The presence of pseudocystic lesions always associated with severe optic nerve fiber loss is reported. The reason why pseudocystic lesions develop within the retina is not well understood. They might constitute the translation of degeneration of Muller cells in severe optic nerve fiber loss. Recognizing these pseudocysts is crucial because they may be confused with cystoid macular edema. Their prognostic value and role in the therapeutic process need to be further evaluated with prospective studies and molecular experiments in vivo.

The in-vivo accuracy of three-dimensional intravascular ultrasound (3D IVUS) is significantly high regardless of the type of the coronary arteries or their particular geometrical and morphological characteristics. This finding further supports the applicability of the method for either diagnostic or investigational purposes.

Operating on a unilateral congenital corneal opacity is a challenging decision and should be taken after explaining the need for long-term follow-up to the parents. Useful vision can be achieved and maintained after strict amblyopia therapy. A multidisciplinary ophthalmologic follow-up is necessary.

Problem: Bird migration (eye): Georeferencing procedure with clues, rules, functionalities, and restrictions, for avian navigation and nest nidification. Literature Knowledge: Computer vision (sensor): Robot self-referencing with the Perspective-n- Point pose estimation technique. Aim: Hypothesis introduction and proving (“The birds also follow the same georeferencing procedure like robots in avian navigation and nest nidification”). Methodology: (a) Reference data, images, and photography acquisition and 4-means layering (eBird dataset, Flickr imagery, CORINE land covering, and Volunteered Geographic Information); (b) Image processing; and (c) GIS spatial overlay analysis. Results: Statistical spatial analysis using data of the GIS overlays (the 4 layers). Correlation matrix (Avian navigation and nest nidification in low-density urban areas as these are affected by spatial linear geometries and land cover types). Conclusion: A statistically satisfactory approach to the introduced hypothesis. Potential Applications: Human spatial cognition and movement behavior; Children’s motor control and coordination.

En face OCT is a noninvasive and reproducible technique that helps to better assess and follow up retinal and choroidal processes in Type 2 macular telangiectasia.
