In medicine a bleb is a large blister (usually approximately hemispherical) filled with serous fluid. Blebs can form in a number of tissues due to different pathologies including frostbitten tissues and as a cause of spontaneous pneumothorax. In the lungs a bleb is a collection of air within the layers of the visceral pleura. In ophthalmology blebs may be formed intentionally in the treatment of glaucoma.
