Summary
This summary is machine-generated.Mental arithmetic stress significantly thickens the choroid (CT), a key eye layer. This finding suggests chronic mental stress may worsen myopia progression, impacting vision health.
Area Of Science
- Ophthalmology
- Neuroscience
- Physiology
Background
- Education-related stress is linked to myopia.
- Mental stress may affect ocular health.
- The impact of acute mental stress on choroidal thickness is not well understood.
Purpose Of The Study
- To investigate how mental arithmetic (MA) induced mental stress affects choroidal thickness (CT).
- To explore the relationship between acute psychological stress and ocular physiological changes.
Main Methods
- 33 participants (19-29 years) underwent swept-source optical coherence tomography (SS-OCT).
- Choroidal thickness (CT) was measured at baseline and during MA.
- Deep learning segmentation analyzed CT changes in 1mm and 3mm regions around the fovea.
Main Results
- Significant increases in choroidal thickness were observed during MA.
- Mean CT increase in the 1mm region (CT1mm) was 2.742 ± 7.098 μm (p=0.034).
- Mean CT increase in the 3mm region (CT3mm) was 3.326 ± 6.143 μm (p<0.001).
Conclusions
- Acute mental stress induces choroidal thickening.
- This suggests a potential link between chronic stress and myopia progression.
- Further research is needed to confirm the long-term effects of mental stress on myopia.

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
