Subjektivität und Objektivität optischer Wahrnehmungen*

Journal/Book: Erfahrungsheilkunde. 2001; 50/7: 400-405.

Abstract: Aim: The relationship between subjectivity and objectivity of optical perceptions in ophthalmology is characterized by the fact of incommensurabilty, i.e. by the discrepancy in principle between the objective physical external space and the subjective psychophysiologic space sense. Three kinds of localization are presented.Method and material: Criticism of the Cartesian division of subject and object, i.e. criticism of the hypothetical passivity of the patients, who were watched and the reproductivity of all measurements. By the example of visual anomalies in patients with macula degeneration and metamorphopsias, the fundamental non-measurability of perception disorders is shown. For this reason, the situation of the patient is only partially comprehensible for the physician. Asymmetries, disproportions and pseudomovements lead to three-dimensional disorientation.Results: The measurability of optical perceptions is limited to the Euclidean space. In the hyperbolical and spherical geometry, the measurement is aggravated, whereas 'it 'is impossible in the fractal pathological space sense.Conclusion: Among the above mentioned conditions, subjectivity gains greater importance in diagnosis and therapy than objectivity. The numeric results of ophthalmologic examinations are strictly speaking rather estimations. This is due to the fact, that perceptions are complex, irregular dynamic processes (synesthesia and synergy of sensory organs), and are primarily subjected to the rules of quantum physics and to the uncertainity principle.
