PURPOSE: To report a case of acute glaucoma due to complete ring cyst of the ciliary body. PATIENTS AND METHODS: A 33-year-old woman experienced blurred vision in her left eye. Intraocular pressure of the left eye was elevated accompanied with a very shallow anterior chamber. Anterior segment-optical coherence tomography and ultrasound biomicroscopy detected ring-shaped ciliary masses in the both eyes. Myopic change and contact between the ciliary mass and lens in the left eye suggested the presence of aqueous misdirection resulting in forward displacement of the lens-iris diaphragm. Because elevated intraocular pressure was refractory to conservative management, the left eye underwent clear lens aspiration and implantation of intraocular lens. RESULTS: Although the anterior chamber became deep in the left eye initially after lens extraction in conjunction with core vitrectomy, possible aqueous misdirection recurred. Second vitrectomy in the left eye together with posterior and anterior capsulotomies, to establish humoral communication between the anterior and posterior chambers, deepened the anterior chamber and lowered the intraocular pressure. The anterior chamber in the fellow right eye remained deep a year after the episode. CONCLUSIONS: This is the first reported case of bilateral ring cysts of the ciliary body. The manifestation caused secondary glaucoma, which was resolved by lensectomy and vitrectomy.
