The lensing properties of the Plummer model with a central point mass and external shear are derived, including the image multiplicities, critical curves and caustics. This provides a simple model for a flattened galaxy with a central supermassive black hole. For the Plummer model with black hole, the maximum number of images is 4, provided the black hole mass is less than an upper bound which ...

THE results of the experimental investigation carried out in the laboratory of the Netherlands Ophthalmic Hospital in Utrecht to test my first clinical findings on the favourable action of " Corvasymton "t in a chemical burn of the eye have already been recorded (Fischer, Hodgson, and Wagenaar, 1950). In view of the favourable result 1 decided to use this drug once again when a patient with a c...

PURPOSE To correlate a biomicroscopic evaluation, an in vivo confocal microscopy examination, and impression cytologic findings of the corneal center and sclerocorneal limbus after cultured limbal stem cell transplantation and to test the effectiveness of in vivo confocal microscopy as a diagnostic procedure in ocular surface cell therapy reconstructive surgery. METHODS Six eyes of six patien...

Chemical burn injuries are a result of exposure to acid, alkali, or organic compounds. In this retrospective study, a total of 21 patients suffering occupational chemical burns, came to the emergency room at the University General Hospital of Alexandroupolis, from 2008 to 2010; 76.2% were workers, 19% were farmers, and 4.8% were desk officers. The majority of burns were due to exposure to acid ...

In Germany, chemical eye burns are a common and recurring cause of long-term vision disorders and even blindness. Severe eye burns, however, have become less common thanks to sophisticated safety systems and high levels of safety standards in industrial workplaces. In contrast, extremely hazardous substances capable of causing severe eye damage are readily available on the private consumer mark...

HYDROXY-PHENYLBUTAZONE (Tanderil) having proved in many cases an efficacious and less toxic substitute for phenylbutazone (Butazolidin) (Hart and Burley, 1959; Mason and Cramer, 1959), and having been noted by a rheumatologist (O'Reilly, 1958) to have a beneficial effect on iritis associated with rheumatic conditions, Messrs. Geigy have made a quantity available to me for the treatment of ocula...
