| 1 | Comparison of Goldmann applanation tonometry,rebound tonometry and dynamic contour tonometry in normal and glaucomatous eyes显示文摘AIM: To compare the intraocular pressure(IOP)measurements obtained with the rebound tonometry(RT), dynamic contour tonometry(DCT) and Goldmann applanation tonometry(GAT) in normal and glaucomatous eyes and investigate the effects of central corneal thickness(CCT) and corneal curvature(CC) on IOP measurements.METHODS: One hundred and twenty-four eyes of 124 subjects were enrolled in this cross-sectional study.Fifty-six of participants were healthy individuals and 68 of them were glaucomatous patients. IOP was measured on each subject always in the same order, ICare RT-Pascal DCT-GAT, after a minimum interval of 10 min between measurements. CCT and CC were measured using a rotating Scheimpflug camera before the IOP measurements in all subjects. One way repeated measures ANOVA, Pearson correlation coefficient and regression analysis, and Bland-Altman analysis was used for the statistical assessment.RESULTS: Mean IOP for all enrolled eyes was 16.00±3.80 mm Hg for GAT, 16.99 ±4.91 mm Hg for RT, and20.40 ±4.44 mm Hg for DCT. Mean differences between GAT and RT was-1.75±3.41 mm Hg in normal(P <0.001)and-0.37 ±3.00 mm Hg in glaucomatous eyes(P =0.563).Mean differences between GAT and DCT was-4.06 ±3.42 mm Hg in normal(P < 0.001) and-4.67 ±3.12 mm Hg in glaucomatous eyes(P <0.001). GAT and RT were significantly positive correlated with CCT in normal(r2=0.101, P =0.017 and r2=0.331, P <0.001, respectively) and glaucomatous eyes(r2=0.084, P =0.016 and r2=0.123,P =0.003, respectively). DCT was also significantly positive correlated with CCT in normal eyes( r2=0.179,P =0.001) but not in glaucomatous eyes(r2=0.029, P =0.165).All tonometers were unaffected by CC.CONCLUSION: IOP measurements by RT and DCT were significantly higher than GAT. DCT has highest IOP measurements among these tonometers. RT was most influenced tonometer from CCT although all tonometers were significantly positive correlated with CCT except DCT in glaucomatous eyes. CC did not influence IOP measurements. | Fatih Ozcura Nilgün Yildirim Afsun Sahin Ertugrul Colak | 2015 | International Journal of Ophthalmology(English edition)2015，8，2： | 3 |

| 9 | Retinal neurodegeneration in metabolic syndrome:a spectral optical coherence tomography study显示文摘AIM:To evaluate the effects of metabolic syndrome(Met S)on retinal neurodegeneration by optical coherence tomography(OCT).METHODS:Patients diagnosed as Met S were compared with the age and sex-matched healthy control group(CG).Waist circumference measurements,fasting serological biochemical tests,and systemic blood pressures of all participants were evaluated.The Met S group was divided into 3 subgroups according to the number of Met S components:hypertension,diabetes mellitus,dyslipidemia(low-,high-density lipoprotein,hypertriglyceridemia),and visceral obesity findings;3-component Met S3,4-component Met S4,and all-component Met S5.All patients underwent complete eye examination and spectral OCT retinal imaging.RESULTS:Totally 58 eyes of 58 patients were included in the Met S group and 63 eyes of 63 age and sex-matched healthy subjects were included in CG.Met S group was composed of 22 subjects in Met S3,21 subjects in Met S4,and 15 subjects in the Met S5 subgroup.Mean foveal thickness(Met S,218.7±23.1μm vs CG,228.8±21.9μm,P=0.015),mean inferior(Met S,283.4±17.0μm vs CG,288.7±38.4μm,P=0.002),superior(Met S,287.0±18.5μm vs CG 297.3±17.1μm,P=0.001),nasal(Met S 287.3±16.7μm vs CG 297.9±13.9μm,P=0.000)and temporal(274.5±17.6μm vs CG 285.6±13.6μm,P=0.000)thickness in the 3 mm Early Treatment of Diabetic Retinopathy Study(ETDRS)circle was significantly lower in the Met S group.There was no statistically significant difference in the mean inferior,superior,nasal,and temporal thickness of 6 mm ETDRS circle,total macular volume,peripapillary and macular retinal nerve fiber layer,macular ganglion cell layer with inner plexiform layer,and ganglion cell complex.No statistically significant difference was found in these values between the Met S3,Met S4,and the Met S5 groups.CONCLUSION:A significant reduction in central macular region thickness in Met S is detected and macular thickness is more susceptible to Met S induced neurodegeneration than peripapillary retinal nerve fiber layer. | Evrim Polat Ekrem Celik Mesut Togac Afsun Sahin | 2023 | International Journal of Ophthalmology(English edition)2023，16，2： | 0 |
