Completed morning program. Looked up Akshat at Gurgaon. He is having fever for the last few days. Venita will stay with him for 4 days. In chamber from 3.30 to 5 pm.
Retired to sleep at 11.30 pm.
News of the day : "London: Scientists have discovered 24 new genes that cause refractive errors and myopia (short-sightedness).
Myopia is a major cause of blindness and visual impairment worldwide, and currently there is no cure.
These findings could lead to finding better treatments or ways of preventing the condition in the future.
During visual development in childhood and adolescence the eye grows in length, but in myopes it grows too long, and light entering the eye is then focused in front of the retina rather than on it. This results in a blurred image. This refractive error can be corrected with glasses, contact lenses or surgery.
However, the eye remains longer, the retina is thinner, and this may lead to retinal detachment, glaucoma or macular degeneration, especially with higher degrees of myopia. Myopia is highly heritable, although up to now, little was known about the genetic background.
To find the genes responsible, researchers from Europe, Asia, Australia and the United States collaborated as the Consortium for Refraction and Myopia (CREAM

he new genes include those, which function in brain and eye tissue signalling, the structure of the eye, and eye development. The genes lead to a high risk of myopia and carriers of the high-risk genes had a tenfold increased risk.
It was already known that environmental factors, such as reading, lack of outdoor exposure, and a higher level of education could increase the risk of myopia. The condition is more common in people living in urban areas.
An unfavourable combination of genetic predisposition and environmental factors appears to be particularly risky for development of myopia. How these environmental factors affect the newly identified genes and cause myopia remains intriguing, and will be further investigated by the consortium.
Professor Chris Hammond from the Department of Twin Research and Genetic Epidemiology at King`s College London, and lead author of the paper, said: "We already knew that myopia - or short-sightedness - tends to run in families, but until now we knew little about the genetic causes. This study reveals for the first time a group of new genes that are associated with myopia and that carriers of some of these genes have a 10-fold increased risk of developing the condition."
These findings have been published in the journal Nature Genetics." The Z News on line dt 12.02.2013
