As a potent collagenase activator,ocriplasmin is a recombinant truncated form of serine protease that retains the protease activity of plasmin.Pre-clinical animal experiments,clinical trials and recent clinical studies all indicated a promising outcome of intravitreal injection of ocriplasmin to treat vitreomacular interface diseases,including vitreomacular adhesion (VMA),vitreomacular traction (VMT) and full-thickness macular hole.Ocriplasmin was approved by the Food and Drug Administration of USA in the management of symptomatic VMA,and by the European Medicines Agency in treating VMT-associated macular hole with less than or equal 400 pm.Further randomized controlled clinical trials are needed for further comprehensive observation and evaluation on its efficiency,safety and other noteworthy issues.
