Anatomical comparisons of the horizontal visible iris diameter (HVID) and the average keratometry (Kav) measurements were made between Asians and Caucasians and also between males and females. It was found that the HVID was significantly different as a function of both culture and gender. Also found … The mean widths for the left maxillary central incisor were 6.1 mm, 7.8 mm, and 8.4 mm. The mean value for right and left iris diameter for 100 participants was 11.9 mm. Minimal differences were observed in values between right and left sides (Table 1). The mean maxillary central incisor widths and HVID were higher in men than women (Table 2). Measurement of the horizontal visible iris diameter does not include the limbal width, which means that the horizontal visible iris diameter is an underestimate of the true corneo‐limbal diameter.

However, the few that do mention the methodology typically refer to the method of measuring the horizontal visible iris diameter (HVID) which, as the name implies, refers to the horizontal diameter of the iris within the clear corneal zone. DIAMETER The horizontal visible iris diameter (HVID) is the main factor to consider in determining the lens diameter.

They are considered as indicative of a suffering iris sector. A similar significance is attributed to tangential vessels andfork vessels which, once they have reached the area adjacent to the outer iris border, run perpendicularly to the border touching or delimiting iris areas which are considered as suffering.

Existing iris recognition systems are heavily dependent on specific conditions, such as the distance of image acquisition and the stop-and-stare environment, which require significant user cooperation. In environments where user cooperation is not guaranteed, prevailing segmentation schemes of the iris region are confronted with many problems, such as heavy occlusion of eyelashes, invalid off Iris; Iris in humans, is the colored (typically blue or brown) area, with the pupil (the circular black spot) in its center, and surrounded by the white sclera.Overlying cornea is completely transparent so is not visible, except the high-gloss luster it gives the eye. Also pictured are the red blood vessels within the sclera. These structures are easily visible on any person's eyes.
