Eye 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 کاملThe 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 کاملDepth Estimation using Stereo Fish-Eye Lenses
This paper presents the estimation of depth in an indoor, structured environment based on a stereo setup consisting of two fish-eye lenses, with parallel optical axes, mounted on a robot platform. The use of fish-eye lenses provides for a large field of view to estimate better the depth of features very close to the lens. To extract significant information from the fish-eye lens images, we firs...
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...
متن کاملRadiation Doses in Patient Eye Lenses during Interventional Neuroradiology Procedures.
BACKGROUND AND PURPOSE Eye lenses are among the most sensitive organs to x-ray radiation and may be considered at risk during neurointerventional radiology procedures. The threshold dose to produce eye lens opacities has been recently reduced to 500 mGy by the International Commission on Radiologic Protection. In this article, the authors investigated the radiation doses delivered to patients' ...
