Non-contact, in-vivo, functional, and structural ophthalmic imaging using multimodal photoacoustic remote sensing (PARS) microscopy and optical coherence tomography (OCT) [PDF]
arXiv, 2021 Early diagnosis of ocular diseases improves the understanding of pathophysiology and helps with accurate monitoring and effective treatment. Advanced multimodal ocular imaging platforms play a crucial role in the visualization of the ocular components and provide clinicians with a valuable tool for evaluating different eye diseases. Here, for the first

A proper protocol for isolation of retinal pigment epithelium from rabbit eyes
Advanced Biomedical Research, 2014 Retinal pigment epithelium (RPE) is a hexagonal monolayer of pigmented cells located between the neural retina and the choroid with an essential role for visual function. So, isolation, propagation and maintenance of their functional integrity of RPE are crucial for research in vitro which next used for cell transplantation.
