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.

Intrinsic signal optoretinography of dark adaptation abnormality due to rod degeneration [PDF]
arXiv, 2022 Significance: Multiple eye diseases such as age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa can cause photoreceptor dysfunction. Rod photoreceptors are known to be more vulnerable than cone photoreceptors. Therefore, functional assessment of rod photoreceptors is important for early detection of eye diseases.

Optical Incoherence Tomography: a method to generate tomographic retinal cross-sections with non-interferometric imaging systems [PDF]
Biomed. Opt. Express 11, 4069-4084 (2020), 2020 Optical tomographic cross-sectional images of biological samples were made possible by interferometric imaging techniques such as Optical Coherence Tomography (OCT). Owing to its unprecedented view of the sample, OCT has become a gold standard, namely for human retinal imaging in the clinical environment.

Parameter estimation and model reduction for retinal laser treatment [PDF]
arXiv, 2022 Laser photocoagulation is one of the most frequently used treatment approaches for retinal diseases such as diabetic retinopathy and macular edema. The use of model-based control, such as Model Predictive Control (MPC), enhances a safe and effective treatment by guaranteeing temperature bounds. In general, real-time requirements for model-based control

Choriocapillaris Flow Signal Impairment in Sorsby Fundus Dystrophy [PDF]
arXiv, 2021 Purpose: To quantify choriocapillaris flow alterations in early Sorsby Fundus Dystrophy (SFD) and to investigate the relationship of choriocapillaris flow with the choroidal and outer retinal microstructure. Methods: In this prospective case-control study, 18 eyes of 11 patients with early SFD and 32 eyes of 32 controls without ocular pathology ...
