An ophthalmoscope adapted with a small, central fixation target that projects a shadow onto the retina to assess monocular fixation in amblyopia. The position of the shadow relative to the fovea indicates the type of fixation. Visuoscopy allows direct observation of the retinal fixation point, requiring patients to voluntarily fixate the target. It assumes the foveal reflex accurately demarcates the foveal center.
