A clot in the retinal vein can lead to severe and irreversible loss of vision. In a report in the American Journal of Pathology investigators utilize a newly developed model of central retinal vein occlusion (CRVO) in mice that mimics many of the clinical features of CRVO in humans to study the pathologic effects of retinal occlusion and demonstrate the retinoprotective effects of the peptide adrenomedullin (ADM) and its receptor activity-modifying protein RAMP2.

Although currently laser surgery is a very popular tool for various vision disorders correction, it is still difficult to ensure proper control over the accuracy, efficiency and safety of such procedures. Therefore, Russian scientists have proposed a new method to describe tissue changes after such operations. This method was described in a series of publications in the Journal of Biophotonics, the Journal of Biomedical Optics and Laser Physics Letters.
