A method to simulate and model metamorphopsia by means of a deformable Amsler grid is proposed. The interactively deformable grid is based on cubic B-splines to obtain a locally controlled deformation. By simulating metamorphopsia on normal sight volunteers, acquisition of a correction percentage is possible as a result of analyzing the magnitude of the(More)
This work presents the development of an augmented reality magnification system implemented in a head-mounted display for surgical applications. The system provides a magnified view with a novel control based on tracked sight orientation. The system was evaluated by measuring the completion time of a suturing task performed by surgeons. The magnifying(More)
This work presents the development of an augmented reality magnification system, termed virtual loupe, implemented in a head-mounted display for surgical applications. The system provides a magnified view with a novel control based on tracked sight orientation. The system was evaluated by measuring the completion time of a suturing task performed by(More)
The activity of beta-N-acetylglucosaminidase (NAG), beta-galactosidase, alpha-L-fucosidase, beta-glucuronidase, beta-glucosidase and alpha-mannosidase was determined in the urine of rats at progressive ages from newborn to old animals. The age-dependence of urinary creatinine, protein and pH values was also studied. Enzyme activity, related to urinary(More)
