Washington: Women`s eyes may actually be different from men`s as a new study has revealed that healthy emmetropic women have a bigger pupil diameter than men.From an anatomical point of view, a normal, non-pathological eye is known as an emmetropic eye, and has been studied very little until now in comparison with myopic and hypermetropic eyes.Normal, non-pathological emmetropic eyes are the most common type amongst the population (43.2 percent), with a percentage that swings between 60.6 percent in children from three to eight years and 29 percent in those older than 66.Therefore, a study determines their anatomical pattern so that they serve as a model for comparison with eyes that have refractive defects (myopia, hypermetropia and stigmatism) pathological eyes (such as those that have cataracts).“We know very little about emmetropic eyes even though they should be used for comparisons with myopic and hypermetropic eyes,” said Juan Alberto Sanchis-Gimeno, researcher at the University of Valencia and lead author of the study explains to SINC.The project shows the values by gender for the central corneal thickness, minimum total corneal thickness, white to white distance and pupil diameter in a sample of 379 emmetropic subjects.
