PURPOSE: To investigate the long-term outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease (PACD). STUDY DESIGN: Retrospective case series. METHODS: We reviewed the medical records of 87 eyes of 87 patients with PACD who underwent uncomplicated cataract surgery alone at the Kobe City Medical Center General Hospital. Only patients with a minimum follow-up of 10 years were included. The patients were divided into PACD spectrum categories: primary angle-closure glaucoma (PACG), primary-angle closure (PAC), and primary angle-closure suspect (PACS). The treatment outcomes were compared among the 3 groups. Intraocular pressure (IOP), number of glaucoma eye drops, requirement of additional glaucoma treatment, visual field progression, and progression to glaucoma during the follow-up period were evaluated. RESULTS: Among the 87 patients, 39 had PACG; 26, PAC; and 22, PACS. Ten years after surgery, the IOP had significantly decreased from baseline in all 3 groups. The rate of requirement of additional glaucoma treatment during the follow-up period was significantly higher in the PACG group than in the other groups. Almost half of the patients with PACG required additional glaucoma treatment; of those patients, six (15.4%) underwent glaucoma surgery. Three patients (11.5%) with PAC required additional glaucoma medication. Visual field progression was observed in 28.1% of the patients with PACG. In 1 patient with PAC, the condition progressed to PACG, but there was no such progression in any of the patients with PACS. CONCLUSIONS: We confirmed that cataract surgery had a long-term (> 10 years) effect on IOP reduction in eyes with PACD. Early intervention with cataract surgery may be preferable for glaucoma management in patients with PACD.
