The Eye and Photographic Lenses.
It appeared incomplete but formed a considerable segment of a circle. The above description applies chiefly to -the left iris. The departure from the normal. was less marked in the right eye. The writer believes this to be a case of congenital miosis of varying degree in the two eyes, and due probably, having regard to the findings of Holth and Berner, to developmental faults in the dilator mus...
متن کاملEye irrigating lenses.
Treatment of chemical bums requires rapid dilution of the chemical, decreasing eye exposure to the toxic material. Prolonged exposure to the chemicals can lead to decreased visual acuity, and even loss of the eye (Pfister, 1983). ffighly caustic compounds can be found in industry and agriculture, as well as at home (Duane, 1981). Alkalies are usually more damaging than acids, due to rapid penet...
متن کاملOptimization of Head CT Protocol to Reduce the Absorbed Dose in Eye Lenses and Thyroid: A Phantom Study
Introduction: Utilization of computed tomography (CT) scans is increasing annually. This study aimed to reduce the absorbed dose of sensitive organs in the head (eye lenses and thyroid) and to assess changes in resultant images quality in head scans when the radiation dose is decreased. Material and Methods: An anthropomorphic phantom was examined with head protocols in both helical and sectio...
متن کاملTHE PHOTOGRAPHIC EYE BY A. HYATT MAYOR Curator of Prints
Though magnifiers, drawing machines, and cameras have been used in making works of art for a long time, their connection with technique and style has received only passing mention. Yet devices that affect the way we see are bound to affect style in art, since style both reflects and conditions ways of seeing. Everybody's seeing is constantly changing. The hat 1/ that startled at Easter looks no...
متن کاملNa,K-ATPase in simulated eye bank and cryoextracted rabbit lenses, and human eye bank lenses and cataracts.
In the rabbit, cryoextraction of the lens and subsequent storage in Tyrode's solution did not alter the Na,K-ATPase activity from that determined in immediately excised rabbit lenses. Similarly, the procedures employed with the rabbit eye to simulate collection and storage of normal human eyes (eye banking) had no effect upon the Na,K-ATPase activity of the lens. These results permitted the inv...
