BACKGROUND: Bilateral malignant glaucoma induced by a capsular tension ring associated with ring-shaped cysts of the ciliary body post-cataract surgery is rare. Herein, we present a case to highlight the possibility of capsular tension ring-induced malignant glaucoma.
CASE PRESENTATION: A 59-year-old woman underwent phacoemulsification combined with capsular tension ring implantation for cataracts and zonular fibre laxity in both eyes. Upon admission, annular ciliary masses were detected in both eyes using ultrasound biomicroscopy. Two months post-surgery, the patient experienced vision deterioration, high intraocular pressure, and an axial shallowing anterior chamber in the right eye, and responded poorly to traditional anti-glaucoma medication. Ten days later, similar symptoms appeared in the left eye. Ultrasound biomicroscopy detected contact between the ciliary body and the capsular tension ring. Subsequently, malignant glaucoma was diagnosed. Anterior and posterior capsulotomies performed peripheral to intraocular lens optics using neodymium: YAG laser restored communication and alleviated the symptoms. A one-year follow-up revealed stable intraocular pressure and anterior chamber in both eyes.
CONCLUSIONS: This is the first case report of bilateral malignant glaucoma after cataract surgery induced by capsular tension ring, which is associated with bilateral ring-shaped cysts of the ciliary body. Blockage between the ciliary body and capsular tension ring was confirmed using ultrasound biomicroscopy.
