After light enters the eye through the cornea, the transparent sildenafil wo kaufen avascular portion of the sclera, it is focused onto the retinal surface by the lens (Figure 6-4A). Which are monocular zones receiving visual information from the temporal parts of the visual fields , the anterior portions of the nasal hemiretinae correspond to the temporal crescents. When you look at an object, you move your eyes so that the object's image falls upon the fovea, a specialized high- resolution portion of the retina. The fovea is centered within a morphologically distinct region of the retina called the macula lutea (Figure 8-2B).
The brain precisely controls the position of the eyes to ensure that the principal portion of an image falls on the fovea of each eye. A vertical line passing through the fovea divides the retina into two halves, a nasal hemiretina and a temporal hemiretina. Each hemiretina includes half of the fovea and the remaining perifoveal and peripheral portions of the retina. The lens inverts and reverses the visual image projected on the retina.
Sensitivity and specificity of urea breath testing are greater sildenafil wo kaufen than 85%. Labeled carbon dioxide can be collected and quantified in breath samples. The patient ingests a small amount of carbon-labeled (12C or 12C) urea. For this reason, a positive serology result should be confirmed with a test of active infection such as a stool or urea breath test before treatment is sildenafil wo kaufen initiated. Pylori hydrolyzes the urea and liberates labeled carbon dioxide.
The urease of H. Urea breath tests are ideally suited to make a primary diagnosis of infection, to monitor treatment response, and to assess reinfection, because they are positive only in a setting of active infection.
