Abstract
A method for destroying retinal pigment epithelial cells in an eye in order to prevent the occurrence of proliferative vitreoretinopathy. A solution containing a basement membrane binding agent conjugated to a cytotoxic agent is introduced into the vitreous chamber. The solution is maintained in the vitreous chamber for a period of time sufficient to permit the basement membrane binding agent to bind to basement membranes lining the vitreous chamber. The solution is then removed from the vitreous chamber, whereby a portion of the basement membrane binding agent remains bonded to basement membranes within the vitreous chamber, thereby exposing retinal pigment epithelial cells disposed on the basement membrane to the cytotoxic agent.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
