Scanning laser ophthalmoscopy ( SLO) is a method of examination of the eye. It uses the technique of confocal laser scanning microscopy for diagnostic imaging of the retina or cornea of the human eye. As a method used to image the retina with a high degree of spatial sensitivity, it is helpful in the diagnosis of glaucoma, macular degeneration ...
The praxinoscope allowed a much clearer view of the moving image compared to the zoetrope, since the zoetrope's images were actually mostly obscured by the spaces in between its slits. Reynaud mentioned the possibility of projecting the images in his 1877 patent, but did not complete his praxinoscope projection device until 1880.
Humphrey field analyser ( HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. [1] The results of the analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease ...
