Another use for Avastin… blebs!
Bevacizumab (Avastin) may have an application as an adjunct to antifibrosis therapy, according to study results published in the October/November issue of the Journal of Glaucoma.
Bevacizumab (Avastin) may have an application as an adjunct to antifibrosis therapy, according to study results published in the October/November issue of the Journal of Glaucoma.
Michael A. Coote, MBBS, FRANZCO of the University of Melbourne, Australia and colleagues administered a subconjunctival injection of bevacizumab to a bleb. The team monitored bleb vascularity and measured any longitudinal changes that occurred in the six months prior to, and for the six months following, the bevacizumab injection.
Three months after one eye underwent trabeculectomy, cataract surgery was required; 10 days postoperatively, increased scarring activity was correlated to bleb vascularity. The researchers found that the single subconjunctival injection of bevacizumab was associated with a significant reduction in bleb vascularity for six weeks and, at six months, with additional continued steroid therapy, the bleb functioned well, had minimal scar tissue and was healthy and diffuse.
Because the bleb responded so well to the bevacizumab injection, the researchers concluded that this treatment may provide an effective adjunct to antifibrosis therapy, although further studies into bevacizumab’s effect on bleb scarring activity are required.

Evaluating the clinical performance of ZEISS AT ELANA and the new ’ELISA’* approach
August 5th 2025In this insightful analysis, Dr. Joong Hun Kim presents real-world clinical outcomes with bilateral implantation of ZEISS AT ELANA 841P. Dr. Kim recommends AT ELANA® 841P as an excellent option for patients undergoing cataract surgery as its fully trifocal optical design translates into a full range of vision. He also introduces the so-called ‘ELISA’ approach for patients requiring astigmatic correction in one eye only, combining AT ELANA 841P and ZEISS AT LISA tri toric 939MP. Early objective and subjective clinical data from this novel approach reveal promising visual outcomes and high patient satisfaction
