Purpose:
We evaluated the 3-year clinical outcomes of simultaneous Ahmed valve implantation and vitrectomy in patients with neovascular glaucoma.
Methods:
We retrospectively reviewed 38 eyes that underwent combined Ahmed valve implantation and vitrectomy. Best-corrected visual acuity, intraocular pressure (IOP), and the number of IOP-lowering medications were assessed preoperatively and up to 36 months postoperatively. Patients were categorized into two groups (anterior chamber and vitreous cavity) based on the site of Ahmed valve tube insertion. Clinical outcomes were compared between the two groups. Surgical success was defined as maintaining IOP between 6 and 21 mmHg, with or without topical IOP-lowering medications. Surgical failure was defined as IOP outside this range despite IOP-lowering therapy, loss of vision to no light perception, or the need for valve replacement or additional Ahmed valve implantation.
Results:
The overall surgical success rate was 68.4%; rates were 58.8% in the anterior chamber group and 76.2% in the vitreous cavity group. The mean durations of target IOP maintenance were 24.91 ± 3.45 months in the anterior chamber group and 29.00 ± 2.89 months in the vitreous cavity group, with no significant difference between groups (p > 0.05). Changes in visual acuity before and after surgery did not significantly differ between groups. However, at 36 months postoperatively, the vitreous cavity group required significantly more IOP-lowering medications (p = 0.044). The most common complication was encapsulation removal (39.5%), followed by tube obstruction (10.5%).
Conclusions
Surgical success rates and the duration of target IOP maintenance did not significantly differ between the anterior chamber and vitreous cavity groups. However, patients in the vitreous cavity group required more IOP-lowering medications postoperatively. These findings suggest that the tube insertion site should be considered when planning surgery for neovascular glaucoma.

Purpose:
The number of patients presenting with vaccination-related cardiovascular symptoms after receiving mRNA vaccines (mRNA-VRCS) is increasing. We investigated the incidence of vaccine-related adverse events (VAEs), including myocarditis and pericarditis, in patients with mRNA-VRCS after receiving BNT162b2-Pfizer-BioNTech and mRNA-1273-Moderna vaccines.
Materials and Methods:
We retrospectively collected data on patients presenting with mRNA-VRCS who visited the outpatient clinic of two tertiary medical centers. Clinical characteristics, laboratory findings, echocardiographic findings, and electrocardiographic findings were evaluated. VAE was defined as myocarditis or pericarditis in patients after mRNA vaccination. Clinical outcomes during short-term follow-up, including emergency room (ER) visit, hospitalization, or death, were also assessed among the patients.
Results:
A total of 952 patients presenting with mRNA-VRCS were included in this study, with 89.7% receiving Pfizer-BioNTech and 10.3% receiving Moderna vaccines. The mean duration from vaccination to symptom was 5.6±7.5 days. VAEs, including acute myocarditis and acute pericarditis, were confirmed in 11 (1.2%) and 10 (1.1%) patients, respectively. The VAE group showed higher rates of dyspnea, echocardiography changes, and ST-T segment changes. During the short-term follow-up period of 3 months, the VAE group showed a higher hospitalization rate compared to the control group; there was no significant difference in ER visit (p=0.320) or mortality rates (p>0.999).
Conclusion
Amongst the patients who experienced mRNA-VRCS, the total incidence of VAEs, including acute myocarditis and pericarditis, was 2.2%. Patients with VAEs showed higher rates of dyspnea, echocardiographic changes, and ST-T segment changes compared to those without VAEs. With or without the cardiovascular events, the prognosis in patients with mRNA-VRCS was favorable.

Purpose:
To evaluate the two-year longitudinal changes in subfoveal choroidal thickness (CT) following sulodexide treatment in patients with diabetic retinopathy.
Methods:
Thirty-eight eyes from patients with diabetic retinopathy, followed for a minimum of two years after sulodexide administration, were included. Subfoveal CT, measured using optical coherence tomography, was analyzed prospectively. Variables including age, sex, duration of diabetes mellitus, HbA1c, blood pressure, sulodexide treatment duration, refractive error, axial length, central macular thickness (CMT), visual acuity, laser photocoagulation, and intravitreal anti-vascular endothelial growth factor injections were evaluated for potential effects on CT. CMT, subfoveal CT, and choroidal vascularity index were compared at baseline and at 6, 12, and 24 months after sulodexide.
Results:
Of the 38 eyes, 10 belonged to males and 28 to females. The mean data were as follows: age, 67.18 ± 8.87 years; duration of diabetes, 18.11 ± 7.57 years; HbA1c, 8.76 ± 1.60 mmol/L; systolic blood pressure, 134.69 ± 14.68 mmHg; diastolic blood pressure, 73.72 ± 11.90 mmHg; duration of sulodexide, 25.79 ± 3.17 months; refractive error, 0.22 ± 2.19 diopters (D); and axial length, 23.32 ± 0.89 mm. During the observation period, 15 eyes underwent laser photocoagulation and 17 eyes received intravitreal anti-vascular endothelial growth factor injections. The mean subfoveal CT was 216.00 ± 64.23 μm before sulodexide administration and increased to 223.87 ± 62.18 μm, 225.53 ± 62.02 μm, and 225.76 ± 63.62 μm at 6, 12, and 24 months, respectively (p = 0.0377, p = 0.0159, p = 0.0135). The CMT was 318.14 ± 102.28 μm initially and changed to 313.08 ± 77.47 μm, 314.97 ± 88.32 μm, and 320.03 ± 97.36 μm at the aforementioned intervals, with no significant variation (p = 0.904, p = 0.736, p = 0.892).
Conclusions
Sulodexide administration led to a significant rise in subfoveal CT over a 2-year follow-up. This change in CT was not mirrored in the CMT.

Objective:
Coronavirus disease 2019 (COVID-19) has notably altered the emergency department isolation protocol, imposing stricter requirements on probable infectious disease patients that enter the department. This has caused adverse effects, such as an increased rate of leave without being seen (LWBS). This study describes the effect of fever/respiratory symptoms as the main cause of isolation regarding LWBS after the COVID-19 pandemic.
Methods:
We retrospectively analyzed emergency department visits before (March to July 2019) and after (March to July 2020) the COVID-19 pandemic. Patients were grouped based on existing fever or respiratory symptoms, with the LWBS rate as the primary outcome. Logistic regression analysis was used to identify the risk factors of LWBS. Logistic regression was performed using interaction terminology (fever/respiratory symptom patient [FRP] × post–COVID-19) to determine the interaction between patients with FRPs and the COVID-19 pandemic period.
Results:
A total of 60,290 patients were included (34,492 in the pre–COVID-19, and 25,298 in the post–COVID-19 group). The proportion of FRPs decreased significantly after the pandemic (P < 0.001), while the LWBS rate in FRPs significantly increased from 2.8% to 19.2% (P < 0.001). Both FRPs (odds ratio, 1.76; 95% confidence interval, 1.59–1.84 (P < 0.001) and the COVID-19 period (odds ratio, 2.29; 95% confidence interval, 2.15–2.44; P < 0.001) were significantly associated with increased LWBS. Additionally, there was a significant interaction between the incidence of LWBS in FRPs and the COVID-19 pandemic period (P < 0.001).
Conclusion
The LWBS rate has increased in FRPs after the COVID-19 pandemic; additionally, the effect observed was disproportionate compared with that of nonfever/respiratory symptom patients.

OBJECTIVES:
The purpose of this study was to identify and compare the difference and related factors with general characteristic and health behaviors, a experience of diagnosis and treatment of chronic diseases between rural and urban among elderly in Korea.
METHODS:
We used the data of Community Health Survey 2017 which were collected by the Korean Center for Disease Control and Prevention. The study population comprised 67,835 elderly peopled aged 65 years or older who participated in the survey. The chi-square test, univariate and multivariate logistic regression analysis were used to analyze data.
RESULTS:
We identified many significant difference of health behaviors, an experience of diagnosis and treatment with chronic diseases between rural and urban. Compared to urban elderly, the odds ratios (ORs) (95% confidence interval) of rural elderly were 1.136 (1.092–1.183) for diagnosis of diabetes, 1.278 (1.278–1.386) for diagnosis of dyslipidemia, 0.940 (0.904–0.977) for diagnosis of arthritis, 0.785(0.736–0.837) for treatment of arthritis, 1.159 (1.116–1.203) for diagnosis of cataracts, and 1.285(1.200–1.375) for treatment of cataracts. In the experience of diagnosis and treatment of chronic diseases, various variables were derived as contributing factors for each disease. Especially, there were statistically significant difference in the experience of diabetes diagnosis, arthritis diagnosis, cataract diagnosis and dyslipidemia except for hypertension diagnosis (p<0.01) between urban and rural elderly. There were statistically significant differences in the experience of treatment for arthritis and cataract (p<0.01), but there was no significant difference in the experience of treatment for hypertension, diabetes, dyslipidemia between urban and rural elderly.
CONCLUSION
Therefore, it would be necessary to implement a strategic health management project for diseases that showed significant experience of chronic diseases with diagnosis and treatment, reflecting the related factors of the elderly chronic diseases among the urban and rural areas.
