BACKGROUND The objective of recent animal experimental studies is to substitute destroyed or degenerated retina and to improve visual function by transplanting retinal components. Mature or immature retinal components were transplanted into the subretinal space of different animal species. METHODS Embryonic and non-embryonic retina components of different(More)
Different forms of age-related macular degeneration (AMD) can lead to massive visual impairment up to blindness. Therefore, AMD has a high impact on patients' daily life and causes restrictions of their psychological well-being, autonomy and mobility. These restrictions influence their quality of life. It is difficult to define the term "quality of life".(More)
Noonan syndrome (NS) is an autosomal dominant disorder characterized by short stature, congenital heart defects and distinctive facies. The disorder is genetically heterogeneous with approximately 50% of patients having PTPN11 mutations. Prenatally, the diagnosis of NS has been suspected following certain ultrasound findings, such as cystic hygroma,(More)

In this paper the author reports on 6 patients who developed occlusion of a retinal artery following trauma or surgery. Three of these occlusions occurred in the central retinal artery after operations in the orbital area. Two of the operations were ear-nose-throat procedures with subsequent infection, causing compression of the optic nerve and a decrease(More)
Central retinal artery occlusion is caused by embolism or changes in blood rheology and viscosity. In the past, different concepts of treatment were introduced. Main princip is to improve microcirculation by increasing the pressure of perfusion, the diameter of retinal vessels or decreasing blood viscosity. Success of therapy depends on the age of artery(More)
