[A comparative study of the manual and digital measurements of the palpebral fissure].
OBJECTIVE
To compare the measurement of the palpebral fissure done either manually and by computer analysis of image of individuals without lid alterations.


METHODS
One hundred two palpebral fissures from 51 normal subjects have been analyzed. The patients' age ranged from 17 to 84 years, with 25 (49%) males and 26 (51%) females.


RESULTS
There was no statistically significant difference between the measurements done either manually or by computer analysis of images, neither, when we grouped the patients by sex or age. Also we did not observe difference between males and females, and regarding age.


CONCLUSIONS
The results obtained by both methods are comparable and reliable due to the statistical equivalence of the obtained measurements.
