RESUMEN
PURPOSE: To evaluate surgical outcomes of the four common procedures utilized for primary angle-closure glaucoma (PACG). METHODS: A retrospective study of survival rate in surgical management of PACG was conducted in a referral eye center. One hundred and ninety-nine eyes from 173 PACG patients were collected for chart review. The procedures used were phacoemulsification (PE), combined PE with goniosynechialysis (PE-GSL), combined PE with trabeculectomy (PE-Trab), and trabeculectomy alone. Failure was defined as postoperative IOP >21 mmHg in patients who needed second surgical intervention or those who had IOP <5 mmHg with loss of light perception. Cumulative survival rates, risk of surgical failure, and complications were analyzed. RESULTS: PE, PE-GSL, PE-Trab, and trabeculectomy were performed in 84 eyes (42.2%), 76 eyes (38.2%), 21 eyes (10.6%), and 18 eyes (9%), respectively. Cumulative survival rates at 60 months were 13%, 55%, 42% and 43%, respectively. Cox regression analysis indicated that each mmHg IOP increased, the risk of surgical failure decreased by 13% (adjusted hazard ratio (HR) 0.87; 95%CI: 0.84-0.93, p<0.001). CONCLUSION: Real-world surgical outcomes of PACG showed that PE alone had a low survival rate of 13% in 60-month follow-up whereas PE-GSL achieved the highest rate of 55%. PE-GSL should be initially considered for management of PACG, since it can restore and sustain the physiologic aqueous pathway and preserve the conjunctiva for future filtering surgery if needed.
RESUMEN
PURPOSE: This study aimed to observe the prevalence and associated factors of neurovascular contact hemifacial spasm (HFS). DESIGN: This was a cross-sectional analytical study. METHODS: Medical records of patients with HFS in a neuro-ophthalmology clinic in Thailand between June 2008 and June 2012 were reviewed. A positive magnetic resonance imaging finding was defined as an adjacent variant vessel that directly compressed or placed pressure on the affected facial nerve. Prevalence and associated factors were analyzed. RESULTS: A total of 60 participants were enrolled, composed of 12 male patients and 48 female patients with a median age of 54 years [interquartile range (IQR), 44.0-64.75] and a disease duration ranging from 4 months to 16 years (median, 2 years; IQR, 1.0-6.0). The prevalence of neurovascular contact HFS was 41.7%. Neurovascular contact HFS was more prevalent among women, with an overall ratio of 3.33. In age group analysis, the prevalence was higher among older patients. In univariate analysis, right-sided symptoms and diabetes mellitus were statistically significant in their association with neurovascular contact HFS (P = 0.040 and P = 0.029, respectively). Right-sided symptoms were significant in a multiple logistic regression analysis (P = 0.038), with an odds ratio of 3.30 [95% confidence interval (CI), 1.07-10.15]. Diabetes mellitus was not statistically significant (P = 0.051), with an odds ratio of 9.99 (95% CI 0.99-96.34). CONCLUSIONS: The prevalence of neurovascular contact in patients with HFS was 41.7%. Right-sided symptoms were significantly associated with this condition.
