11^th Global Ophthalmology Meeting

Scrutiny of Visual Sensory System

Despite advances in electroencephalogram imaging and other techniques, examination of the afferent visual sensory system is still the core of the neuro-ophthalmologic examination. A thorough refraction is an essential part of all clinical neuro ophthalmologic examinations. Conflict visual fields should be part of every afferent system examination. The relationship between the physical properties of light and perceptual and behavioural responses is known as visual psychophysics, which serves as the foundation for the clinical assessment of visual function. The resolution  of patient’s optical field improves worsens, or remains stable over time is the most difficult aspect of visual field interpretation. Many attempts have been made to investigate visual field function using evoked potentials to visual stimuli.
