Internal limiting membrane separation and posterior vitreous hyperreflective dots: novel OCT findings in Purtscher-like retinopathy

open access: yesBMC Ophthalmology
Background Purtscher or Purtscher-like retinopathy is diagnosed by retinal hemorrhages and areas of retinal whitening on fundus examination, as well as a reduction in visual acuity due to microvascular occlusion of the precapillary retinal arterioles. We

Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.

RETRACTED ARTICLE: Verteporfin-induced formation of protein cross-linked oligomers and high molecular weight complexes is mediated by light and leads to cell toxicity

open access: yesScientific Reports, 2017
Verteporfin (VP) was first used in Photodynamic therapy, where a non-thermal laser light (689 nm) in the presence of oxygen activates the drug to produce highly reactive oxygen radicals, resulting in local cell and tissue damage.

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions
