Scrutiny of Visual Sensory System

Despite advancements in techniques such as electroencephalogram imaging, the examination of the afferent visual sensory system remains fundamental in neuro-ophthalmologic assessments. A comprehensive refraction is integral to all clinical neuro-ophthalmologic examinations. Evaluation of conflicting visual fields should be incorporated into every assessment of the afferent system. Visual psychophysics, which explores the relationship between the physical properties of light and perceptual and behavioral responses, serves as the cornerstone for the clinical evaluation of visual function. Interpreting changes in a patient's optical field resolution over time presents a significant challenge in visual field assessment. Various attempts have been made to explore visual field function using evoked potentials in response to visual stimuli.
