seven cases of visual field defects, caused by wartrauma were seen at farabi eye hospital. none were referred by a neurologist. four patients had 20/20 visions with normal fundi. one had 12/20, in both eyes, with normal fundi. two patients presented fundus changes. the visual field defects were seen in all these seven patients. four had homonymous hemianopia, one had bilateral field restriction...

Free electromagnetic fields, satisfying Maxwell's equations with no charges and electric currents, can be described by complex vector fields. In the standard formulation fields sharply dependent on position time, one obtains integrals that are mathematically ill-defined. This happens for massless Pauli--Jordan function, which is used to describe time evolution of appears in Poisson brackets cla...
