Drug treatment for cataracts moves a step closer
Cataract is a clouding of the eye lens that develops over time and affects the quality of vision. It is caused by a disorganization of the proteins in the lens that leads to clumps of protein forming, which scatter light and severely reduce transmission to the retina. Cataracts cause vision loss and blindness for millions of people worldwide.

In laboratory trials, treatment with the oxysterol compound VP1-001 showed an improvement in refractive index profiles—a key optical parameter that is needed to maintain high focusing capacity—in 61% of lenses. This means that the protein organization of the lens is being restored, resulting in the lens being better able to focus. This was supported by a reduction in lens opacity in 46% of cases.

Improvements occurred in some types of cataract but not in all, indicating that this may be a treatment for specific cataracts. This suggests distinctions may need to be made between cataract types when developing anti-cataract medications. It is a significant step forward towards treating this extremely common condition with drugs rather than surgery.
