Bergen Ophthalmogenetic Research Group

Hereditary eye disorders are a major cause of visual impairment in children and adolescents. Genetic factors are also important for the development of eye disorders in adult life. Identification of the genetic cause of eye disorders is important for precise diagnosis and is essential for rational management and development of novel therapies.

Main content

The Bergen Ophthalmogenetic Research Group is a collaborative effort between investigators at the University of Bergen and Haukeland University Hospital.

The aim of the group is to identify genetic causes of eye disorders and to study the consequences of the genetic defects at a cellular and molecular level both in patients and model organisms.
