A new method of preventing a blinding condition that is a result of diabetes has been discovered by scientists. This condition tends to block a second blood vessel growth protein. Diabetes related eye conditions occur when the normal vessels of the eye tend to get replaced after certain duration with leaky, abnormal and weak blood vessels which tend to leak fluid or bleed in the eye. This causes damage to the light sensitive retina and can result in blindness.
Laser sealing techniques eye blood vessels are capable of saving central vision. However, this often results in sacrificing night and peripheral vision. Studies show that even though many recently developed drugs can treat these blood vessels by blocking VEGF action. However, these drugs slow down progression, but are not very reliable when it comes to prevention.
A number of experiments in a laboratory environment where human cells and mice were involved showed a second culprit for this condition which is a protein called angiopoietin-like 4. The researchers of this experiment blocked the action of the both the angiopoietin-like 4 and VEGF present in the eye fluid of people that have proliferative diabetic retinopathy. This markedly decreased blood vessel growth of the laboratory grown cells.
According to one of the researchers, the result suggested that although VEGF tends to clearly play a crucial role in the growth of the blood vessel, it is not the only responsible factor.
At present, the team is busy investigating if the angiopoietin-like 4 substance can also play a greater role in other medical eye conditions like macular degenerations. Macular degeneration tends to damage and destroy the central region of the retina.
