“…According to a meta-analysis, the estimated PACG prevalence in Chinese women was higher compared with men (1.9% vs 1.1%; adjusted OR: 1.75, 95% CI, 1.20–2.56; P = 0.004) [ 65 ]. In Korea, women had a 2.56 folds higher incidence rate of acute angle closure glaucoma than men [ 66 ]. Though a study reported female (56.6%) was more at odds of developing glaucomatocyclitic crisisris, most studies have shown a male predilection [ 67 ].…”

Background Ambient air pollution is related to the onset and progression of ocular disease. However, the effect of air pollutants on the acute glaucoma remains unclear. Objective To investigate the effect of air pollutants on the incidence of acute glaucoma (acute angle closure glaucoma and glaucomatocyclitic crisis) among adults. Methods We conducted a time-stratified case-crossover study based on the data of glaucoma outpatients from January, 2015 to Dec, 2021 in Shanghai, China. A conditional logistic regression model combined with a polynomial distributed lag model was applied for the statistical analysis. Each case serves as its own referent by comparing exposures on the day of the outpatient visit to the exposures on the other 3–4 control days on the same week, month and year. To fully capture the delayed effect of air pollution, we used a maximum lag of 7 days in main model. Results A total of 14,385 acute glaucoma outpatients were included in this study. We found exposure to PM2.5, PM10, nitrogen dioxide (NO2) and carbon monoxide (CO) significantly increased the odds of outpatient visit for acute glaucoma. Wherein the odds of acute glaucoma related to PM2.5 and NO2 were higher and more sustained, with OR of 1.07 (95%CI: 1.03–1.11) and 1.12 (95% CI: 1.08–1.17) for an IQR increase over lag 0–3 days, than PM10 and CO over lag 0–1 days (OR:1.03; 95% CI: 1.01–1.05; OR: 1.04; 95% CI: 1.01–1.07). Conclusions This case-crossover study provided first-hand evidence that air pollutants, especially PM2.5 and NO2, significantly increased risk of acute glaucoma.

“… 14 Nationwide studies in Korea and Scotland reported females comprising 72.6% and 64% of acute angle closure presentations. 15 , 16 A smaller anterior chamber is a risk factor for APAC, and the higher prevalence of this ocular characteristic in females likely contributes to the higher incidence. 17 , 18 Furthermore, female life expectancy is higher than that of males in the United States and worldwide, and the shift towards a female-predominant population in older age groups may be contributory.…”

Purpose Acute primary angle closure (APAC) is an ophthalmologic emergency. Nationwide data on the epidemiology and clinical characteristics of APAC are lacking despite the associated visual morbidity. Patients and Methods A retrospective cross-sectional study using the Nationwide Emergency Department Sample (NEDS). The NEDS was queried by ICD-9/10 code for cases of APAC presenting to the United States emergency departments over a ten-year period from 2008 to 2017. All identified cases were included to produce nationally representative estimates. Linear regression and seasonality tests were used to identify trends. Reported outcomes include the incidence, demographics, seasonality, and economic impact of APAC regionally and nationwide. Results A total of 23,203 APAC-related ED visits were identified. The mean (SD) and median ages were 58.8 (16.2) and 60 years, respectively. Females (59.4%, p < 0.01), those in the lowest income quartile (6983, 30.1%, p < 0.01), and those in the seventh decade of life (5599, 24.1%) presented more frequently with APAC. The incidence of ED presentations within each age group rose with age and increased significantly over the study period (p < 0.01). The Northeast region had the highest average incidence (0.93 per 100,000 population). Significant seasonal variation was seen regionally and nationally (p < 0.01), with the highest average incidence in December and lowest in April. Median inflation adjusted charge per ED visit was $2496.10, and the total inflation adjusted charges equaled $101.5 million. Conclusion The incidence of APAC-related ED visits continues to rise in the United States. High-risk groups include women, individuals of low socioeconomic status, and those between ages 50 and 70. Significant seasonal and regional trends were observed in ED presentations of APAC.

“…This incidence is higher than that in the general population in Asia, which typically ranges from 6 to 12 per 100,000. (29,30) The increased occurrence can be attributed to shallower ACD and a higher LAF in RAM eyes. This raises concerns regarding access to the angle by gonioscopy technique or earlier laser iridotomy in high-risk patients, as indicated by data from the IOL Master.…”

Background/Objective: Relative anterior microphthalmos (RAM) is a rare ocular condition characterized by disproportionately small anterior segments but normal axial length (corneal diameter < 11 mm and axial length > 20 mm). This study aimed to determine the prevalence of RAM and its association with glaucoma utilizing IOL Master 700 data (Carl Zeiss Meditec, Jena, Germany). Subject/Methods: A retrospective analysis was conducted of the biometric parameters of 6,407 eyes, and 115 cases of RAM were identified. The incidence of glaucoma was assessed, together with the outcomes of cataract surgery in cases of RAM with glaucoma. Results RAM prevalence was 1.8%. RAM patients had a higher incidence of glaucoma (26.1%), notably of the angle-closure subtype. Cataract surgery significantly reduced intraocular pressure in cases of RAM with glaucoma; however, RAM patients experienced a higher rate of surgical complications. Conclusion RAM poses clinical challenges due to its association with glaucoma and increased surgical risks. This study emphasizes the importance of advanced diagnostic tools such as the IOL Master in tailoring interventions to optimize patient outcomes.
