Scan identifies cause of inherited blindness

Scan identifies cause of inherited blindness

A team of researchers has identified a new transcription factor scan which identifies the genetic cause of retinitis pigmentosa, an inherited eye disorder which causes blindness.

The multinational collaboration between Regensburg"s Institute of Human Genetics in St Louis, other partners and Genomatix indentified a transcriptional network in photoreceptors and therefore a novel retinal disease gene.

Leading investigator professor Thomas Langmann said the project has allowed the experts to pinpoint "several thousand" target genes for the retinal transcription factor Crx.

"Our technology could helped to gain new insights into this relevant disease mechanism, Better understanding is the first step towards better diagnosis and opens perspectives for a potential therapy, but this is still a long way to go," he added.

Meanwhile, global ophthalmic device company OptiMedica has revealed that results from a clinical study of its Catalys Precision Laser System show that it helped surgeons to achieve a "significant improvement" in precision during several critical steps of cataract surgery.
