Unraveling the Puzzle of Central Serous Chorioretinopathy: Exploring Psychological Factors and Pathophysiological Mechanisms.

Central serous chorioretinopathy (CSCR) is a relatively common retinal disease involving the localized serous detachment of the neurosensory retina from the retinal pigment epithelium (RPE). Research suggests that individuals with a Type A personality, exhibiting traits such as competitiveness, urgency, aggression, and hostility, are significantly more prone to developing CSCR. Several studies have confirmed that a propensity to stress as well as different stressful events may predispose subjects to the development and recurrence of CSCR. Patients with CSCR are more depressive, report a higher level of anxiety and use more psychopharmacologic medications. Despite the research conducted on the topic, it remains unclear how a variety of psychological factors can contribute to dysfunction and pathological changes in the choroid and RPE. Some authors propose that increased levels of sympathetic neurotransmitters and glucocorticoids may alter the choroidal blood flow and increase the permeability of choriocapillaris in CSCR patients. It is generally accepted that hyperpermeable choroidal vessels are responsible for increased tissue hydrostatic pressure, which promotes RPE detachment, breaks the barrier function of the RPE and leads to subretinal fluid accumulation. Although the etiological factors and pathophysiological mechanisms have still not been fully clarified, CSCR is most likely a multifactorial disease involving disturbed interrelationships between biological and psychological factors. This comprehensive review aims to provide an up-to-date exploration of the psychological factors and pathophysiological mechanisms associated with CSCR.

Personality Traits, Stress, and Emotional Intelligence Associated with Central Serous Chorioretinopathy.

BACKGROUND The aim of the present study was to investigate the relationship between personality traits, stress, emotional intelligence, and central serous chorioretinopathy (CSCR). MATERIAL AND METHODS This prospective case-control study included 57 patients with acute CSCR and 57 age- and sex-matched controls with refractive errors. Inclusion criteria for CSCR group were acute unilateral onset of visual disturbances within 2 weeks until the first visit to the ophthalmologist and ophthalmoscopic finding of a round or oval macular detachment confirmed by optical coherence tomography as a dome-shaped serous neuroretinal elevation. RESULTS Using the Sixteen Personality Factor Questionnaire (16 PF), patients with CSCR achieved slightly higher scores on primary characteristics such as warmth (P=0.612) and perfectionism (P=0.137) when compared to the control subjects. Mean scores measured with the Social Readjustment Rating Scale (SRRS) were significantly higher in patients with CSCR (P=0.004), which means that these patients had notably elevated average reactivity to stressful life events. In addition, the number of patients with a high stress level was higher in the CSCR group than in the control group. Considering the level of emotional intelligence measured with the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF), patients with CSCR achieved significantly lower scores on well-being (P=0.003) and sociability (P=0.011) factors, as well as on total score (P=0.014). CONCLUSIONS A higher level of perceived stress is the most important psychological risk factor for CSCR. According to our results, a low level of emotional intelligence may be an additional factor that contributes to the occurrence of CSCR.

Concentrations of Selected Cytokines and Vascular Endothelial Growth Factor in Aqueous Humor and Serum of Diabetic Patients.

Purpose: To investigate the aqueous humor and serum levels of selected cytokines and vascular endothelial growth factor (VEGF) in diabetic patients, implicating their role in the pathogenesis of diabetic eye complications.Materials and methods:   Atotal of 65 patients (27 males and 38 females) who underwent cataract surgery were recruited into the study. The study group consisted of 30 cataract patients with type 2 diabetes mellitus, and this group was divided into two subgroups: 14 patients with diabetic retinopathy (DR group) and 16 patients without DR (NDR group). The control group consisted of 35 non-diabetic cataract subjects.Results: Patients in the DR group had significantly higher aqueous humor concentrations of interleukin (IL)-1ß, IL-6, IL-8, IL-10, monocyte chemotactic protein (MCP-1) and VEGF. Likewise, serum concentrations of IL-1ß, IL-6, IL-8, IL-12, TNF-α and IFN-γ were significantly higher in the DR group as compared to the controls. Aqueous humor concentrations of IL-1ß, IL-8, MCP-1 and VEGF were significantly higher in the DR group as compared with the NDR group.Conclusion: Our findings support the hypothesis that chronic inflammation and a disturbance of the immune system play important roles in the pathogenesis of diabetic cataract and DR.
