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.

Abstract Purpose: To assess choroidal thickness in patients with lipoid proteinosis versus healthy subjects using enhanced depth imaging optical coherence tomography. Methods: 40 eyes of 20 patients and the same number of age and sex-matched healthy individuals were enrolled. Comprehensive ocular examinations including measurement of best-corrected visual acuity, spherical equivalent values of refractive errors, and axial length were performed. Choroidal thickness at three points (subfoveal, 500 µm nasal and temporal regions) were measured. Results: The mean age was 15,68 ± 5,98 years in the patient group and 16,48 ± 5,69 years in the control group. Mean choroidal thickness was statistically significantly thicker at each point in patients with lipoid proteinosis compared to the healthy controls: subfoveal, temporal and nasal choroidal thickness measurements were 414,13 ± 53.88, 359.97 ± 64.75, 322.10 ± 56.74 in the study group; 341.60 ± 42.01, 329.55 ± 41.30, 295.44 ± 43.07 in the control group, respectively ( P < 0.05). Conclusion: Patients with lipoid proteinosis have thicker choroid compared to control eyes. Hyalin deposition and ensuing potential inflammation in the disease process may explain this finding.

66 healthy people (124 eyes) with different degrees of myopia and emmetropia were examined using enhanced depth imaging optical coherence tomography (EDI-OCT) using the “Spectralis OCT”. It was found that the choroid in subjects with medium and high degrees of myopia was significantly thinner than that in the control group. In the study, a negative correlation was found between the subfoveal choroidal thickness and the degree of myopia (r = -0.75, p < 0.0001). It was also found that the subfoveal choroidal thickness decreased for each diopter of myopia by approximately 18.03 μm.

Purpose. To investigate the effect of cataract surgery on subfoveal choroid thickness (SFCT) using enhanced-depth imaging optical coherence tomography (EDI-OCT). Materials and Methods. Relevant publications were searched systematically through various databases from inception to March 2018. The unit of choroidal thickness measurements is micrometers. Studies comparing SFCT before and after cataract surgery were retrieved. All qualified articles were analyzed using RevMan 5.3. Results. A total of 13 studies with 802 eyes from 646 patients were identified for inclusion. There was a significant increase of SFCT at 1 week (MD = 6.62, 95% CI: 1.20–12.05, P=0.02, I2 = 0%), 1 month (MD = 8.30, 95% CI: 3.20–13.39, P=0.001, I2 = 0%), and 3 months (MD = 8.28, 95% CI: 1.84–14.73, P=0.01, I2 = 0%) after cataract surgery. In subgroup analysis, SFCT in Asians and patients without nonsteroidal anti-inflammatory drugs (NSAIDs) in postoperative medication was significantly thicker (P<0.05). No statistically significant increase of SFCT was found in diabetic mellitus (DM) patients for 1 day (P=0.89), 1 week (P=0.59), 1 month (P=0.52), and 3 months (P=0.42) after cataract surgery. Conclusions. This meta-analysis suggested that SFCT increased since 1 week after the cataract surgery and the increase lasted for at least 3 months. Asians and patients without NSAIDs in postoperative medication were more likely to have a thicker SFCT after cataract surgery, whereas DM patients were less likely to increase in SFCT.

Abstract Background: The purpose of this study was to evaluate the macular choroidal thickness in obese children with and without insulin resistance (IR). Methods: Thirty-six patients with obesity and 26 healthy volunteers were included in this cross-sectional study. The choroidal thickness was measured with enhanced depth imaging optical coherence tomography (EDI-OCT) at the fovea and at positions 500 μm, 1000 μm, 1500 μm nasal and temporal to the fovea. The choroidal thickness measurements of the groups were compared and the correlation between the homeostasis model assessment of insulin resistance (HOMA-IR) and choroidal thickness values was evaluated. Results: The average choroidal thickness in the obese group was significantly lower than that of controls at locations 1000 μm (303.31±58.52 vs. 340.58±69.47, p=0.026) and 1500 μm (284.14±65.06 vs. 336.85±71.37, p=0.004) temporal to the fovea. A subgroup analysis depending on the presence of IR revealed that the choroidal thickness measurements at all positions were thinner in obese children without IR compared to children with IR and healthy controls. This thinning reached a statistical significance at locations 500 μm temporal, 1000 μm temporal and 1500 μm temporal to the fovea (p=0.03, p=0.009 and p=0.006; respectively). There was a moderate correlation between the choroidal thickness measurements and HOMA-IR values (r-values between 0.37 and 0.48; p<0.05). Conclusions: Our results suggest that obesity and IR may have an influence on the choroidal thickness in children. Longitudinal studies will clarify whether these choroidal changes are progressive and are a sign of microvascular dysfunction in childhood obesity.

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.
