Background/aimsSocioeconomic status (SES) is associated with late disease presentation and poorer outcomes. We evaluate the effect of SES on treatment outcomes and report the correlation between SES and baseline characteristics of participants in the Treatment of Advanced Glaucoma Study.MethodsPragmatic multicentre randomised controlled trial. Four hundred and fifty-three patients presenting with advanced open-angle glaucoma in at least one eye (Hodapp-Parrish-Anderson classification). Participants were randomised to either glaucoma drops (medical arm) or trabeculectomy (surgery arm). Clinical characteristics, Quality of life measurement (QoL) and SES defined by the Index of Multiple Deprivation are reported. Subgroup analysis explored treatment effect modifications of SES at 24 months. Correlation between SES and baseline characteristics was tested with the χ2test of association for dichotomous variables and pairwise Pearson’s correlation for continuous variables.ResultsThe mean visual field mean deviation was −17.2 (6.7)dB for the most deprived quintile of participants and −13.0 (5.5) for the least deprived quintile in the index eye. At diagnosis, there was a strong correlation between SES and ethnicity, age, extent of visual field loss and number of visits to opticians prior to diagnosis. At 24 months, there was no evidence that the treatment effect was moderated by SES.ConclusionsIn patients presenting with advanced glaucoma. SES at baseline is correlated with poorer visual function, poorer Visual Function Questionnaire-25 QoL, ethnicity, age and number visits to an optician in the years preceding diagnosis. SES at baseline does not have an effect of the success of treatment at 24 months.Trial registration numberISRCTN56878850.

Incident glaucoma and ocular hypertension after periocular and intravitreal steroid injections: a claims-based analysis

Author: Gupta, Divakar ; Horns, Joshua ; Stagg, Brian C ; Wirostko, Barbara M ; Grewal, Dilraj S ; Liu, Katy C ; Polski, Ashley

Background/aimsThis study aims to determine the incidence and risk of open-angle glaucoma or ocular hypertension (OHT) following ocular steroid injections using healthcare claims data.MethodsWe retrospectively reviewed deidentified insurance claims data from the IBM MarketScan Database to identify 19 156 adult patients with no prior history of glaucoma who received ocular steroid injections between 2011 and 2020. Patient demographics and steroid treatment characteristics were collected. Postinjection glaucoma/OHT development was defined as a new diagnosis of glaucoma/OHT, initiation of glaucoma drops, and/or surgical or laser glaucoma treatment. Cox proportional hazards models were used to determine the risk of glaucoma/OHT development within 5 years after first steroid injection.ResultsOverall, 3932 (20.5%) patients were diagnosed with new glaucoma/OHT, 3345 (17.5%) started glaucoma drops and 435 (2.27%) required a laser or surgical glaucoma procedure within 5 years of first steroid injection. Triamcinolone subconjunctival injections were associated with a lower risk of glaucoma/OHT development than retrobulbar or intravitreal steroid injections (p<0.001, HR 0.68, 95% CI 0.59 to 0.79), whereas the 0.59 mg fluocinolone acetonide intravitreal implant had the highest risk of glaucoma/OHT development (p=0.001, HR 2.01, 95% CI 1.34 to 3.02). The risk of glaucoma/OHT development was also higher for patients receiving multiple steroid injections (p<0.001), with the largest increase in risk occurring after three total steroid injections.ConclusionPatients receiving ocular steroid injections are at risk of developing glaucoma/OHT, even with no prior glaucoma/OHT diagnosis or treatment. Patients should be closely monitored for the development of glaucoma following ocular steroid injections, particularly in the setting of intravitreal and/or repeated steroid administration.

Predictors of long-term intraocular pressure control after lens extraction in primary angle closure glaucoma: results from the EAGLE trial

Background/aimsTo assess baseline ocular parameters in the prediction of long-term intraocular pressure (IOP) control after clear lens extraction (CLE) or laser peripheral iridotomy (LPI) in patients with primary angle closure (PAC) disease using data from the Effectiveness of Early Lens Extraction for the treatment of primary angle-closure glaucoma (EAGLE) tria.MethodsThis study is a secondary analysis of EAGLE data where we define the primary outcome of ‘good responders’ as those with IOP<21 mm Hg without requiring additional surgery and ‘optimal responders’ as those who in addition were medication free, at 36-month follow-up. Primary analysis was conducted using a multivariate logistic regression model to assess how randomised interventions and ocular parameters predict treatment response.ResultsA total of 369 patients (182 in CLE arm and 187 in LPI arm) completed the 36-month follow-up examination. After CLE, 90% met our predefined ‘good response’ criterion compared with 67% in the LPI arm, and 66% met ‘optimal response’ criterion compared with 18% in the LPI arm, with significantly longer drops/surgery-free survival time (p<0.05 for all). Patients randomised to CLE (OR=10.1 (6.1 to 16.8)), Chinese (OR=2.3 (1.3 to 3.9)), and those who had not previously used glaucoma drops (OR=2.8 (1.6 to 4.8)) were more likely to maintain long-term optimal IOP response over 36 months.ConclusionPatients with primary angle closure glaucoma/PAC are 10 times more likely to maintain drop-free good IOP control with initial CLE surgery than LPI. Non-Chinese ethnicity, higher baseline IOP and using glaucoma drops prior to randomisation are predictors of worse long-term IOP response.
