A survey study on the physiological variations in the field of vision with constitutional types in Ayurveda

Abstract

Introduction: Ayurveda, the Indian traditional system of medicine, describes a unique concept “Prakriti” (human somatic constitution), categorizing the population into seven subgroups based on phenotypic characters. Prakriti influences the eyes in terms of size, shape, appearance, dryness or roughness, movement, and various specific features of the eye. These relates to the constitutional variations of the Volunteers. No correlation has been explored between Prakriti and field of vision yet. This study was carried out to explore a possible correlation between Prakriti and field of vision. Methods: This cross-sectional study was conducted on 50 volunteers of age between 18 and 30 years. Prakriti and field of vision of the participants were assessed. One-way ANOVA test and Karl Pearson's correlation coefficient tests were used for the analysis. The assessment of mean and standard deviation value of the field of vision as per Prakriti was done. Results: A statistically significant association was found between fields of vision of both eyes with Prakriti. A positive correlation was found between superior, inferior, nasal, temporal side of field of vision of the right eye with superior, inferior, nasal, and temporal side of field of vision of the left eye. A positive correlation was found between the superior side of field of vision of right and left eyes among Shleshma Pittala-Shleshma, and Vatala-Pittalaprakritis. Conclusion: Anatomical and physiological variations of the eyes of different Prakriti volunteers affect the field of vision. Sleshma prakriti volunteers had greater degree of field of vision as compared to other Prakriti.
