[Congenital color vision disorders in persons with mental disorders].

Colour vision was studied in 3000 mental patients (2000 males and 1000 females) with different diseases by means of polychromatic tables and a spectral anomaloscope AH-59. It was established that the frequency of genetically determined pathology of colour vision in patients (9,3% in males and 08,% in females) is similar to the pathology found in the general population and does not depend upon the clinical diagnosis. At the same time there was a large amount of patients with acquired disorders to colour perception (30% of the general pathology of colour vision).

Bilateral symmetry of vision disorders in typical retinitis pigmentosa.

Bilateral symmetry of disorders of vision is examined in 60 typical patients with retinitis pigmentosa. We observed a very high degree of interocular congruence in the patterns of both kinetic visual field defects and threshold profiles and in abnormalities of foveal colour discrimination and visual acuity. Abnormalities of foveal colour vision are highly correlated with the extent of visual field loss.

Cerebral disorders of vision in systemic lupus erythematosus.

Sensory neuroophthalmic abnormalities due to cerebral lupus erythematosus, with involvement of visual pathways posterior to the optic chiasm, occurred in 12 patients with systemic lupus erhthematosus. Five underwent detailed evaluation because of an hallucination, 4 for visual loss, and 3 for both. Hallucinations were either unformed (for example, bright lights, straight lines) or highly formed (for example, faces), in which case they were invariably recognized by the patient as inappropriate. In no instance did they occur in association with delirium, confusion, or use of hallucinogenic drugs. Patients with loss of vision had scotomas, homonymous field defects, and cortical blindness. These features indicate disease in the posterior cerebral artery circulation, a localization often supported by ancillary neurologic findings, for example, vocal cord paralysis, diminished gag reflex. Thus, various visual dysfunctions may occur in systemic lupus erythematosus due to cerebral vasculitis. At times they may be the most prominent and disabling feature of the disorder.
