Late capsular block syndrome associated with Propionibacterium acnes.

Late capsular block syndrome (CBS) is a postoperative complication of cataract surgery. It occurs in cases in which there is a 360° adhesion between the continuous curvilinear capsulorrhexis and the anterior surface of the optic of a posterior chamber (PC) intraocular lens (IOL). This adhesion creates the potential for the formation of a sequestered space between the IOL and the posterior lens capsule. In late CBS, a turbid or milky fluid may form within this space, causing posterior distention of the capsular bag. We describe 3 cases of delayed CBS in which the milky fluid was aspirated from the capsular bag and submitted for bacterial culture. Propionibacterium acnes was identified in 2 of these cases.
