“…In another study by Horozoglu et al, it was observed that there was no increase in choroidal thickness values in H. pylori positive patients without CSCR ( 38 ). Can et al reported that choroidal thickness values were found to be increased in adult patients with H. pylori infection and regression of choroidal thickness with treatment was shown ( 39 ). Contrary to the controversial results in the studies conducted in the adult age group, we think that the main factor in the formation of the statistical difference arises from the fact that aging and decreasing vascular elasticity and compliance.…”

Objectives: The aim of this study was to investigate the effect of Helicobacter pylori (H. pylori) infection on choroidal thickness (CT), retinal nerve fiber layer (RNFL) thickness, and ganglion cell (GCL+IPL) complex thickness in childhood cases of gastritis. Methods: A total of 104 eyes of 52 children were included in the study. Two groups were created: 54 eyes of 27 H. pylori gastritis cases (Group 1) and 50 eyes of 25 gastritis without H. pylori cases (Group 2), as confirmed by an endoscopic biopsy. The mean subfoveal, submacular, and peripapillary CT, RNFL thickness, and GCL+IPL complex thickness was measured using spectral domain optical coherence tomography. Results: The mean subfoveal CT values were significantly higher in Group 1 compared with Group 2 (p=0.042). The mean submacular CT and peripapillary CT measurements of the eyes in Group 1 was greater than that of Group 2, but the difference was not statistically significant (p>0.05). There was also no statistically significant difference between the GCL+IPL complex or RNFL thickness values of the groups (p>0.05). Conclusion: H. pylori is a common gastrointestinal infectious agent with asymptomatic carriers in the population. The role of this agent in ocular pathologies in adult patients has been the subject of many recent studies, but secondary ocular findings in patients with H. pylori gastritis in childhood have not yet been investigated. The results of this study showed that the subfoveal CT value was significantly greater in children with H. pylori gastritis.

“…As a metabolically active tissue, the retina consumes many nutrients and oxygen [11] . Among the body's blood vessels, the choroid has the highest blood flow per unit of tissue weight, which is responsible for supplying oxygen and nutrients to the retina [12][13] . Physiological conditions and systemic disorders can affect the retina or choroid [14][15] .…”

AIM: To evaluate the relationship of overweight and obesity with retinal and choroidal thickness in adults without ocular symptoms by swept-source optical coherence tomography (SS-OCT). METHODS: According to the body mass index (BMI) results, the adults enrolled in the cross-sectional study were divided into the normal group (18.50≤BMI<25.00 kg/m2), the overweight group (25.00≤BMI<30.00 kg/m2), and the obesity group (BMI≥30.00 kg/m2). The one-way ANOVA and the Chi-square test were used for comparisons. Pearson’s correlation analysis was used to evaluate the relationships between the measured variables. RESULTS: This research covered the left eyes of 3 groups of 434 age- and sex-matched subjects each: normal, overweight, and obesity. The mean BMI was 22.20±1.67, 26.82±1.38, and 32.21±2.35 kg/m2 in normal, overweight and obesity groups, respectively. The choroid was significantly thinner in both the overweight and obesity groups compared to the normal group (P<0.05 for all), while the retinal thickness of the three groups did not differ significantly. Pearson’s correlation analysis showed that BMI was significantly negatively correlated with choroidal thickness, but no significant correlation was observed between BMI and retinal thickness. CONCLUSION: Choroidal thickness is decreased in people with overweight or obesity. Research on changes in choroidal thickness contributes to the understanding of the mechanisms of certain ocular disorders in overweight and obese adults.
