Central serous chorioretinopathy (CSC) is a common retinal disease that causes vision loss worldwide. Studying the imaging characteristics of CSC is helpful for the differential diagnosis of diseases. This study analyzed the differences between acute and chronic CSC and provide related information.
PURPOSE
The aim of this study was to describe the optical coherence tomography features in patients with acute and chronic CSC.
METHODS
Sixty-two eyes of 56 patients with CSC were included in the study. Optical coherence tomography was performed to observe the image features. The photoreceptor outer-segment (PROS) thickness above the pigment epithelium detachment (PED) coinciding with the leakage point in fundus fluorescein angiography was measured and compared with the mean PROS thickness outside the PED in acute cases. The SPSS 23.0 software (IBM Co., Chicago, IL) was used for statistical analysis.
RESULTS
Of our 56 patients (62 eyes), 41 (73.21%) were male and 15 (26.79%) were female. There were 53 eyes (85.48%) with acute CSC and 9 eyes (14.52%) with chronic CSC. Besides other common features, the new feature of a high-reflection band in the outer nuclear layer was found to be limited to the macular detachment area. In acute cases, the mean PROS thickness above the retinal pigment epithelium layer protuberance coinciding with the leakage point was 22.7 ± 8.8 μm, which was less than the mean PROS thickness outside the PED at 64.3 ± 21.3 μm (P ≤ .001).
CONCLUSIONS
The high-reflection band in the outer nuclear layer within the serous neurosensory detachment limited to the macular area was a new finding in CSC patients. This finding can be used as an imaging feature to aid in the diagnosis of CSC.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:œdème papillaireMots-clés : pseudo-tumeur cérébrale Résumé : SIGNIFICANCE: Choroidal vascularity index measured by image binarization method from peripapillary optical coherence tomography sections has been found significantly lower in papilledema patients than healthy controls.
PURPOSE: The purpose of this study was to compare peripapillary choroidal parameters in papilledema patients
with control subjects.
METHODS: Peripapillary spectral domain optical coherence tomography scans of 34 patients with papilledema
and 34 healthy controls are acquired for the study. Images are binarized with the ImageJ software (National Institutes of Health, Bethesda, MD) to calculate total choroidal area, stromal area, luminal area, and choroidal vascularity index.
RESULTS: Total choroidal area, luminal area, and choroidal vascularity were significantly lower in papilledema patients compared with healthy controls on right (1.343 ± 0.286 vs. 1.694 ± 0.344, P < .001; 0.880 ± 0.209 vs.
1.167 ± 0.255, P < .001; 65.28 ± 2.99% vs. 68.68 ± 2.81%, P < .001, respectively) and left eyes
(1.376 ± 0.308 vs. 1.647 ± 0.339, P < .001; 0.899 ± 0.231 vs. 1.134 ± 0.237, P < .001; 64.92 ± 3.44 vs.
68.84 ± 3.23, P < .001, respectively). No difference was found between active and remitted stages of papilledema
in terms of choroidal parameters.
CONCLUSIONS: Peripapillary total choroidal area, luminal area, and choroidal vascularity index are significantly
reduced in patients with papilledema. These parameters might be beneficial tools for evaluating choroidal vascularity in papilledema quantitatively and differential diagnosis for optic disc edemaPermalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Tomographie par cohérence optiqueMots-clés : Rétinas glaucoma tomography, optical coherence Résumé : SIGNIFICANCE: Optical coherence tomography speckle is used here in an unconventional way as the indirect
source of information on tissue microstructure. The study reveals that the corneal speckle of glaucoma suspects
has a similar relationship between the parameters of scattering exhibited in glaucoma patients.
PURPOSE: The purpose of this study was to evaluate the potential of optical coherence tomography imaging of the
cornea in early diagnosis of glaucoma.
METHODS: Corneas of 64 subjects of three groups, including 18 primary open-angle glaucoma patients, 24 glaucoma suspects with normal levels of IOP and uncompromised visual field, and 22 age-matched controls, were imaged with spectral optical coherence tomography. A central region of interest in each optical coherence
tomography image visualizing the stroma was automatically extracted, and the intensity data within that region
were fit with the generalized gamma distribution. Its parameters describe the scatterer cross section and scatterer
density and indirectly assess corneal microstructure. In addition, subjects underwent measurements of IOP, visual
field, Heidelberg Retinal Tomography, retinal nerve fiber layer thickness, and biometry. Group means of all parameters were tested for equality. Within each group of subjects, correlation was evaluated between the statistical parameters of the corneal speckle.
RESULTS: Glaucoma suspects had statistically significantly different IOP, visual field parameters, mean retinal
fiber layer thickness, and central corneal thickness from those of glaucoma patients but not from those of the control group. The parameters of the corneal speckle were not significantly different between the groups, but they
showed a markedly higher and statistically significant coefficient of determination for glaucoma patients and suspects than that for the control group (0.927 and 0.707 vs. 0.336).
CONCLUSIONS: The results indicate that glaucoma suspects have similar relationship between the corneal scatterer cross section and scatterer density to that exhibited in the glaucoma patients but markedly different from that
of healthy controlsPermalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Tomographie par cohérence optiqueMots-clés : glaucoma diagnosis therapeutics disease management tomography, optical coherence fibres nerveuses rétiniennes circumpapillary retinal nerve fiber Résumé : SIGNIFICANCE
Assessing and managing glaucoma are a complicated process in which experience plays a key role in decision making. Although advanced glaucoma is more easily diagnosed, patients with early glaucoma or who present with suspicious findings are more complicated. A need to aid clinicians in the decision-making process exists.
PURPOSE
The purpose of this study was to assess the impact of en face ocular coherence tomography images to clinical decision making when added to standard presentations of circumpapillary retinal nerve fiber layer thickness and automated perimetry.
METHODS
Thirty participants from two centers presenting either as a glaucoma suspect or for an initial glaucoma evaluation were enrolled. Six masked investigators were given standard presentations of circumpapillary retinal nerve fiber layer thickness and perimetry. They were asked if glaucomatous damage was present as well as a recommended plan of management on 5-point Likert scales. They were then given en face images of the retinal nerve fiber layer in three different presentations coupled with the standard presentation, and the questions were repeated. An intraclass correlation coefficient (ICC) was generated.
RESULTS
The masked investigators had moderate agreement from the standard presentation for assessment (ICC = 0.67 [95% confidence interval {CI}, 0.54 to 0.80] and ICC = 0.69 [95% CI, 0.52 to 0.80], respectively), as well as with the addition of the en face images (ICC = 0.69; 95% CI, 0.56 to 0.81). The en face images tended to change decisions in both assessment and plan toward likely to have glaucoma and likely to start treatment.
CONCLUSIONS
The addition of en face images to a standard presentation has an impact on clinical decision making. Although en face images seem to influence the decision toward likely to have glaucoma and likely to treat, it is unclear if this leads to a more accurate decision. Further investigations seem warranted to assess sensitivity and specificity of this approach.

[Thésaurus HELB]:Optique:biometrie optiqueMots-clés : validité des mesures Résumé : SIGNIFICANCE: The validity of measurements of OA-2000 (Tomey, Nagoya, Japan), a new swept-source optical coherence tomography–based biometer, was evaluated in comparison with IOLMaster 500 (Carl Zeiss Meditec AG, Jena, Germany) as a reference method for optical biometry in cataract patients. PURPOSE: This article compares the validity of measurements between OA-2000 and IOLMaster 500. METHODS: In this cross-sectional study, axial length, lens thickness, anterior chamber depth, and keratometry readings were obtained by the OA-2000 and IOLMaster 500. Two measurements were taken by each method. Patients in which any one of the biometry methods could not be performed owing to severity of the cataract were excluded from the study. Repeatability of measurements was presented by coefficient of variation, and Bland-Altman method was used for evaluating the agreement between the two biometers. RESULTS: Fifty-eight eyes of 58 cataract patients with mean ± standard deviation age of 61.4 ± 8.3 years were included in this study. Intraclass correlation ranged from 0.898 to 0.901 and showed good to excellent reliability. It was good for keratometry 1 (0.898) and excellent for keratometry 2 (0.992), axial length (0.999), and anterior chamber depth (0.901). Bland-Altman analysis showed good agreement between the swept-source optical coherence tomography and partial coherence interferometry devices for axial length, anterior chamber depth, and mean keratometry, with narrow 95% limits of agreement (−0.09 to 0.1mm, −0.33 to 0.54mm, −0.97 to 1.03 D, respectively), and also indicated small mean difference (0.01 for axial length, 0.11 for anterior chamber depth, 0.03 for mean keratometry, respectively) for all comparisons. CONCLUSIONS: OA-2000 as a new swept-source optical coherence tomography has an excellent repeatability for measurement of biometric data in cataract patients, comparing with the standard partial coherence interferometry biometer (IOLMaster 500).
