Anterior capsule phimosis and capsular block syndrome in a patient with Steinert myotonic dystrophy: A case report

Abstract

A 55-year-old man with myotonic dystrophy underwent phacoemulsification with IOL implantation in the right eye. 3 months after surgery, the patient showed a decreased visual acuity and an intraocular pressure (IOP) of 30 mmHg. Slit lamp examination showed a dense fibrosis of the anterior capsule with capsulorexis' shrinkage. Gonioscopy showed a closed angle. After a YAG laser iridotomy no decrease in the IOP was detected; following surgical peeling of the anterior capsule, the slit lamp showed a distended capsular bag. A YAG laser posterior capsulotomy was performed, without decrease in the IOP. Myotonic patients need to be closely followed up after cataract surgery, because in case of CBS development a prompt posterior capsulotomy could avoid more severe complications. © 2009 Rosa et al; licensee BioMed Central Ltd.
