Patients with a bleb will often experience what sensations following surgery?

After surgery, patients with a bleb, which is an area of elevated tissue that can arise following procedures like trabeculectomy for glaucoma treatment, often report sensations that feel like a foreign body or dryness in the eye. This sensation can be attributed to several factors.

The presence of a bleb alters the normal surface of the eye, which may disrupt the tear film and lead to increased evaporation or irregularity in moisture distribution. As a result, patients may feel that there is something in their eye or that their eye is dry and uncomfortable, contributing to the foreign body sensation.

The condition of a bleb can also lead to fluctuating pressures in the eye, impacting the comfort and sensitivity of the ocular surface. This is often coupled with healing processes post-surgery that may lead to inflammation or irritation of the conjunctiva and surrounding tissues, exacerbating sensations of dryness or foreign body presence.

Overall, this sensation is a common postoperative experience linked specifically to the anatomical and physiological changes associated with the formation of a bleb.
