The image shows an en face OCT visualization of macular photoreceptor loss in choroideremia. Recently, en face OCT image processing methods together with machine and deep learning techniques have facilitated the segmentation of photoreceptor loss in diseases where low outer retinal layer contrast is used to yield to numerous segmentation errors and low-quality visualization of damaged areas (e.g. in inherited retinal diseases (1,2) and diabetic retinopathy (3)). Segmentation result by a fully convolutional network is also shown.

Having edited several technical publications over the last decade, I crossed paths with quite a few of Texere's current team members, and I only ever heard them sing the company's praises. When an opportunity arose to join Texere, I jumped at the chance! With a background in literature, I love the company's ethos of producing genuinely engaging content, and the fact that it is so well received by our readers makes it even more rewarding.
