PURPOSE Non-penetrating deep sclerectomy has been performed in France since the early nineties and appears to be an interesting alternative to Cairn's trabeculectomy. The technical characteristics, the ability to use antimitotic procedures and postoperative YAG laser goniotomy contribute to make deep sclerectomy an attractive surgical method. We evaluated(More)
The locomotor response of juvenileGinglymostoma cirratum, the nurse shark, to six covert, discrete sources of an attractant chemical stimulus (fresh shrimp extract) was monitored in a tank (5×5×0.5 m) by means of a square matrix of 1936 photocells embedded in the floor and an on line computer. The experiments were done in flowing (1.17 cm/s) and stagnant(More)
PURPOSE To evaluate the effects of contact transscleral cyclophotocoagulation with neodymium YAG laser for refractory glaucoma. METHOD This was a retrospective study with 36 patients (37 eyes) who were treated at the Rouen Hospital from February 1996 to February 2001. Patients had various types of glaucoma: glaucoma in pseudophakia (12), primary(More)
The functional results of the treatment of primary open angle glaucoma (POAG) were analysed. A retrospective study was undertaken on 437 eyes from 282 patients (137 women, 145 men) followed in Saint Joseph's Hospital (Paris). The mean follow-up was 9.7 years (4-22 years). 265 eyes received only medical treatment, 83 eyes argon laser trabeculoplasty (ALT)(More)
The cluster of galaxies A2256 was observed by the PCA and HEXTE experiments aboard the RXTE satellite during the period July 2001 January 2002, for a total of ∼343 ks and ∼88 ks, respectively. Most of the emission is thermal, but the data analysis yields evidence for two components in the spectrum. Based on statistical likelihood alone, the secondary(More)
