After suspending the intravitreal injection, the eye is evaluated to rule out complications such as a perforation of the sclera. Postoperatively, the eye is monitored for signs of inflammation and signs of infection in order to make any necessary treatment or medication. Some patients do not respond well to postoperative topical steroids; however, some patients seem to respond well and are off the topical steroids within a few days. The postoperative follow-up may extend out to a couple of weeks depending on the surgical eye drop regimen and the need for additional eye drops for postoperative inflammation. The laser spot or edges will turn whitish up to a week after treatment. The corneal edema will clear in about two to seven days. In rare cases, the corneal edema can clear over a longer period of time ,. Many people with a history of trachoma have had a RLE, and most do not seem to have a problem with trichiasis, although re-trachomatis is possible .
The only ocular effect that I can find are very small amounts of extra-ocular hypotony (passive intraocular pressure (IOP) less than 6 mmHg) , a prolapse of the iris into the anterior chamber (iris bombe) , and phthisis bulbi, when the eye eventually fails and becomes nonfunctional .
Xenon has become the gas of choice for maintenance of general anesthesia. Xenon has properties which are different from nitrous oxide. The normal threshold for general anesthesia is 1.5 parts per million in oxygen. Xenon at mean gas mixture level is 0.7 parts per million, and the minimum alveolar concentration is 65% at sea level. These properties have made xenon a popular choice for maintenance of general anesthesia. However, xenon has a very narrow range of safety above the normal alveolar concentration. Xenon is water insoluble and poorly absorbed by the GI tract. When xenon is inhaled, it dissipates relatively rapidly into the blood stream and is ultimately excreted by the kidneys. d2c66b5586
