What would cause my bleb to enlarge?
If you are talking about a bleb resulting from glaucoma surgery then this is certainly a possible occurrence. The wall of the bleb can become thinned and stretched over time. This could result in discomfort, foreign body sensation or even loss of vision if the bleb encroaches on the cornea. If the bleb is enlarging but not causing any problems it can be observed. However, if you develop any of the above issues then a bleb revision surgery may be required. It is also important not to rub (or put pressure on) the eye containing a glaucoma bleb.
