The Impact

Purpose To assess the impact of metabolic syndrome (MetS) on the peripapillary choroidal thickness (PPCT) and to characterize the PPCT in a Portuguese population. Methods This prospective study included 104 eyes. Detailed medical and ophthalmic examinations were performed; the PPCT was measured by spectral-domain optical coherence tomography (SD-OCT) using enhanced depth imaging (EDI) modality. The PPCT changes with MetS, as well as with other clinical and demographic factors, were investigated. Results The mean PPCT was 142.4 ± 54.0 µm (58-303 µm); it was thickest superiorly, followed by the temporal, nasal, and inferior sectors. The PPCT was significantly associated with axial length (p<0.001), age (p = 0.001), intraocular pressure (IOP) (p = 0.041), weight (p = 0.015), and arterial hypertension (p = 0.044). The presence of MetS was associated with thinner PPCT in all sectors, being statistically significant in the temporal (p = 0.032) and inferotemporal (p = 0.034) sectors. Conclusions The choroidal thickness was significantly less in temporal and inferotemporal sectors in patients with MetS than in controls. This may suggest vascular insufficiency around the optic nerve head.

Abstract Purpose: To evaluate macular, peripapillary choroidal thickness and retinal nerve fiber layer (RNFL) thickness in different trimesters and compare the measurements with those of healthy non-pregnant women. Methods: A prospective comparative study included 45 healthy pregnant women in first trimester, 90 women in second, 45 women in third trimesters and 45 healthy no-pregnant women as the control group. Macular choroidal thickness was measured at the subfoveal, 1mm temporal and 1mm nasal to the fovea using enhanced depth imaging optical coherence tomography (EDI-OCT). Peripapillary choroidal thickness and RNFL thickness parameters were automatically calculated by the Spectralis OCT. These parameters were analyzed among groups. Results: The subfoveal, temporal and nasal choroidal thickness were all significantly thicker in second trimesters, comparing with those parameters in first, third trimesters and the control group (all P<0.05). The peripapillary choroidal thickness was significantly increased at temporal, nasal, nasal inferior, temporal inferior and global positions during pregnancy among the 4 groups (all P<0.05). The RNFL thickness was also significantly increased in pregnant women at nasal superior and nasal inferior quadrants.Conclusions: Our results suggested that macular choroidal thickening appeared in second trimester. And peripapillary choroidal thickness and RNFL thickness also became thickening in pregnant women comparing with no-pregnant women as a whole.

Background/Aim: Pseudoexfoliation (PSX) syndrome is associated with blood flow disturbances; however, its exact effect on choroidal blood flow and thickness remains to be elucidated. This study compared subfoveal choroidal thickness in normal eyes and in eyes with PSX using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: This prospective, cross-sectional study included 35 eyes of 35 patients (20 males, 15 females) with unilateral or bilateral PSX and 26 eyes of 26 healthy volunteers (13 males, 13 females). Besides a comprehensive ocular and physical examination, all subjects underwent EDI-OCT examination using an Optovue RTVue OCT device (Optovue Inc., Fremont, Calif., USA). Results: The mean choroidal thickness (CT) and ocular perfusion pressure (OPP) were lower in the PSX group than in the healthy controls (249.4 ± 46.3 vs. 282.5 ± 55.8 µm, p = 0.014 and 40.7 ± 5.8 vs. 44.3 ± 4.3 mm Hg, p = 0.007, respectively). In addition, both systolic blood pressure and diastolic blood pressure measurements were lower among the PSX patients. However, no correlation was found between CT and OPP. Conclusion: The findings of this study suggest that PSX is associated with an overall thinning of the subfoveal choroid and a significant decrease in OPP. Future studies are warranted to further examine these relations.
