Risk factors for undergoing surgery in patients with newly diagnosed open-angle glaucoma.

ABSTRACT: Despite the clinical importance of glaucoma surgery, studies on its prevalence and risk factors are limited. We analyzed a database comprising approximately 1,000,000 Korean residents to investigate the prevalence and risk factors for undergoing glaucoma surgery within 5 years of diagnosis with open-angle glaucoma. Of the 4,303 patients evaluated, 226 (5.3%) underwent glaucoma surgery. Factors associated with the likelihood of glaucoma surgery included the use of two or more eye drops (odds ratio [OR], 30.30; 95% confidence interval [CI], 10.95-83.84), intake of oral carbonic anhydrase inhibitor (OR, 1.79; 95% CI, 1.23-2.61), age > 55 years (55-65 years: OR, 1.71; 95% CI, 1.06-2.76; > 65 years: OR 1.72; 95% CI, 1.10-2.70), female sex (OR, 1.46; 95% CI, 1.10-1.94), middle- and high-income (OR, 2.36; 95% CI, 1.30-4.28, OR, 1.86; 95% CI, 1.03-3.35, respectively), and metropolitan residence (OR, 1.61; 95% CI, 1.14-2.26). Our nomogram for predicting the likelihood of glaucoma surgery showed an acceptable result. In conclusion, older age, female sex, and the intensity of intraocular pressure lowering treatment increased the likelihood of undergoing glaucoma surgery. Our findings indicated that a lower socioeconomic status may forestall receiving this necessary surgery, which requires further attention.

Project description:ImportanceRecent studies indicate that alcohol consumption is linked to increased intraocular pressure and higher prevalence of open-angle glaucoma (OAG). However, there is insufficient evidence to establish any correlation between alcohol abstinence and improved outcomes in patients with OAG.ObjectiveTo evaluate the association between alcohol consumption status (and its changes) and risk of incident severe visual impairment (VI) or blindness in patients with newly diagnosed OAG.Design, setting, and participantsThis retrospective, nationwide, population-based cohort study used the Korean National Health Insurance Service's claims and health examination database to enroll patients who were newly diagnosed with OAG between January 1, 2010, and December 31, 2011, and had been alcohol drinkers before their OAG diagnosis. The cohort was followed up until December 2020. The data were analyzed from February to December 2022.ExposuresThe patients were categorized into 2 groups based on their post-OAG diagnosis alcohol consumption status: sustainers and abstainers. The risks of severe VI or blindness were compared using weighted Cox proportional hazards regression models along with inverse probability of treatment weighting.Main outcomes and measuresIncident severe VI or blindness.ResultsAmong 13 643 patients with newly diagnosed OAG (mean [SD] age, 53.7 [11.9] years; 12 066 men [88.4%]) who were drinkers, 2866 (21.0%) quit drinking after the diagnosis. During 91 366 person-years of follow-up, patients abstaining from alcohol after their OAG diagnosis had a lower risk of severe VI or blindness than did those who had sustained drinking (adjusted hazard ratio [AHR] after inverse probability of treatment weighting, 0.63; 95% CI, 0.45-0.87). Among the sustained drinkers, both mild consumption (<105 g/wk; AHR, 1.52; 95% CI, 1.01-2.28) and moderate to heavy consumption (≥105 g/wk; AHR, 1.78; 95% CI, 1.11-2.86) after OAG diagnosis were associated with higher risk of severe VI or blindness relative to abstainers. Frequent drinking (≥4 d/wk) also was associated with a higher risk of severe VI or blindness (AHR, 2.56; 95% CI, 1.52-4.33) compared with abstinence.Conclusions and relevanceIn this cohort study of patients with OAG who were drinkers, abstaining from alcohol after an OAG diagnosis was associated with lower risk of severe VI or blindness. These findings suggest that lifestyle interventions, such as alcohol abstinence, could be essential for patients with newly diagnosed OAG.

Project description:PurposeTo determine the extent of geographic variation in the proportion of patients with newly diagnosed open-angle glaucoma (OAG) undergoing visual field (VF) testing, fundus photography (FP), and other ocular imaging (OOI) among patients residing in different US communities.DesignRetrospective, longitudinal cohort study.ParticipantsAll enrollees with newly diagnosed OAG enrolled in a managed care network between 2001 and 2014.MethodsWe identified all persons in the plan with incident OAG residing in 201 communities across the United States. All communities contributed ≥20 enrollees. The proportion of enrollees undergoing ≥1 VF test, FP, OOI, and no testing of any type in the 2 years after first OAG diagnosis was determined for each community, and comparisons were made to assess the extent of variation in use of diagnostic testing among patients residing in the different communities.Main outcome measuresReceipt of VF testing, FP, OOI, or none of these tests in the 2 years after initial OAG diagnosis.ResultsOf the 56675 enrollees with newly diagnosed OAG, the mean proportion of patients undergoing VF testing within 2 years of initial diagnosis was 74%±7%, ranging from as low as 51% in Rochester, Minnesota, to as high as 95% in Lancaster, Pennsylvania. The mean proportion undergoing OOI was 63%±10% and varied from 34% in Palm Springs/Rancho Mira, California, to 85% in Charleston, South Carolina. The mean proportion receiving FP was 26%±10% and ranged from as low as 3% in Fresno, California, to as high as 57% in Harlingen, Texas. The proportion undergoing no glaucoma testing ranged from 0% in Binghamton, New York, to as high as 35% in 2 other communities.ConclusionsIn many US communities, a high proportion of patients are undergoing testing according to established practice guidelines. However, in several communities, less than 60% of patients with newly diagnosed OAG are undergoing VF testing in the 2 years after initial OAG diagnosis, and in a few communities >1 in 4 patients have no record of glaucoma diagnostic testing of any type. Additional research is needed to understand factors driving this variation in practice patterns and its impact on patient outcomes.

Project description:PurposeTo identify the incidence rate of motor vehicle collisions (MVCs) in patients with no ocular pathology other than primary open-angle glaucoma (POAG) and determine the putative risk factors for MVCs in this group of patients.MethodsWe designed a prospective cohort study across three centers utilizing a consecutive sampling method to identify all patients with POAG between the ages of 40 and 80 years old. Patients with glaucoma were consecutively screened for eligibility. All study participants answered a questionnaire about motor vehicle collisions at baseline, and answered the questionnaire again every 12 months (± 1 month) after baseline for three years. A binocular integrated visual field was calculated for each patient by merging a patient's monocular Humphrey Field Analyzer (HFA) visual fields (VFs), using the 'best sensitivity' method. Patients with incident MVCs were defined as the "MVC+" group and patients without incident MVCs were defined as the "MVC-" group. Adjusted odds ratios for the incidence of MVCs were estimated with a logistic regression model.ResultsOne hundred and ninety-one Japanese POAG patients were analyzed in this study. The age of the participants was 63.7 ± 10.2 [mean ± standard deviation]. A total of 28 participants experienced a MVC during the follow up period of three years (4.9% per year). Ten patients (5.2%) experienced a MVC in the first year, 13 patients (6.8%) in the second year, and 11 patients (5.8%) in the third year (some patients experienced multiple MVCs over different years). Best corrected visual acuity in the worst eye was significantly worse in the MVC+ group (0.03 ± 0.01, mean ± standard deviation, LogMar) compared with the MVC- group (0.01 ± 0.003, p = 0.01), and was the only variable identified as a significant predictor of future MVCs in the multiple logistic regression model [odds ratio: 1.2, 95% confidence interval (CI): 1.1 to 1.4].ConclusionDeterioration in visual acuity in the worst eye is a risk factor for future MVCs in patients with POAG.
