Hope for the ongoing treatment for glaucoma which is the second leading cause of blindness worldwide has come following this years Annual meeting of the Association for Research in Vision and Ophthalmology ( ARVO ) which has taken place in Florida.What researchers have been looking at is counterbalancing the pressure that occurs within the eye which is the cause of vision loss with the condition, or the effect of translaminar pressure modification on a rat optic nerve head.Where there is elevated pressure on the optic nerve it tends to bend backwards away from the eye and towards the brain. The optic nerve connects the brain and the eye.
By increasing the pressure in the fluid that surrounded the rats brains they discovered that their brains were responding to light better than rats who had lower pressure. This may well explain why some people who have normal eye pressure sometimes develop glaucoma and why patients with introcular pressure never develop it.
