Purpose.We aimed to investigate retinal and choroidal thickness in the eyes of patients with Fuchs’ uveitis syndrome (FUS).Methods.Fifteen patients with unilateral FUS and 20 healthy control subjects were enrolled. Spectral domain optical coherence tomography (Spectralis HRA+OCT, 870 nm; Heidelberg Engineering, Heidelberg, Germany) was used to obtain retinal and choroidal thickness measurements. The retinal nerve fiber layer (RNFL) thickness, macular thickness, and choroidal thickness of the eyes with FUS were compared with the unaffected eye and the eyes of healthy control subjects.Results.The mean choroidal thickness at fovea and at each point within the horizontal nasal and temporal quadrants at 500 μm intervals to a distance of 1500 µm from the foveal center was significantly thinner in the affected eye of FUS patients compared with the unaffected eye of FUS patients or the eyes of healthy control subjects. However, there were no significant differences in RNFL or macular thickness between groups.Conclusions.Affected eyes in patients with FUS tend to have thinner choroids as compared to eyes of unaffected fellow eyes and healthy individuals, which might be a result of the chronic inflammation associated with the disease.

Purpose. To evaluate choroidal thickness in patients with coeliac disease (CD) using spectral domain optical coherence tomography (SD-OCT) and to compare the results to normal eyes. Methods. Seventy patients with CD and 70 healthy controls were included in this prospective, comparative study. All participants underwent a complete ophthalmologic evaluation and SD-OCT. Subfoveal, nasal (nasal distance to fovea 500 μm, 1000 μm, and 1500 μm), and temporal (temporal distance to fovea 500 μm, 1000 μm, and 1500 μm) choroidal thickness measurements were performed using SD-OCT. Results. There were no significant differences in sex, ages, and axial lengths between the groups (p=1.0, p=0.601, p=0.314, respectively). The mean choroidal thickness measurements at all predefined measurement point areas were higher in the coeliac group than in the healthy controls (p<0.001). Of all patients with coeliac disease (70 eyes of 70 patients), 64 eyes (84.2%) had uncomplicated pachychoroid (UCP), one eye had pachychoroid pigment epitheliopathy (PPE), and five eyes in the UCP group had PPE in fellow eyes. Conclusion. It is probable that systemic inflammation in coeliac patients causes the enlargement of choroidal vessels and increasing choroidal thickness. PPE, which is believed to be the precursor of central serous chorioretinopathy, can be observed in coeliac patients.

Objective The objective of the study was to describe and evaluate the subfoveal choroidal thickness (SFCT) in the fellow eyes of patients with central serous chorioretinopathy (CSC) using swept source optical coherence tomography (SS-OCT). Methods This was a transversal, retrospective, and observational study. The SFCT was measured in patients with unilateral CSC using SS-OCT. The choroidal thickness in symptomatic and fellow eyes was measured using the attached measuring software in SS-OCT. The SFCT dimension was obtained from the horizontal section under the foveal center from the OCT data and these data were analyzed. Results The mean age of subjects undergoing imaging SS-OCT was 44.23 years old (standard deviation, 11.57). 30 out of 60 patients (63.3%) were men, and 20 (33.3%) patients had acute clinical disease. The median choroidal thicknesses of the affected eyes were greater than those of the unaffected fellow eyes (P = 0.06). The choroidal thickness measured in 120 eyes of (60 patients) was 421 µm (interquartile range 352–490), which was greater than the choroidal thickness reported in normal eyes. Conclusions The measuring of the choroidal thickness using SS-OCT is useful as a non-invasive technique to evaluate the subclinical choroidal abnormalities in CSC.

Our study examined the choroidal thickness profile of children with myopic anisometropic amblyopia and compared the thickness with the fellow eyes. The choroidal thickness was measured with the enhanced depth imaging with spectral-domain optical coherence tomography. Manual segmentations of the choroid were performed on a 25-raster horizontal scan. The choroidal thickness measurements of the 9 subfields defined by the Early Treatment Diabetic Retinopathy Study (ETDRS) were evaluated. The mean spherical equivalent of the amblyopic eyes was -10.80 ± 0.41 D and the fellow eyes was -4.40 ± 2.05 D. The mean best corrected visual acuity of the amblyopic eyes and the fellow eyes were 0.94 ± 0.27 and 0.14 ± 0.05 logMAR respectively. The amblyopic eyes have longer axial length (26.46 ± 0.44 mm) compared to the fellow eyes (23.59 ± 1.18 mm). The average subfoveal choroidal thickness was 124.30 ± 40.71 µm in the amblyopic eyes and 246.80 ± 58.63 µm in the fellow eyes. The horizontal and vertical distribution pattern of choroidal thickness in amblyopic eyes was different from the fellow eyes. In amblyopic eye the choroidal thickness reduced from the temporal region to the nasal region. The fellow eyes had thickest choroid at the subfoveal area, followed by the temporal region and nasal region. In conclusion, the choroid was thinner in the amblyopic eyes than that of the fellow eyes at all regions.

Purpose To evaluate the alterations in mean central choroidal, central macular, and disk retinal nerve fiber layer (RNFL) thickness measured by optical coherence tomography (OCT) during Valsalva maneuver among patients with high refractive errors. Methods A total of 60 high myopic (≥-6.0 D) and 50 high hyperopic (≥ + 3.0 D) eyes of 58 patients aged 19-65 years with visual acuity of 20/20 and without any ophthalmologic or systemic diseases were evaluated by OCT before and after the Valsalva maneuver. The choroidal thickness was measured with enhanced depth imaging OCT method. Central macular thickness, disk RNFL thickness, and axial length were also assessed. Results Mean choroidal thickness increased significantly from 275.0 ± 27.2 μm at rest to 279.8 ± 31.6 μm after Valsalva maneuver in high myopic patients, and from 308.2 ± 27.3 μm to 313.6 ± 28.5 μm in high hyperopic patients (p<0.01 for each). A significant negative correlation of the choroidal thickness was noted with axial length (r = -0.509, p<0.01) and age (r = -0.224, p = 0.01) in the overall study population. Mean central macular thickness was 242.9 ± 44.4 μm and 254.0 ± 22.8 μm, while mean disk RNFL thickness was 81.6 ± 12.4 μm and 98.4 ± 13.3 μm in high myopic and hyperopic patients, respectively. Valsalva maneuver was not associated with significant change in central macular or disk RNFL thickness. Conclusions Significant association of Valsalva maneuver with an increase in choroidal thickness was noted among patients with high degree of myopia and hyperopia. Our findings emphasize the likelihood of increase in choroidal volume due to venous distension to be responsible for the increase observed in choroidal thickness after Valsalva maneuver.

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.

AbstractObjective:To investigate choroidal thickness using enhanced-depth imaging optical coherence tomography in paediatric patients with adenotonsillar hypertrophy, with comparison to healthy children, three months after adenotonsillectomy.Methods:The patients were assigned to three groups: an adenotonsillar hypertrophy group, an adenotonsillectomy group and a healthy control group. In all groups, subfoveal, temporal and nasal choroidal thickness measurements were taken.Results:In the subfoveal, temporal and nasal regions, choroidal tissue was found to be significantly thinner in adenotonsillar hypertrophy children than healthy children (p = 0.012, p = 0.027 and p = 0.020). The subfoveal and temporal choroidal thickness measurements of adenotonsillar hypertrophy group cases were significantly decreased compared to those in the adenotonsillectomy group (p = 0.038 and p = 0.048).Conclusion:There was a significant association between decreased choroidal thickness and adenotonsillar hypertrophy. Adenotonsillar hypertrophy may play an important role in decreased choroidal thickness.

The Relationship

Ischemic stroke is one of the most common causes of death worldwide and is most often caused by thrombotic processes. We investigated the changes in hsCRP and homocysteine levels, two of these risk factors, during the acute period of ischemic stroke and evaluated the relationship between these levels and the short-term prognosis. HsCRP and homocysteine levels were measured at the 2nd, 5th, and 10th days in forty patients admitted within second of an ischemic stroke. The clinical status of the patients was simultaneously evaluated with the Scandinavian stroke scale. The results were compared with 40 healthy control subjects whose age and sex were matched with the patients. The mean hsCRP levels of the patients were9.4±7.0mg/L on the 2nd day,11.0±7.4mg/L on the 5th day, and9.2±7.0mg/L on the 10th day. The mean hsCRP level of the control subjects was1.7±2.9mg/L. The mean hsCRP levels of the patients on the 2nd, 5th, and 10th days were significantly higher than the control subjects (P<.001). The patients' mean homocysteine levels were40.6±9.6μmol/L on the 2nd day,21.7±11.1μmol/L on the 5th day, and20.7±9.2μmol/L on the 10th day. The mean homocysteine level of the control subjects was11.2±1.1μmol/L. The homocysteine levels of the patients were higher than the control subjects at all times (P<.01). In conclusion, patients with stroke have a higher circulating serum hsCRP and homocysteine levels. Short-term unfavorable prognosis seems to be associated with elevated serum hsCRP levels in patients with stroke. Although serum homocysteine was found to be higher, homocysteine seems not related to prog nosis.

Purpose To evaluate choroidal thickness (CT) and its relationship with retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer thickness (GCIPLT) in glaucomatous, preperimetric glaucomatous, and healthy eyes using swept-source optical coherence tomography (SS-OCT). Methods Fifty eyes with primary open-angle glaucoma, 20 eyes with preperimetric glaucoma, and 20 age-matched healthy eyes were enrolled. Three-dimensional wide-field (12 × 9 mm) images were obtained using a SS-OCT instrument. Peripapillary CT and RNFL thickness, as well as macular CT and GCIPLT, were recorded. The correlation of the CT with nerve fiber layer and GCIPLT measurements was assessed. The association between CT and potential confounding variables including age, sex, axial length, intraocular pressure, and central corneal thickness was also examined. Results Mean peripapillary CTs were 111.7 ± 41.7, 127.7 ± 40.1, and 120.8 ± 35.4 μm in glaucomatous, preperimetric glaucomatous, and normal eyes, respectively. There was statistically significant but weak correlation for the mean RNFL and mean peripapillary CT in glaucomatous subjects (r = 0.341, p = 0.04). There was a significant correlation between RNFL thickness and peripapillary CT in 1, 2, 5, and 6 clock hours of glaucomatous eyes (r = 0.410, p = 0.005; r = 0.316, p = 0.03; r = 0.346, p = 0.02; r = 0.35, p = 0.04, respectively). Mean macular CT was 181.5 ± 70.5, 187.4 ± 65.5, and 185.4 ± 76.4 μm in glaucomatous, preperimetric glaucomatous, and healthy eyes, respectively (p = 0.7). There was no statistically significant correlation between the mean GCIPLT and mean macular CT in all subjects (p>0.05). Conclusions Choroidal thinning and its correlation with other parameters in patients with glaucoma should be further investigated with the proprietary software of SS-OCT.

The Mean

This prospective cross-sectional study attempted to determine both the usefulness of the serum intercellular adhesion molecule-1 (ICAM-1) as a biomarker for pulmonary artery hypertension secondary to congenital heart disease and the nature of this marker's association with catheter angiographic findings. Our study included a total of 70 male and female children, comprising 30 patients with both pulmonary artery hypertension and congenital heart disease, 20 patients with congenital heart disease alone, and 20 healthy control subjects. Levels of ICAM-1 in plasma samples from all groups were measured by the enzyme-linked immunosorbent assay method. Cardiac catheterization was also performed in all patients. The mean serum ICAM-1 levels in pediatric patients who had congenital heart disease with and without pulmonary artery hypertension were 349.6 ± 72.9 ng/mL and 312.3 ± 69.5 ng/mL, respectively (P=0.002). In healthy control subjects, the mean serum ICAM-1 level was 231.4 ± 60.4 ng/mL. According to the results of this study, the ICAM-1 level of the pulmonary artery hypertension group was significantly higher than those of the congenital heart disease group and the healthy control group. Correlation analysis showed that ICAM-1 level was correlated with systolic and mean pulmonary artery pressures (r=0.62, P=0.001; r=0.57, P=0.001)—which are 2 important values used in diagnosis of pulmonary artery hypertension. Moreover, receiver operating characteristic analysis yielded consistent results for the prediction of pulmonary artery hypertension. Therefore, we conclude that ICAM-1 has potential use as a biomarker for the diagnosis and follow-up of pulmonary artery hypertension.
