Amblyopia: neural basis and therapeutic approaches.
Abnormalities in visual processing caused by visual deprivation or abnormal binocular interaction may induce amblyopia, which is characterized by reduced visual acuity. Occlusion therapy, the conventional treatment, requires special attention as occlusion of the fellow normal eye may reduce its visual acuity and impair binocular vision. Besides recovering visual acuity, some researchers have re...
متن کاملUnderstanding the neural basis of amblyopia.
Amblyopia is the condition in which reduced visual function exists despite full optical correction and an absence of observable ocular pathology. Investigation of the underlying neurology of this condition began in earnest around 40 years ago with the pioneering studies conducted by Hubel and Wiesel. Their early work on the impact of monocular deprivation and strabismus initiated what is now a ...
متن کاملContrast-coding in amblyopia. I. Differences in the neural basis of human amblyopia.
To shed light on the basis of normal contrast perception in general and its susceptibility during early visual development in particular the contrast-coding deficit of amblyopic eyes was investigated. This was accomplished by using two different but complementary paradigms, one involving equating the contrast sensations between the amblyopic and normal fellow eye and the other involving the ass...
متن کاملNeural mechanisms underlying amblyopia.
The nature of the neural basis of amblyopia is a matter of some debate. Recent neurophysiological data show correlates of amblyopia in the spatial properties of neurons in primary visual cortex. These neuronal deficits are probably the initial manifestation of the visual loss, but there are almost certainly additional deficits at higher levels of the visual pathways.
متن کاملMolecular basis of therapeutic approaches to gastric cancer.
Gastric cancer is the top lethal cancer in Asia. As the majority of cases present with advanced disease, conventional therapies (surgery, chemotherapy, and radiotherapy) have limited efficacy to reduce mortality. Emerging modalities provide promise to combat this malignancy. Target-protein-based cancer therapy has become available in clinical practice. Numerous molecules have been shown potenti...
