In this issue we are presenting problems associated with various types of diseases of the eye. Due to the very diverse nature of the topics, I think every reader will find a topic which will be interesting and useful in their everyday medical practice.

The opening paper covers a topic of clinical applications of microperimetry techniques, which is a kind of visual field test that provides the study of retinal sensitivity and the imposition of tests performed on the color fundus image. That technique made the test accurate in identification of defects in the visual field and also allows to monitor disease progression. The authors own clinical experience suggests that microperymetry is extremely useful in the diagnosis and monitoring of central and peripheral retinal lesion of vascular, inflammatory, infectious or degenerative origin.

Following papers are constituted by review articles. The opening paper „Glaucoma and Alzheimer’s Disease – Common Pathomechanisms and Therapeutic Measures”. Glaucoma and Alzheimer’s disease are diseases, which apparently does not have much in common. However, it turns out that they have more of a connection than you would expect. It has been shown, that glaucoma is significantly more common in the patients with Alzheimer’s disease, and, that the mechanisms leading to the cell death in the optic nerve are very similar to the ones observed in neurodegeneration of the brain. This article introduces and systematizes the available knowledge on the subject.
