-OCT) in a large cohort of ...
