Sherwood, Roger A. Hitchings, Jonathan G. Drowston (editors), Glaucoma, Volume 2: Surgical Management, page 236, If the leak allows bulk flow of aqueous, the rest of the bleb can collapse, allowing apposition of the inflamed inner bleb walls, which are likely to adhere. If such adherence is over most or all of the bleb area, bleb failure is probably inevitable.

Use of intraoperative antimetabolites is a risk factor for the development of a bleb leak. The mechanism of a bleb leak is thought to be as follows. Ischemic blebs are stretched and surrounded by heavily scarred tissue, which limits the ability of the aqueous to flow beyond the scarred tissue. The bleb expands locally, producing a tractional hole when the tissue overreaches its maximal stretch.

Figure 4.20 reveals blebs on the surface of a bacterial cell. In many instances, these blebs are released from the cell into the surrounding media.
