A new study 1 from Turkey reported that during the acute phase of the COVID-19 infection, the retinal vascularity and perfusion of the retina decreases and the foveal avascular zone (FAZ) expands. The ...

COVID-19 infection may decrease retinal vascularity and perfusion, expanding the foveal avascular zone (FAZ) during the acute phase. Angiotensin-converting enzyme 2 (ACE2) receptors in the retina ...

As a result, the vascular network often appears as fragmented segments. In this paper, we propose a backbone-agnostic Masked Vascular Structure Segmentation and Completion (MaskVSC) method to ...

where x=number of monomers, usually in the thousands. It should be pointed out that when the polyethylene chain is finished growing, two Hydrogen atoms are added to 'cap' (finish) the chain ends.

The retina is a layered structure that lines the inner surface of the eye. It consists of layers of neurons: light-sensitive photoreceptor cells, bipolar cells, horizontal cells, amacrine cells ...

This study demonstrates the critical role of Afadin on the generation and maintenance of complex cellular layers in the mouse retina. The data are solid, which provides important insights into how ...

The results created 50,000 maps with measurements at more than 29,000 locations across the retina, identifying retinal thinning relating to 294 genes that play an important role in disease. AI ...

State Key Laboratory for Organic Electronics and Information Displays & Jiangsu Key Laboratory for Biosensors, Institute of Advanced Materials (IAM), Jiangsu National Synergistic Innovation Center for ...

The causes range from cataracts and diabetic retinopathy to glaucoma, age-related macular degeneration, and inherited retinal diseases (IRDs). IRDs are genetic conditions that lead to progressive ...

A REDDISH spot can be seen in the centre of the visual field when a white surface is viewed by a normal observer through a dichroic filter transmitting red and blue lights. This phenomenon is ...
