Nasopupillary asymmetry.

Arenas E, Muñoz D, Matheus E, Morales D - ScientificWorldJournal (2014)

Bottom Line: To establish the prevalence of nasopupillary asymmetry (difference in nasopupillary distances) in the population and its relation with the interpupillary distance.The values of nasopupillary asymmetry and the interpupillary distance were obtained.A statistical analysis was made and the correlation between these variables was established.

ABSTRACT

Purpose: To establish the prevalence of nasopupillary asymmetry (difference in nasopupillary distances) in the population and its relation with the interpupillary distance.

Methods: A retrospective descriptive study was conducted by reviewing of 1262 medical records. The values of nasopupillary asymmetry and the interpupillary distance were obtained. A statistical analysis was made and the correlation between these variables was established.

Results: Seventy-nine percent of the population presented some degree of nasopupillary asymmetry. The interpupillary distance had a very low correlation with the nasopupillary asymmetry (r = 0.074, P = 0.0).

Conclusion: It is advisable to use the nasopupillary distance of each eye as a standard measurement.

Mentions: The ID and NPD measurement was performed all the time by the same specialist utilizing the Essilor pupillometer calibrated by long distance. The instrument shows the ID and also the two separate nasopupillary distances (right and left eyes) (Figure 1). The NPA was obtained by calculating the difference between the NPD of the right eye (RE) and the NPD of the left eye (LE), for each patient. Data was collected and a statistical analysis for the entire population was performed.
