In [[medicine]], '''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 [[frostbite|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]]. In [[geology]], [[mineralogy]], [[petrology]], and related geochemical sciences, '''bleb''' is a noun or descriptive term meaning the inclusion of a [[mineral]] within a larger mineral that is bubble-like. Commonly used for small inclusions, such as ones tens of micrometres in size. An example usage in the literature is a bleb of [[sylvite]] in [[chlorite group|chlorite]]. ==See also== *[[Blue rubber bleb nevus syndrome]] *[[Glaucoma valve]] ==External links== *Medical definition of bleb on [http://www.medterms.com/script/main/art.asp?articlekey=2480 MedicineNet.com] *[http://www.blebs.net/html/Protocol.html Moorfields Bleb Grading System] ==References== *Sunil JS. 2005.
