Аннотация
RATIONALE: Malignant glaucoma is a refractory glaucoma which often relentlessly worsened despite conventional therapy. Ultrasonographic biomicroscopy always cannot show the ciliary-block of malignant glaucoma. We report a case of capsular tension ring induced ciliary-block and successfully treated by low dose laser cyclophotocoagulation, with 1-year follow-up.
PATIENT CONCERNS: A 75-year-old woman was referred for glaucoma with a history of cataract and lens zonular laxity, and surgery with combined phacoemulsification and capsular tension ring implantation. She subsequently underwent trabeculectomy for uncontrolled intraocular pressure on maximal medical therapy. One day later, the patient presented as shallow anterior chamber of Shaffer grade 1 and an elevated intraocular pressure of 51.0 mmHg in the right eye.
DIAGNOSIS: Ciliary block caused by capsular tension ring and malignant glaucoma was observed.
INTERVENTIONS: Low dose laser cyclophotocoagulation was performed under retrobulbar anesthesia.
OUTCOMES: One day later, the patient's intraocular pressure decreased to 14.3 mmHg on topical atropine 1% and 2 classes of intraocular pressure lowering medications. The patient discontinued topical atropine and intraocular pressure lowering medications 4 months postoperatively and her condition had remained stable for 1 year without any medications. The patient had a satisfactory recovery benefited from the low dose laser cyclophotocoagulation.
LESSONS: Low dose laser cyclophotocoagulation in this challenging case of capsular tension ring-induced malignant glaucoma provided an effective and fast recovery of anterior chamber depth over a 1-year period.
