Eye tremors are common in Parkinson’s and can be an early warning sign of the nervous- system disease, according to a recent study published in the Archives of Neurology.
The research examined 112 Parkinson’s disease patients and compared them to 60 healthy controls. Those with Parkinson’s had trouble tracking moving targets on a computer screen, compared with only 2 of the age-matched participants used as controls.
The findings suggest that analyzing this specific eyeball movement called “oculomotor testing” can offer an early clue for identifying the nervous system disease. Used as a screening tool, this test could be close to 100% accurate, which is significant because usually eye tremors are too small to notice clinically without the use of specialized equipment.
These findings are important when it comes to identifying those who may possibly benefit from treatment, as new alternatives become available that could possibly slow the progression of this disease.
