Perimetric Findings in Pseudotulor Cerebri Using Automated Techniques
Abstract The authors obtained automated static threshold visual fields in 44 eyes of 22 patients with pseudotumor cerebri. Severe defects were found in 9% and moderate defects in 68%. The pooled incidence of three recent studies using manual kinetic techniques also demonstrated 9% severe defects, but only 34% of eyes demonstrated moderate loss. In 20 of 44 eyes, the papilledema was felt to be severe or atrophic. In none of these eyes was a normal field obtained. Visual field defects in pseudotumor cerebri appear to be more common than previously thought.
Summary In the pilot study, a new geomodeling technology is presented for developing 3D heterogonous geomodels for Athabasca McMurray (MCMR) oil sands. The geomodels were used to simulate SAGD thermal recovery. Both conventional SAGD completions and SAGD with ICD completions were tested. The simulation results show that for a heterogeneous Athabasca McMurray oil sand reservoir, the ICD completion technology enhances oil production and reduces steam consumption. As a result, the economics of SAGD recovery from the heterogeneous sands is improved.
