RT Journal Article SR Electronic T1 Delayed microhyphaema with intraocular lenses: a retrospective study of eight patients. JF British Journal of Ophthalmology JO Br J Ophthalmol FD BMJ Publishing Group Ltd. SP 106 OP 110 DO 10.1136/bjo.73.2.106 VO 73 IS 2 A1 L Butler A1 M J Roper-Hall YR 1989 UL http://bjo.bmj.com/content/73/2/106.abstract AB Eight patients with delayed microhyphaema were identified from a computer data base of 1209 patients who had had cataract extraction with Binkhorst 4-loop intraocular lens insertion. Five cases were recurrent. The cases were examined to try and identify an underlying cause. No single cause was identified, but trauma, hypertension, and oral anticoagulants were found to be associated. Some episodes were asymptomatic. The wide variety of surgical technique and style of lens with which this complication has been reported implies multiple causative factors. The source of the bleeding and its management are discussed.
