Episodic elevations in intraocular pressure associated with blood in the schlemm canal.

Comment. Althoughhyphema isone of the most common early postoperative complications following trabeculectomy, to our knowledge, intralenticular collection of blood has not been previously reported. Because of the use of an operating microscope and the refinement of surgical techniques, lens injury during trabeculectomy has been infrequently reported. We hypothesized that there had been anterior capsule injury while performing peripheral iridectomy in this case, with seepage of blood into the capsular bag. The development of a fibrous type of posterior capsule opacification in relation to the presence of blood in the capsular bag, as was evident from the exaggerated postoperative capsular bag fibrosis in this case, has been previously noted. This case highlights the possibility of lens injury during trabeculectomy and provides an insight into the problems encountered while performing phacoemulsification when there is intralenticular blood collection.
