Introduction This study aims to detect changes in choroidal thickness and retinal nerve fiber layer (RNFL) thickness in acute stage brucellosis. Methods Fnewly diagnosed patients with acute brucellosis and 19 healthy individuals as control group were included in the study. Choroidal thickness and RNFL thickness were measured using the Spectral Domain Cirrus OCT Model 400 (Carl Zeiss Meditec, Jena, Germany) for each participant in the patient and control group. Results In the brucella group, in the right eyes, the mean nasal choroidal thickness was 272.77 ± 50.26 μm ( p = 0.689), the mean subfoveal choroidal thickness was 321.14 ± 33.08 μm ( p = 0.590), the mean temporal choroidal thickness was 278.86 ± 48.84 μm ( p = 0.478), and the mean RNFL thickness was 90.43 ± 8.93 μm ( p = 0.567). In the left eyes, the mean nasal choroidal thickness was 282.29 ± 48.93 μm ( p = 0.715), the mean subfoveal choroidal thickness was 316.79 ± 39.57 μm ( p = 0.540), the mean temporal choroidal thickness was 284.93 ± 50.57 μm ( p = 0.392), and the mean RNFL thickness was 92.64 ± 8.95 μm ( p = 0.813). Conclusion No difference was found between the control and the brucella groups regarding to all choroidal regions and RNFL thickness.

Abstract Background Retinal and choroidal blood vessels are involved in many systemic diseases because they are complex vascular systems. Chronic obstructive pulmonary disease is considered as an inflammatory disease that affects many systems and coexists with several co-morbidities. Systemic inflammation and hypoxia affect the macula, choroid, retinal nerve fiber layer (RNFL), and blood vessels. Ocular co-morbidities have been detected in COPD patients. These can be quantitatively and qualitatively evaluated by Spectral Domain Optical Coherence Tomography (SD-OCT). Enhanced depth imaging OCT (EDI-OCT) is a quite new technique that utilizes light with an extended wavelength. An apparent relation has been found between chronic pulmonary disease and low corneal endothelial cell density preoperatively. So this work aimed to assess the impact of COPD severity grading and oxygen saturation on retinal nerve fiber layer thickness and subfoveal choroidal thickness. Results This was a case-control study, recruited 50 COPD patients and another 50 healthy volunteers as a control group. Measuring the thickness of the RNFL (superior, inferior, nasal, and temporal) in the four quadrants as well as the subfoveal choroidal thickness was done to both groups. The RNFL thickness in all quadrants and the SFCT in the COPD group were statistically significantly thinner in comparison to the control group. The RNFL thickness (mean) was 79.16 ± 10.49 μm compared to 96.30 ± 4.66 μm in the control group (p value 0.001). The SFCT (mean) was 213.12 ± 25.61 μm compared to 354.62 ± 53.82 μm in the control group (p value 0.001). The degree of thinning of the RNFL (superior, inferior, and temporal) and the SCFT was related to COPD (GOLD) stages severity (p value 0.001). Nasal RNFL was thinned out in all stages of COPD (GOLD) but with no statistical significance (p value 0.264). Conclusion The choroid and retina seem to be of the affected tissues during the progressive inflammatory course of COPD. Ocular pathologies should be evaluated in patients with systemic hypoxia. The eye examination for COPD patients can be carried out via a non-invasive procedure such as the OCT and the changes in the RNFL and SFCT thickness could be used as indicators for the severity of COPD.

Objectives: Evaluation of the peripapillary retinal nerve fiber layer thickness, subfoveal choroidal thickness, and retinal vessel caliber measurements in children with thalassemia minor. Methods: In this cross-sectional and comparative study, 30 thalassemia minor patients and 36 controls were included. Heidelberg spectral domain optical coherence tomography was used for peripapillary retinal nerve fiber layer thickness, subfoveal choroidal thickness, and retinal vessel caliber measurements. Results: There was no statistically significant difference in retinal nerve fiber layer thickness and subfoveal choroidal thickness between the two groups ( p > 0.05). There was no correlation between retinal nerve fiber layer thickness and hemoglobin values. Both the arterioral and venular calibers were higher in thalassemia minor group ( p < 0.05). Conclusion: There is increased retinal arterioral and venular calibers in children with thalassemia minor compared with controls.
