Chung Yee Chung, Kenneth Kai Wang Li
The wide-field montage technique of optical coherence tomography angiography provides good delineation of the improvement in microvascular disturbance associated with branch retinal vein occlusion after treatment with anti-vascular endothelial-derived growth factor injection. It may be further evaluated for the assessment of treatment progress in patients with retinal vein occlusion.

Two illustrative cases of chronic branch retinal vein occlusion are presented with multimodal imaging, including commercially available optical coherence tomography angiography. In these two patients, retinal ischemia and collateral vessels were well imaged without the need to use traditional fluorescein angiography. Optical coherence tomography angiography provides useful information for the diagnosis and management of patients with branch retinal vein occlusion and other retinal vascular diseases.

Prediction of treatment responses from available data is key to optimizing personalized treatment. Retinal diseases are treated over long periods and patients' response patterns differ substantially, ranging from a complete response to a recurrence of the disease and need for re-treatment at different intervals. Linking observable variables in high-dimensional observations to outcome is challenging. In this paper, we present and evaluate two different data-driven machine learning approaches operating in a high-dimensional feature space: sparse logistic regression and Random Forests based extra trees (ET)...

Robert W Flower, Ronn Kling
A clinical method for characterizing the state of micro-vasculature vasomotion is demonstrated, based on observing in capillaries the dynamics of autologously re-injected erythrocytes containing ICG dye. Since a manifestation of vasomotion is transient erythrocyte pausing, vasomotion state within a field of capillaries is characterized by an histogram plot of the number of paused erythrocytes as a function of pause duration during a fixed period of observation, then the ratio of long-pausing to short-pausing erythrocytes was calculated...
