Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

Logarithmic intensity and speckle-based motion contrast methods for human retinal vasculature visualization using swept source optical coherence tomography [PDF]
We formulate a theory to show that the statistics of OCT signal amplitude and intensity are highly dependent on the sample reflectivity strength, motion, and noise power.

Multimodal Imaging of Isolated Foveal Hypoplasia: A Case Report
Foveal hypoplasia is characterized by the lack of development of a normal fovea. It may be isolated or may occur secondary to ocular conditions. Optical coherence tomography (OCT), fluorescein angiography, fundus autofluorescence, and OCT angiography may

Early Retinal Changes by OCT Angiography and Multifocal Electroretinography in Diabetes
Background: To evaluate the earliest retinal morphological and functional changes in diabetic eyes without or with early signs of diabetic retinopathy (DR). Methods: Twenty-two eyes with no DR (noDR group), 22 eyes with mild DR (DR group), and 18 healthy

ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.
