Scotoma Peripheral

Peripheral scotoma is a disorder of central and peripheral vision, in which in one half of the visual field vision is significantly reduced or completely absent against the background of preserved clear consciousness and consistency of visual functions. The central scotoma appears as a flat or ascending fissure, located in the region of the bitemporal point of gaze fixation and shifting with eye movement. A peripheral scotoma is a negative spherical or elliptical zone of decreased sensitivity, the central part of which is occupied by the optic disc and the surrounding retina. Disturbance of the central zone is often associated with bilateral visual hallucinations, pathological catoptrokinesis, contralateral hemianopsis, and corneal process.
