Cím:Evaluation of normal corneas using the scanning-slit topography/pachymetry system / Módis L., Langenbucher A., Seitz B.
Dátum:2004
ISSN:0277-3740
Megjegyzések:Purpose: To obtain anterior and posterior corneal shape, curvature, and thickness of normal human corneas. To provide a semiquantitative analysis of normal topography patterns of the anterior and posterior corneal surfaces. Methods: Eighty-eight healthy corneas of 44 normal subjects were analyzed using the scanning-slit topography/pachymetry system. Anterior and posterior elevation and mean power (central and steepest spherical and cylindrical) values and pachymetry data were determined. Right eye values were submitted for primary analysis; however, a comparison between right and left eyes was made in addition to test the possible reliability of the system. Results: There was no significant difference between right and left corneas in 28 evaluated parameters, except for anterior central cylindrical (P = 0.005) and steepest cylindrical (P = 0.017) mean power. The anterior central spherical mean power correlated inversely with the posterior central spherical mean power (r = -0.27, P = 0.04), and the anterior steepest spherical mean power value showed inverse correlation with the mean posterior steepest spherical value (r = -0.44, P = 0.001). The mean central thickness of the cornea was 593.7 ± 54.19 um at the center and was 578 ± 50.53 um at the thinnest point, which was localized in 41% (n = 18) of the cases in the inferotemporal quadrant. An oval-shaped pattern was the most characteristic feature of the anterior and posterior elevation, mean power, and pachymetry maps. Conclusion: Orbscan scanning-slit topography seems to be a reliable technique for the evaluation of normal corneas not only for anterior shape and curvature but also for a real pachymetry gradient recording.

Cím:Keratometry evaluations with the pentacam high resolution in comparison with the automated keratometry and conventional corneal topography / László Módis, Eszter Szalai, Bence Kolozsvári, Gábor Németh, Attila Vajas, András Berta
Dátum:2012
ISSN:0277-3740
Megjegyzések:To determine the reliability and repeatability of keratometry (K) measurements obtained with the Pentacam high resolution (HR), automated keratometry, and corneal topography systems. METHODS: : The right eyes of 46 healthy subjects were examined prospectively. Keratometry measurements in the flat (Kf) and steep (Ks) meridians were taken by 2 independent investigators with the Pentacam HR (Oculus, Wetzlar, Germany) followed by automated keratorefractometry (KR-8100; Topcon, Tokyo, Japan), and corneal topography (TMS-4; Tomey, Erlangen, Germany). RESULTS: : The mean K readings of the Pentacam HR, automated keratometry, and corneal topography were 43.40/43.34 diopter (D), 43.99/43.98 D, and 43.80/43.83 D, respectively. The difference between the values was statistically significant (P < 0.0001, repeated measures analysis of variance). Strong significant correlation was observed between the Pentacam HR and keratometry (Kf: r = 0.952/0.954; Ks: r = 0.845, Spearman rank test), and Pentacam HR and corneal topography (Kf: r = 0.933/0.930; Ks: r = 0.838/0.829) (P < 0.0001). No significant difference was presented between the 2 investigators for any of the instruments (P = 0.215-0.983). Moreover, high correlation was found between the K readings of the observers (interoperator intraclass correlation coefficients ranged from 0.95 to 0.99). CONCLUSIONS: : The Pentacam HR provided reliable K measurements in clinical practice in comparison with an automated keratometer and a corneal topographer. Based on the results, for patient follow-up, one keratometry device is recommended.

Cím:Reliability of the Corneal Thickness Measurements with the Pentacam HR Imaging System and Ultrasound Pachymetry / Módis L. Jr., Szalai E., Németh G., Berta A.
Dátum:2011
ISSN:0277-3740
Megjegyzések:PURPOSE: To obtain the central corneal thickness (CCT) of healthy eyes using the rotating Scheimpflug imaging system and compare these results with conventional ultrasound pachymetry values. Interoperator reliability and repeatability of the different techniques were also determined. METHODS: CCT was measured on the right eye of 46 healthy subjects with the Pentacam HR (Pentacam High Resolution; Oculus, Wetzlar, Germany) and contact ultrasound pachymetry (AL-2000; Tomey, Tennenlohe, Germany) by 2 independent investigators. RESULTS: Both observers obtained significantly higher CCT readings with the Pentacam HR imaging system (572 ± 33 and 575 ± 31 m) than with the ultrasound device (546 ± 27 and 548 ± 28 m) (P < 0.0001, paired Student t test). Strong and significant correlation was found between the 2 pachymetry techniques regardless of the investigator (r = 0.845 and 0.831, Spearman correlation coefficient) (P < 0.0001). For the Pentacam HR values, statistically significant difference was detected between the observers (P = 0.033). For both pachymetry methods, the degree of agreement between the investigators was reflected by the high interoperator intraclass correlation coefficient value (ICC = 0.96). No significant difference was disclosed between the 3 consecutive readings of either instrument (P > 0.05, analysis of variance). CONCLUSIONS: Significant difference in CCT values between the high-resolution Pentacam imaging system and the ultrasound pachymeter suggests that the 2 techniques cannot be used interchangeably in clinical practice.

Cím:Scanning-slit and specular microscopic pachymetry in comparison with ultrasonic determination of corneal thickness / Módis L., Langenbucher, A., Seitz, B.
Dátum:2001
Megjegyzések:To determine the central corneal thickness values in healthy eyes with the recently developed Orbscan scanning-slit system, contact and noncontact specular microscopic pachymetry and compare the results to conventional ultrasonic pachymetry. METHODS: In the following sequence, Orbscan, Topcon SP-2000P noncontact specular microscope, AL-1000 ultrasound, and Tomey contact specular microscope were used to record thickness values. Thirty-four healthy right corneas of 34 healthy subjects were investigated. RESULTS: Orbscan pachymetry correlated significantly with ultrasound (r = 0.64, p < 0.001), contact (r = 0.45, p < 0.001), and noncontact specular microscopy (r = 0.72, p < 0.001). Likewise, the Topcon SP-2000P noncontact specular microscopy pachymetry disclosed similar statistical results compared with ultrasound (r = 0.88, p < 0.001), and contact specular microscopy pachymetry (r = 0.76, p < 0.001). The mean central corneal thickness results were significantly higher ( p < or = 0.01) than ultrasonic values (580 +/- 43 microm) using the contact specular microscope (640 +/- 43 microm) or Orbscan system (602 +/- 59 microm) but were significantly lower ( p < 0.001) using the noncontact specular microscope (547 +/- 49 microm). CONCLUSIONS: The results indicate that the devices tested cannot be simply used interchangeably. For long-term patient follow-up, one specific instrument is recommended. Recently developed pachymetry machines are especially helpful when additional corneal data such as thickness profile, elevation maps, anterior chamber depth, and endothelial morphology are required.

Cím:Evaluation of Tear Osmolarity in Non-Sjögren and Sjögren Syndrome Dry Eye Patients With the TearLab System / Eszter Szalai, András Berta, Zoltán Szekanecz, Gabriella Szűcs, László Módis
Dátum:2012
ISSN:0277-3740
Megjegyzések:Purpose: To evaluate tear osmolarity with the recently introduced TearLab system (TearLab Corporation, San Diego, CA) in patients with non-Sjogren syndrome dry eye (NSSDE) and Sjogren syndrome dry eye (SSDE), and in healthy subjects, and to compare the results with those from classical dry eye tests.Methods: Thirty-nine eyes of 21 patients with NSSDE, 39 eyes of 20 patients with SSDE, and 44 eyes of 22 healthy individuals were included in the study. Tear osmolarity was measured with the TearLab system, lid-parallel conjunctival folds score was examined with the slit lamp, and then the classical diagnostic tests such as Schirmer I test, tear film break-up time, and corneal staining were carried out, followed by the examination of meibomian glands and corneal transparency.Results: Mean tear osmolarity was 296.77 +/- 16.48 mOsm/L in NSSDE (15% abnormal), 303.36 +/- 17.22 mOsm/L in SSDE (23% abnormal), and 303.52 +/- 12.92 mOsm/L in the control group (16% abnormal; P = 0.018, Kruskal-Wallis). Schirmer test, corneal staining, tear film break-up time, and meibomian gland status were significantly different in the 2 patient groups when compared with those in the control group (P < 0.0001). In the control and SSDE groups, no significant correlation was disclosed between tear osmolarity and any of the dry eye tests performed.Conclusions: Tear hyperosmolarity is considered a key factor that leads to dry eye symptoms and to the progression of clinical signs. Osmolarity measurements with the TearLab system disclosed no ability to distinguish between healthy individuals and patients with dry eye. This suggests that the TearLab device should not be used alone but in combination with classical dry eye tests.

Cím:Evaluation of the Corneal Endothelium Using Noncontact and Contact Specular Microscopy / Szalai Eszter, Németh Gábor, Berta András, Jr. Módis László
Dátum:2011
ISSN:0277-3740
Megjegyzések:To determine the difference between the endothelial cell density (ECD) and the morphologic measurements assessed with a recently developed noncontact specular microscope compared with a contact endothelial microscope. The agreement between the 2 independent operators was also investigated. Methods: The central corneal endothelium was examined in the right eyes of 41 healthy individuals using automated image analysis programs without correction for a noncontact specular microscope and a contact specular microscope (EM-3000, EM-1000; Tomey, Tennenlohe, Germany). The evaluated parameters such as ECD, average cell area (AVG), and coefficient of variation of the cell area were determined by 2 operators. Conversion factors were also considered to adjust the ECD values. Results: ECD measurements obtained with the noncontact instrument (2734 +/- 287 cells per square millimeter, first operator; 2726 +/- 282 cells per square millimeter, second operator) were significantly higher (P < 0.0001) in comparison with the contact microscope (2283 +/- 206 cells per square millimeter, first operator; 2274 +/- 242 cells per square millimeter, second operator) by both investigators. The contact specular microscope significantly over-estimated (P < 0.0001) AVG and coefficient of variation of the cell area values. Statistically significant correlation (P < 0.0001) was detected in ECD (r = 0.77, first operator) and AVG measurements (r = 0.72, first operator) between the 2 endothelial microscopes. Higher degree of agreement between operators was given when using the noncontact specular microscope compared with the contact instrument. Conclusions: The significant differences and the poor agreement between the automated software options disclosed that the 2 instruments cannot be used interchangeably.
