New drug delivers sight for sore eyes

A potential improved treatment for two of the leading causes of blindness – age and diabetes-related eye problems – has been demonstrated in research involving a University of Queensland expert.

person looking through medical equipment Professor Di Yu of the UQ Diamantina Institute collaborated with scientists from the Chinese Academy of Sciences and Beijing Chaoyang Hospital to address an issue affecting approximately 450 million people worldwide.

“There is a high prevalence of ocular neovascular disease, with 415 million people at risk of loss of sight through diabetes, and as many as 50 million with age-related macular degeneration,” Professor Yu said.

“With an aging population, the number of cases of age-related macular degeneration is expected to increase as much as five-fold by 2040.

“At the moment, ocular neovascular diseases are treated by a method that suppresses a particular growth factor for vessels, but between 40 and 60 per cent of patients do not respond well.

“Those who do not respond well might exude fluids, have unresolved or new bleeding, thickening or scarring of tissue, or fail to recover functional vision.

“In our study of a novel treatment in animals, volumes of lesions were reduced by 95 per cent.”
