Posterior pole retinal tears following blunt ocular trauma

American Journal of Ophthalmology Case Reports, 2020
Purpose: Posterior pole retinal tears occur rarely following blunt trauma. We describe a case of traumatic macular tears, without concurrent peripheral retinal tears or holes. Observations: A 17-year-old patient presented to our emergency unit with blunt

Retinal Pigment Epithelium Tear [PDF]

Current Ophthalmology Reports, 2014
Retinal pigment epithelium tear is a potentially vision threatening complication of retinal pigment epithelial detachment associated with neovascular age-related macular degeneration. Retinal pigment epithelium tear has been reported to occur spontaneously and after treatment with anti-vascular growth endothelial factor agents.

Myopia as a risk factor for subsequent retinal tears in the course of a symptomatic posterior vitreous detachment

BMC Ophthalmology, 2017
Background Retinal tears complicating the course of a posterior vitreous detachment (PVD) may be unique or multiple, and when multiple they may occur simultaneously or subsequently at different moments in the evolution of a PVD.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...
