[Retinal artery and vein occlusions].

Retinal artery and vein occlusions can both lead to significant vision loss. Vein occlusions are much more common, while visual acuity is usually more severely affected in artery occlusions. In addition to ophthalmological treatment, both types of occlusions require a multidisciplinary approach, in which cardiovascular risk management is important.

Association between Contrast Sensitivity and Reading with Macular Pathology.

Significance: Comparison between the role of spatial and temporal contrast sensitivities in the association with reading may provide insight into how visual tasks (such as reading) are related to primary optical or neural (or both) effects. More insight into primary visual factors influencing reading is important for understanding reading problems.

Purpose: The aim of this study was to gain insight into the association between optical and neural components of contrast sensitivity (CS), operationalized as spatial CS (optical and neural) or temporal CS (solely neural), and reading speed in a clinical sample of participants with macular pathologies.
