Identification and quantification of fibrotic areas in the human retina using polarization-sensitive OCT.

Biomed Opt Express 2021 Jul 23;12(7):4380-4400. Epub 2021 Jun 23.

Center for Medical Physics and Biomedical Engineering, Medical University of Vienna, Vienna, Austria.

Subretinal fibrosis is one of the most prevalent causes of blindness in the elderly population, but a true gold standard to objectively diagnose fibrosis is still lacking. Since fibrotic tissue is birefringent, it can be detected by polarization-sensitive optical coherence tomography (PS-OCT). We present a new algorithm to automatically detect, segment, and quantify fibrotic lesions within 3D data sets recorded by PS-OCT. Read More

Structural Endpoints and Outcome Measures in Uveitis.

Ophthalmologica 2021 1;244(5):465-479. Epub 2021 Jun 1.

Department of Ophthalmology, University Hospital Bonn, Bonn, Germany.

Most uveitis entities are rare diseases but, taken together, are responsible for 5-10% of worldwide visual impairment which largely affects persons of working age. As with many rare diseases, there is a lack of high-level evidence regarding its clinical management, partly due to a dearth of reliable and objective quantitative endpoints for clinical trials. This review provides an overview of available structural outcome measures for uveitis disease activity and damage in an anatomical order from the anterior to the posterior segment of the eye.
