    4. Device and method for measuring an optical break-through in a tissue

      Device and method for measuring an optical break-through in a tissue

      ] The invention relates to a device for measuring an optical penetration that is triggered in a tissue underneath the tissue surface by means of therapeutic laser radiation which a laser-surgical device concentrates in a treatment focus located in said tissue. The inventive device is provided with a detection beam path comprising a lens system which couples radiation emanating from the tissue underneath the tissue surface into the detection beam path. A detector device generating a detection signal which indicates the spatial dimension and/or position of the optical penetration in the issue is arranged downstream of the detection beam path.

      Surgical microscope system and method

      A microscopy system and method allow observing a fluorescent substance accumulated in a tissue. The tissue can be observed at a same time both with visible light and with fluorescent light. It is possible to observe a series of previously recorded fluorescent light images in superposition with the visible light images. An end of the series of images may be automatically determined. A thermal protective filter may be inserted into a beam path of an illuminating system at such automatically determined end of the series. Further, the fluorescent light image may be analyzed for identifying a coherent fluorescent portion thereof ...

    7. Methods to reduce variance in OCT analysis of the macula

      Methods to reduce variance in OCT analysis of the macula

      Methods for analyzing optical coherence tomography (OCT) images of the macula to reduce variance and improve disease diagnosis are presented. One embodiment of the invention is directed towards selecting analysis locations and data segmentation techniques to take advantage of structural homogeneities. Another embodiment is directed towards reducing the variance in a collection of normative data by transforming the individual members of the database to correspond to a Standard Macula. Variations in foveal size are corrected by radial transformation. Variations in layer thickness are corrected by axial shifting. Diagnosis is performed by comparing OCT images from a patient to the improved ...

    9. Evaluation of dacryocystorhinostomy using optical coherence tomography and rebamipide ophthalmic suspension

      Evaluation of dacryocystorhinostomy using optical coherence tomography and rebamipide ophthalmic suspension

      Purpose: To evaluate the surgical outcome of dacryocystorhinostomy (DCR) by measuring the tear meniscus, using optical coherence tomography and rebamipide ophthalmic suspension. Methods: Patients with nasolacrimal obstruction and chronic dacryocystitis who were scheduled for an endonasal DCR underwent tear meniscus examinations before and 2 months after surgery. Vertical scans of the inferior menisci were performed before and at 1, 3, 5, 7, and 10 minutes after the instillation of rebamipide ophthalmic suspension. The tear menisci areas were measured with imaging software. Ten young adults without epiphora formed the control group. Results: Anatomical success was achieved on 22 sides of 21 ...

      Evaluation of Pachymetric Measurements with Scheimpflug Photography-Based System and Optical Coherence Tomography Pachymetry at Different Stages of Keratoconus

      The aim of this study was to compare the central and peripheral pachymetric measurements determined with Sirius system and Visante OCT and evaluate the agreement between them at different stages of keratoconus. Measurements were not significantly different in all patients and subgroups and showed high correlation for the corneal thicknesses of the entire cornea in different stages of keratoconus.

    12. Two-dimensional confocal imaging using OCT light source and scan optics

      Two-dimensional confocal imaging using OCT light source and scan optics

      Various approaches are disclosed for simultaneously generating optical coherence tomography (OCT) and confocal scanning laser images by spatially separating the signal normally used for OCT imaging with selective reflecting or beam directing devices. In one preferred embodiment, the invention includes a mirror having a central transmission region, such that the radially outer region of the returning signal beam is reflected and used for generating a confocal image while the central part of the signal beam is transmitted and used to generate an OCT image. In other embodiments, the signals may be spatially separated in other ways, such as with an ...

    13. Inner and outer central retinal findings after surgery for rhegmatogenous retinal detachment using different spectral-domain optical coherence tomography devices

      Inner and outer central retinal findings after surgery for rhegmatogenous retinal detachment using different spectral-domain optical coherence tomography devices

      Purpose The aim of the study was to analyse macular changes after rhegmatogenous retinal detachment (RRD) repair using spectral-domain optical coherence tomography (SD-OCT). Methods Forty eyes with macula-on and 27 eyes with macula-off RRD underwent scleral buckling or vitrectomy and were postoperatively imaged using 2 SD-OCT devices (Cirrus® HD-OCT, RTVue-100®). Measurement of total and inner macular thickness consisting of ganglion cell layer + inner plexiform layer (GCL-IPL) using Cirrus or retinal nerve fibre layer + ganglion cell layer + inner plexiform layer (RNFL-GCL-IPL) using RTVue was performed. Results of inner macular thickness were compared with image results of 40 healthy controls. Qualitative analysis ...
