الوصف: Purpose: To evaluate the diagnostic accuracy of a novel optical coherence tomography texture-based en face image analysis (SALSA-Texture) that requires segmentation of only 1 retinal layer for glaucoma detection in eyes with axial high myopia, and to compare SALSA-Texture with standard macular ganglion cell-inner plexiform layer (GCIPL) thickness, macular retinal nerve fiber layer (mRNFL) thickness, and ganglion cell complex (GCC) thickness maps. Design: Comparison of diagnostic approaches. Methods: Cross-sectional data were collected from 92 eyes with primary open-angle glaucoma (POAG) and 44 healthy control eyes with axial high myopia (axial length >26 mm). Optical coherence tomography texture en face images, developed using SALSA-Texture to model the spatial arrangement patterns of the pixel intensities in a region, were generated from 70-μm slabs just below the vitreal border of the inner limiting membrane. Areas under the receiver operating characteristic curves (AUROCs) and areas under the precision recall curves (AUPRCs) adjusted for both eyes, axial length, age, disc area, and image quality were used to compare different approaches. Results: The best parameter-adjusted AUROCs (95% confidence intervals) for differentiating between healthy and glaucoma high myopic eyes were 0.92 (0.88-0.94) for texture en face images, 0.88 (0.86-0.91) for macular RNFL thickness, 0.87 (0.83-0.89) for macula GCIPL thickness, and 0.87 (0.84-0.89) for GCC thickness. A subset analysis of highly advanced myopic eyes (axial length ≥27 mm; 38 glaucomatous eyes and 22 healthy eyes) showed the best AUROC was 0.92 (0.89-0.94) for texture en face images compared with 0.86 (0.84-0.88) for macular GCIPL, 0.86 (0.84-0.88) for GCC, and 0.84 (0.81-0.87) for RNFL thickness (P ≤ .02 compared with texture for all comparisons). Conclusion: The current results suggest that our novel en face texture-based analysis method can improve on most investigated macular tissue thickness measurements for discriminating between highly myopic ...

الوصف: Aim: Nasal obstruction due to nasal septum deviation is associated with systemic diseases such as cardiopulmonary disease, neurological and vascular problems. But the effect of pure nasal deviation on the ocular system has not been precisely investigated. The aim of this study was to analyze the association of nasal septal deviation with ocular examination findings. Material and Methods: Twenty-seven adult patients underwent septoplasty and 31 controls were included in the study. The study group was conducted on patients with pure nasal septum deviation which is significantly obstructing the nasal airway (>50%). In ophthalmological examination; peripapillary retinal nerve fiber layer, macular and choroidal thickness measurements were obtained. The examination findings were compared between the study and control groups. Results: The mean macular thicknesses at nasal-500?m were 305.89±32.79 and 287.87±25.00 in the study and control groups, respectively (p=0.021). The mean macular thicknesses at nasal-1000?m were 353.04±21.28 and 341.16±17.97 in the study and control groups, respectively (p=0.025). The mean thickness of choroid was statistically significantly different at central (p=0.036) and peripheral measurements; nasal-500?m (p=0.020); nasal-1000?m (p=0.001); nasal-1500?m (p<0.001); temporal-500?m (p=0.023) and temporal-1000?m (p=0.045). No statistically significant difference was found between the two groups according to ocular tension, thickness of cornea, keratometry, anterior chamber depth, axial length of cornea, and retinal nerve fiber layer thickness. Conclusion: This is one of the pioneer studies evaluating the ocular examination findings in patients with nasal septum deviation. Our results indicate the increased thickness of both macula and choroid in patients with nasal septum deviation. © 2022, Duzce University Medical School. All rights reserved.

الوصف: Purpose: To provide consensus on the clinical use of intravitreal dexamethasone (DEX) implant for the treatment of diabetic macular edema (DME) in Turkey. Methods: A panel of 22 retina experts prepared 77 statements of recommendation, and 80 retinal specialists practicing in Turkey were chosen to vote either in support or against each one. A Delphi-based method was used through which the ophthalmologists were able to view all of the results anonymously after two rounds and modify their subsequent answers. The survey was conducted via a mini website, and statements without consensus were resent to the specialists with the latest vote results a week later. Results: A total of 72 ophthalmologists answered the first and second round questions. After the first stage, consensus was achieved on 55 of the statements, leaving 22 without agreement. After the second stage, consensus was reached on 11 of the remaining statements. Strong consensus was achieved on statements regarding the etiopathogenesis of DME and the first-line indications and safety of the DEX implant procedure. The panel recommended the use of DEX implant for patients with an arterial thromboembolic event in the last three months and also agreed that pro re nata DEX implant treatment not only provides better outcomes for DME patients but also reduces the treatment burden for those who could not receive an adequate number of anti-vascular endothelial growth factor (VEGF) injections. Conclusion: This study provides clinical consensus and recommendations about the use of DEX implant in the clinical practice of DME management in Turkey. © The Author(s) 2022.

الوصف: Purpose. Our aim was to evaluate the ultrasound (US) elastography of ocular and periocular structures in high myopia. Methods. There were 20 eyes of 20 high myopic patients in the study group, whereas there were 20 eyes of 20 age- and sexmatched healthy participants in the control group. The eyes in the study group had myopia greater than j5.0 diopters and had axial length (AL) greater than 25.0 mm. The US elastography measurements were performed with the LOGl ? Q E9 Ultrasound Elastography. The elastography values of anterior vitreous, posterior vitreous (PV), retina-choroid-sclera complex (RCS), and retrobulbar fat tissue (RF) were measured in each eye. Results. Anterior vitreous US elastography values were similar in both groups (p = 0.17), whereas PV is more elastic in high myopic eyes (p = 0.01). There was a moderate negative correlation between AL and RCS/RF elastography ratio (r = j0.35, p = 0.03) and a positive correlation between refractive error and RCS/RF elastography ratio (r = 0.36, p = 0.02). Conclusions. High myopia is associated with more elastic PV. Elasticity of posterior RCS increases as the AL increases. © 2015 American Academy of Optometry.

الوصف: Purpose: To assess the relationship of ocular pulse amplitude with eye structures and systemic blood pressure in healthy subjects. Material and Method: Fifty-one healthy subjects were included in the study. Ocular pulse amplitude measurement by Pascal dynamic contour tonometry, corneal pachymetry, axial length, anterior chamber depth, systolic and diastolic blood pressure measurements were performed in addition to routine ophthalmologic examination. The factors related to ocular pulse amplitude were statistically evaluated. Results: The mean age of the patients was 30.98±14.4 (range: 16-66) years. Of 51 patients, 14 (27.5%) were male and 37 (72.5%) were female. The mean ocular pulse amplitude, axial length, anterior chamber depth, corneal pachymetry, systolic and diastolic blood pressure were as follows: 2.4±0.8mmHg, 23.4±0.8 mm, 3.2±0.3 mm, 547.2±30.7 µm, 118.2±8.8 mmHg, 76.8±4.6 mmHg. Correlation analysis showed significant association between ocular pulse amplitude and intraocular pressure (p=0.000). The associations of ocular pulse amplitude with age, gender, corneal pachymetry, anterior chamber depth, and systolic and diastolic blood pressure were not significant. Linear regression analysis showed that axial length and intraocular pressure independently affected ocular pulse amplitude. Low ocular pulse amplitude was associated with low intraocular pressure and long axial length. Discussion: Ocular pulse amplitude was significantly associated with intraocular pressure and axial length but not with age, gender and anterior eye structures.

الوصف: PURPOSE. The purpose of this study was to prospectively investigate the association between retinopathy of prematurity (ROP) and ocular growth in premature infants during the earliest weeks of life. METHODS. Premature infants in the national ROP screening program were recruited and examined at 1-or 2-week intervals between 30 and 38 weeks of postmenstrual age. One hundred infants with gestational age (GA) between 24 and 35 weeks (30.04 + 2.13), and birth weight (BW) between 550 and 2060 g (1251.45 + 317.19) were included in the study. At each examination, the presence, stage, and zone of ROP were recorded along with axial length (AL), central corneal thickness (CCT), and weight gain. Biometric parameters were measured by A-scan biometry. Study variables included GA, BW, AL, CCT, weight gain, relative weight (RW), and dif_AL, dif_CCT, and dif_weight, which are the differences between two consecutive recordings of the same infant. Multiple regression analysis models were used to determine the association between the study variables and ROP. RESULTS. dif_AL, dif_CCT, and RW were the most appropriate variables to detect the optimal threshold points that discriminate ROP: weekly increase of AL < 0.095 mm, weekly reduction of CCT < 0.5 μm, or weekly weight gain < 7% is associated with ROP development. CONCLUSIONS. ROP is associated with delayed ocular development, as eyes of premature infants with ROP have shorter axial lengths and thicker corneas than eyes of premature infants without ROP. The association of AL, CCT, and weight gain with ROP could be of value for future development of predictive models for ROP. © 2019 The Authors.

الوصف: Purpose. Our aim was to evaluate the ultrasound (US) elastography of ocular and periocular structures in high myopia. Methods. There were 20 eyes of 20 high myopic patients in the study group, whereas there were 20 eyes of 20 age- and sexmatched healthy participants in the control group. The eyes in the study group had myopia greater than j5.0 diopters and had axial length (AL) greater than 25.0 mm. The US elastography measurements were performed with the LOGl ? Q E9 Ultrasound Elastography. The elastography values of anterior vitreous, posterior vitreous (PV), retina-choroid-sclera complex (RCS), and retrobulbar fat tissue (RF) were measured in each eye. Results. Anterior vitreous US elastography values were similar in both groups (p = 0.17), whereas PV is more elastic in high myopic eyes (p = 0.01). There was a moderate negative correlation between AL and RCS/RF elastography ratio (r = j0.35, p = 0.03) and a positive correlation between refractive error and RCS/RF elastography ratio (r = 0.36, p = 0.02). Conclusions. High myopia is associated with more elastic PV. Elasticity of posterior RCS increases as the AL increases. © 2015 American Academy of Optometry.
