ABSTRACT
AIMS: This study examined the long-term effects of nitrous oxide anaesthesia on serum levels of cobalamin and folate, red cell folate levels and haematological parameters, and neurological status in elderly Omani patients. METHODS: Sixty-nine consecutive patients undergoing ophthalmic surgery were randomly and double-blind assigned to nitrous oxide or propofol anaesthesia. They met the following entry criteria: age 55 years or above, no major organ failure, no clinical signs or symptoms of cobalamin or folate deficiency, mean cell volume (MCV)

We developed a prospective clinical study to determine the effectiveness of a new method of retrobulbar anesthesia and akinesia of the levator and orbicularis muscles. This study involved 50 patients who underwent extracapsular cataract extractions (ECCE) with intraocular lens implant (IOL). We found levator and orbicularis muscle akinesia was achieved in 49 of 50 eyes. One reblock was necessary. We also wish to point out the advantages of this technique as a means of reducing the rare but serious complications associated with retrobulbar anesthesia.

We present the early results in a small series of 12 eyes of 12 patients with uncontrolled glaucoma who underwent trabeculectomy with implantation of a Mendez Glaucoma Seton. All eyes, except one with neovascular glaucoma, had had multiple glaucoma surgery and all, without exception, were on maximal tolerated medical therapy prior to surgery. The follow-up period ranged from one and one fourth to three and three fourths months. The surgical technique was the same in all cases. Our success rate was 33.3% or 40%, if one eye with persistent hypotonia could be counted as a success. This result is inferior to those quoted in the literature with the use of other types of setons, and especially to the results of Dr. Antonio Mendez who used a similar implant.
