Ten-year outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease.

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.

Polypharmacy-associated potential contraindications of drug prescriptions in patients with primary angle closure disease in a real-world setting.

BACKGROUND: Primary angle closure disease (PACD) is a type of glaucoma in which the intraocular pressure (IOP) is increased because of the blockage of the anterior chamber angle. Medications contraindicated for patients with PACD, such as anticholinergics, cause mydriasis, and can elevate IOP. However, anticholinergics are currently contraindicated only for primary angle closure glaucoma (PACG) in Japanese package inserts. In this study, we investigated the prescription status of medications contraindicated for PACD, such as anticholinergics, in patients with PACD scheduled for eye surgeries. METHODS: Forty-three Japanese patients diagnosed with PACD at Kobe City Eye Hospital, Japan, and scheduled hospitalization for eye surgeries between December 2017 and July 2018, were included. Data, including sex, age, diagnosis, IOP, anterior chamber depth, and patients' regular medications prior to hospitalization, were collected for each patient from the electronic medical records. RESULTS: The number of patients with chronic primary angle closure (CPAC) and acute primary angle closure (APAC) was 35 (81.4%) and 8 (18.6%), respectively. Among all the 43 patients with PACD, 8 (18.6%) received 15 medications that are potentially contraindicated for PACD by non-ophthalmologist. According to medication categories, benzodiazepine hypnotics were the most commonly prescribed. Among the 8 patients with APAC, 2 (25.0%) had routinely received medications contraindicated for PACD. The median number of all kinds of prescriptions on the day of hospitalization was significantly higher for patients who received medications contraindicated for PACD than for those who did not receive them (p = 0.010). CONCLUSIONS: About 20% of patients with PACD received medications potentially contraindicated for PACD, such as anticholinergics. Attention should be paid to patients prescribed multiple drugs for adverse events, such as increase in intraocular pressure.

Comparison of pretreatment measurements of anterior segment parameters in eyes with acute and chronic primary angle closure.

PURPOSE: To compare pretreatment anterior segment parameters between eyes with acute primary angle closure (APAC) and chronic primary angle closure (CPAC), and to identify the characteristics of eyes with APAC. STUDY DESIGN: Retrospective. METHODS: We measured pretreatment anterior chamber depth (ACD), iris convexity (IC), and pupil diameter in eyes with APAC and CPAC using anterior segment optical coherence tomography. The risk of APAC associated with anterior segment parameters was investigated using multiple logistic regression. Eyes with APAC were discriminated from eyes with CPAC using the receiver-operating characteristic (ROC) curve and area under the curve (AUC). The best cutoff for these variables was determined. RESULTS: Thirty-four eyes with APAC and 60 eyes with CPAC were included. The mean intraocular pressure was 52.3 ± 12.6 mmHg in APAC and 15.5 ± 3.5 mmHg in CPAC (P < .001). Eyes with APAC had a shallower ACD (1.407 ± 0.301 mm vs. 1.960 ± 0.205 mm, P < .001) and less IC (0.233 ± 0.087 mm vs. 0.294 ± 0.068 mm, P < .001) than eyes with CPAC. In multivariate analysis, significant variables associated with APAC were ACD (P < .001) and IC (P = .001). The AUC for ACD was 0.931 and for IC, 0.742. The best cutoff for ACD was 1.699 mm (sensitivity 0.824, specificity 0.917) and for IC, 0.282 mm (sensitivity 0.853, specificity 0.533). CONCLUSIONS: Eyes with APAC had a shallower ACD and less IC. Eyes with an ACD < 1.7 mm may be at risk for APAC.
