Statistical Eye Model for Normal Eyes

Statistical eye model for normal eyes.

PURPOSE To create a binocular statistical eye model based on previously measured ocular biometric data. METHODS Thirty-nine parameters were determined for a group of 127 healthy subjects (37 male, 90 female; 96.8% Caucasian) with an average age of 39.9 ± 12.2 years and spherical equivalent refraction of -0.98 ± 1.77 D. These parameters described the biometry of both eyes and the subjects' age...

Eye ancestry: Old genes for new eyes

The vast differences between vertebrate and arthropod eyes suggest that the recently discovered homologous master control genes for eye development had another function before eyes evolved in the early Cambrian.

Effect of tropicamide and homatropine eye drops on a-scan parameters of the phakic normal eyes.

OBJECTIVES A prospective study to evaluate the changes in A-Scan axial parameters of phakic normal eyes before and after instillation of 1% topical Tropicamide and 2% Homatropine eye drops. METHODS Anterior chamber depth, lens thickness, vitreous chamber length, and ocular axial length were measured in 76 eyes before and after cycloplegia induced by 1% topical Tropicamide, and in 28 eyes with...

A New Model for Text Coherence Evaluation using Statistical Characteristics

Tracking Eyes and Monitoring Eye Gaze

In this paper, we present a non-intrusive eye tracker which can detect and track a user's eyes in real time as soon as the face appears in the view of the camera without special lighting or any marks on the user's face. We also discuss the problem of gaze monitoring. We employ neural networks to estimate a user's eye gaze using the images of user's both eyes as input to the neural networks. We ...
