Metamorphopsia associated with central retinal vein occlusion.

ABSTRACT: This prospective study aimed to investigate metamorphopsia in eyes with central retinal vein occlusion (CRVO) and included 28 eyes (28 patients) with unilateral CRVO that had macular edema (ME) in the acute phase. The ME was treated with anti-vascular endothelial growth factor agents. At baseline and at 1 and 6 months after initiation of treatment, quantitative measurements of metamorphopsia were performed using M-CHARTS and the retinal morphologic changes were examined by optical coherence tomography. At baseline, metamorphopsia was detected on M-CHARTS in 14 (50.0%) eyes. The mean M-CHARTS score was 0.37 ± 0.53. At 1 month and 6 months after initiation of treatment, there was substantial resolution of ME and significant recovery of visual acuity. In contrast, metamorphopsia was still detected in 16 eyes at 6 months; the mean M-CHARTS scores were 0.29 ± 0.37 at 1 month and 0.32 ± 0.38 at 6 months, and had not significantly improved from baseline (p = 0.580, and p = 0.604, respectively). Although the M-CHARTS score at 6 months was associated with the baseline M-CHARTS score (p = 0.004), it did not have any associations with morphologic parameters at baseline. However, the M-CHARTS score at 6 months was significantly associated with foveal photoreceptor status, height of serous detachment, and parafoveal thickening at 1 month. Metamorphopsia associated with CRVO could be quantified using M-CHARTS, and often persisted in contrast with the recovery of visual acuity and resolution of ME after treatment with anti-vascular endothelial growth factor agents.

Project description:PurposeTo identify risk factors associated with central retinal vein occlusion (CRVO) among a diverse group of patients throughout the United States.DesignLongitudinal cohort study.ParticipantsAll beneficiaries aged ≥ 55 years who were continuously enrolled in a managed care network for at least 2 years and who had ≥ 2 visits to an eye care provider from 2001 to 2009.MethodsInsurance billing codes were used to identify individuals with a newly diagnosed CRVO. Multivariable Cox regression was performed to determine the factors associated with CRVO development.Main outcome measuresAdjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of being diagnosed with CRVO.ResultsOf the 494 165 enrollees who met the study inclusion criteria, 1302 (0.26%) were diagnosed with CRVO over 5.4 (± 1.8) years. After adjustment for known confounders, blacks had a 58% increased risk of CRVO compared with whites (HR, 1.58; 95% CI, 1.25-1.99), and women had a 25% decreased risk of CRVO compared with men (HR, 0.75; 95% CI, 0.66-0.85). A diagnosis of stroke increased the hazard of CRVO by 44% (HR, 1.44; 95% CI, 1.23-1.68), and hypercoagulable state was associated with a 145% increased CRVO risk (HR, 2.45; 95% CI, 1.40-4.28). Individuals with end-organ damage from hypertension (HTN) or diabetes mellitus (DM) had a 92% (HR, 1.92; 95% CI, 1.52-2.42) and 53% (HR, 1.53; 95% CI, 1.28-1.84) increased risk of CRVO, respectively, relative to those without these conditions.ConclusionsThis study confirms that HTN and vascular diseases are important risk factors for CRVO. We also identify black race as being associated with CRVO, which was not well appreciated previously. Furthermore, we show that compared with patients without DM, individuals with end-organ damage from DM have a heightened risk of CRVO, whereas those with uncomplicated DM are not at increased risk of CRVO. This finding may provide a potential explanation for the conflicting reports in the literature on the association between CRVO and DM. Information from analyses such as this can be used to create a risk calculator to identify possible individuals at greatest risk for CRVO.
