Imaging cone photoreceptor inner segments in the living human eye.
Advances in high resolution imaging technology provide unique opportunities for clinicians and researchers to study the living retina. Adaptive optics (AO) are used to correct monochromatic aberrations of the eye and, when used in conjunction with a scanning light ophthalmoscope (SLO), enable visualization of the rod and cone photoreceptors. While much research has been directed toward quantify...
متن کاملMeasurement of the photoreceptor pointing in the living chick eye
The chick eye is used in the study of ocular growth and emmetropization; however optical aberrations in the lens and cornea limit the ability to visualize fine retinal structure in living eyes. These aberrations can be corrected using adaptive optics (AO) allowing for cellular level imaging in vivo. Here, this capability is extended to measure the angular tuning properties of individual photore...
متن کاملExcessive Myosin activity in mbs mutants causes photoreceptor movement out of the Drosophila eye disc epithelium.
Neuronal cells must extend a motile growth cone while maintaining the cell body in its original position. In migrating cells, myosin contraction provides the driving force that pulls the rear of the cell toward the leading edge. We have characterized the function of myosin light chain phosphatase, which down-regulates myosin activity, in Drosophila photoreceptor neurons. Mutations in the gene e...
متن کاملThe reflectance of single cones in the living human eye.
PURPOSE Individual cones were imaged in the living human eye with the Rochester adaptive optics ophthalmoscope. In all eyes, there were large differences in the reflectance of different cones, even when all the photopigment was bleached. To help understand what produces this spatial variation, the investigators explored whether it is a static or a dynamic property of the cone mosaic. METHODS ...
متن کاملImages of cone photoreceptors in the living human eye
Though the photoreceptor mosaic has been imaged through the intact optics of the eyes of several species, it has not been clear whether individual photoreceptors can be resolved in the living human eye. We have constructed a high-resolution fundus camera and have resolved cones with a spacing as small as 3.5 microns in single images of the fundus. The high contrast of these images implies that ...
