The new research has showed that the people suffering from a rare eye disease known as ‘Lazy eye’ can be treated. According to data, 1% people around the world suffer from this eye disease.

This illness can affect one or both eyes. It is more common in girls. The researchers have found a connection between this disease and a gene in nervous system. Researchers feel that treatment for ‘Lazy eye’ can evolved based on the new discovery.
 
 The researchers at the University of Aberdeen said that eyes with strabismus The gene – CHN1 when mutated results in production of a gene byproduct known as the hyperactive a2 chimerin. This byproduct leads to eye disorder.

Dr Maria Psatha, University of Aberdeen explained that in normal eye movements, 3 cranial nerves control 6 eye muscles, which control the movement of each eye horizontally, up and down, or at an angle. In DRS, miswiring between the muscles and the nerves can cause some eye muscles to contract when they should not and other eye muscles not to contract when they should. This typically occurs around the sixth week of pregnancy when the cranial nerves and eye muscles develop. During this time, the mutations of the gene of CHN1 have now been shown to explain the pathophysiology of the DRS disorder.

The research found the family history of people suffering from Duane’s Retraction Syndrome (DRS). These people have shown seven mutations in the gene CHN1. These mutations are blamed for the irregular development in the cranial nerve III that is required for the normal eye development during birth.

The researchers assured that this new discovery can help in evolving treatment for ‘Lazy eye’. This treatment will help many people live a normal life who presently suffer from this unique disorder.
