BREAKING COVID-19 News! Chinese Study Discovers That SARS-CoV-2 Increases The Risk For Developing Acute Angle-Closure Glaucoma!

COVID-19 News: In an era marked by the relentless challenges posed by the COVID-19 pandemic, a groundbreaking Chinese study has uncovered a startling revelation. This COVID-19 News report delves into a study conducted in the Huizhou region, in close collaboration between Huizhou Hospital Affiliated to Guangzhou Medical University and Sun Yat-sen University, Guangdong, that has illuminated an intriguing link between the SARS-CoV-2 virus and the development of acute angle-closure glaucoma (AACG).

Glaucoma Characteristics and Influencing Factors During the COVID-19 Pandemic
In the face of the pandemic, the impact on various aspects of healthcare is immeasurable. This particular study embarked on an exploration of the characteristics and risk factors associated with glaucoma during the COVID-19 crisis in Huizhou. The researchers delved into retrospective data gathered from outpatients with glaucoma, focusing on two distinct periods: the COVID-19 pandemic phase (Phase A: December 1, 2022, to January 19, 2023) and the pre-pandemic phase (Phase B: December 1, 2021, to January 19, 2022). The research aimed to examine the demographic makeup of the outpatients during both phases, dissect the features of glaucoma in patients who tested positive for COVID-19 during Phase A, and utilize multivariate logistic regression analysis to pinpoint factors influencing the emergence of AACG among Phase A patients.
The findings of the study were nothing short of revelatory. During Phase A, the proportion of patients with glaucoma surged significantly compared to Phase B, affecting both hospitals involved in the study. However, the analysis did not reveal any statistically significant disparities in age, gender, or region between patients with glaucoma during the two phases. What was noteworthy is that a high rate of COVID-19 positivity was associated with specific factors during Phase A, including old age, female gender, AACG, newly diagnosed glaucoma, and binocular involvement. In particular, females who tested positive for COVID-19, glaucoma that commenced after the COVID-19 diagnosis, and a history of medication use showed a pronounced inclination toward developing AACG during Phase A. The multivariable logistic regression analysis independently identified testing positive for COVID-19 as a potential risk factor for the onset of AACG.
The Impact of COVID-19 on Huizhou
The overarching narrative of the COVID-19 pandemic is one of profound transformation in the lives and well-being of the Chinese populace. This unprecedented global crisis first reared its head in Wuhan, China, in December 2019, eventually prompting the World Health Organization to declare it a global pandemic in March 2020. While many nations around the world were grappling with the zenith of the pandemic in 2021, China had already begun instituting measures to stave off resurgence, locally and internationally, from December 2019 to December 2022. However, as 2022 came to a close, domestic policies eased, leading to outbreaks in various Chinese regions, including the Huizhou area in Guangdong Province.
Between December 1, 2022, and January 19, 2023, Huizhou witnessed a significant COVID-19 outbreak that prompted a sea change in the behaviors and mental states of its residents. The repercussions of the pandemic's resurgence were multifaceted, manifesting in extended indoor activities, a decline in outdoor exposure, heightened reliance on over-the-counter cold medications for prevention, increased anxiety, and a pervasive reluctance to seek medical care unless it was deemed absolutely necessary.
Alarming Shifts in Outpatient Visits and Treatment Plans
The COVID-19 pandemic gave rise to substantial transformations in outpatient visits and the treatment of glaucoma. Specifically, the study brought to light the following significant shifts:
-Policy-Induced Changes: Government-imposed lockdowns and mobility restrictions played a pivotal role in shaping the landscape of outpatient visits.

-Increased Health Consciousness: With the fear of COVID-19, individuals became more alert to their health, resulting in greater proactiveness in seeking medical attention.
-Lifestyle Alterations: Changes in daily routines, along with a propensity for extended indoor activities, were observed to influence the onset of glaucoma.
-Medication-Related Factors: The study underscored the role of medications, especially those administered during the course of COVID-19 treatment, in potentially triggering acute glaucoma.
Understanding Acute Angle-Closure Glaucoma in the Context of COVID-19
Acute angle-closure glaucoma (AACG) represents a specific subset of angle-closure glaucoma, characterized by a sudden, severe increase in intraocular pressure. It is marked by debilitating symptoms, including intense eye pain, severe headaches, and acute visual impairment, necessitating immediate medical intervention to avert permanent vision loss.
Notably, the research pinpointed a strong association between AACG and COVID-19, particularly during the outbreak phase analyzed in the study. The study provided several key observations:
-Demographic Characteristics: Patients who tested positive for COVID-19 were more likely to develop AACG, particularly older individuals and females, many of whom experienced binocular involvement.
-AACG Onset After COVID-19 Diagnosis: AACG often manifested in patients who were diagnosed with COVID-19, indicating a temporal link between the two conditions.
-Medication Use: A history of medication use, particularly in the context of post-COVID-19 treatment, was associated with AACG, suggesting a potential connection between drug usage and the emergence of glaucoma.
The Enigmatic Connection Between COVID-19 and AACG
The study's findings underscore the association between testing positive for COVID-19 and the development of AACG, yet the precise underlying mechanisms remain elusive. However, the research posed several potential factors:
-Effect on the Eye Angle: The study posits that COVID-19 may influence the eye angle's function, potentially contributing to the onset of AACG.
-Medication-Related Factors: Certain medications employed in managing COVID-19 symptoms, including traditional Chinese medicine and cough suppressants, may indirectly serve as triggers for AACG.
-Infections and Eye Conditions: The research contemplates the possibility that COVID-19 may affect the eye's functionality, similar to other infections that can induce AACG.
In light of the study's limitations, such as its retrospective and descriptive nature and its geographical focus on Huizhou, it becomes clear that there is an imminent need for more comprehensive research into the impact of COVID-19 on eye health, especially in the context of glaucoma. Subsequent studies, encompassing a broader spectrum and collaborating across multiple centers, are essential to provide a more in-depth examination of acute glaucoma in patients afflicted with COVID-19.
In summation, the study conducted in the Huizhou region shines a spotlight on the profound link between testing positive for COVID-19 and the potential development of glaucoma, particularly AACG. This realization underscores the urgency of recognizing and addressing ocular complications that can emanate from COVID-19, thereby paving the way for strategies to anticipate and mitigate glaucoma in forthcoming waves of the pandemic. As the world continues to grapple with the multifaceted challenges posed by the enduring COVID-19 crisis, extensive research and a profound understanding of the pandemic's manifold effects on health remain critical.
The study findings were published in the peer reviewed Journal of Ophthalmology. (Hindawi)
