[Functional monocular hemianopsia].
Certain patients with reduction or loss of central visual function and/or hemianopic changes of the visual field can be classified as well-informed malingerers, individuals who are easily influenced by suggestion, or neurotics suffering from "conversion hysteria." The main symptom is one of a functional sensory change (loss or reduction of visual field). The task falling to the ophthalmologist is to prove the contrary, using certain subjective and objective tests to prove the incompatibility of the results with the physiological facts. The authors discuss the specificity of these tests in this context and present a number of cases with the characteristic temporal or nasal functional hemianopsia comparing them with patients who have hemianopsias due to real anatomic lesions.
