In a new study from the L V Prasad Eye Institute (LVPEI) and Biological Psychology and Neuropsychology (BPN) at the University of Hamburg, researchers were able to differentiate between sight recovered individuals with a history of dense, total bilateral congenital vs. bilateral developmental cataracts using a neural marker of visual processing. The findings could aid clinical prognosis and rehabilitation, clinical research on treatment outcomes, and epidemiological studies on the genetic origins of cataracts. The results were published in EClinicalMedicine, a journal published by The Lancet.
Childhood cataract is one of the major causes of avoidable blindness worldwide. Dense cataracts prevent pattern vision, allowing only diffuse light to reach the retina through the clouded eye lenses. Cataracts in children can have congenital or developmental origins, and typically, these distinct origins have different expected outcomes after sight recovery.
