    2. Detecting signs of retinal leakage in exudative AMD using Cirrus OCT versus SL SCAN-1, a novel integrated FD-OCT into a common slit lamp

      Detecting signs of retinal leakage in exudative AMD using Cirrus OCT versus SL SCAN-1, a novel integrated FD-OCT into a common slit lamp

      Purpose The purpose is to evaluate the interdevice and interobserver agreements between the SL SCAN-1 (a FD-OCT integrated into a common slit lamp) and a standard stand-alone FD-OCT device (the Cirrus ) with regard to the presence or absence of signs of leakage in the retina in patients with exudative AMD and treated with anti- VEGF . Methods Fifty-six patients, known to have exudative AMD and under treatment with anti- VEGF agents, were included. During a regular follow-up, OCT scans were made with the Cirrus (macular-cube pattern) and the SL SCAN-1 (radial-scan pattern). All scans were graded by two medical retina specialists ...

    4. Intraoperative OCT improves ophthalmic surgery

      Intraoperative OCT improves ophthalmic surgery

      The most popular examination method in ophthalmology today is optical coherence tomography (OCT ). Traditionally, OCT examinations have been performed pre- and post-operatively in vitreo-retinal surgery. While this application of the technology has enabled outcomes to be measured and results to be documented, surgeons have not had the ability to incorporate the results to improve surgical treatments. But with considerable advances to OCT—including high-definition OCT (HD OCT), 3D visualization , and adaptive optics —the integration of these methods into the surgical microscope is logical. The technology is now helping ophthalmologists carry out delicate eye surgeries. In today's integrated microscopy systems ...

      Method For Detecting Corneal Astigmatism Using Optical Coherence Tomography

      The invention relates to a method for detecting refractive errors in the eye, said errors being attributable to a suboptimal surface shape of the front surface and/or rear surface of the cornea of an eye. In the method according to the invention for determining refractive errors in the eye, an OCT volume scan and/or one or more OCT line scans of the front eye section are carried out; using the measured values, the front and rear surface of the cornea are detected by means of an edge detection process; the topography of the front and rear surface of ...

      Anterior and Posterior Ocular Biometry in Healthy Chinese Subjects: Data Based on AS-OCT and SS-OCT

      Background To measure the anterior and posterior ocular biometric characteristics concurrently and to determine the relationship between the iris and choroid in healthy Chinese subjects. Methods A total of 148 subjects (270 eyes) were enrolled in this cross-section study. The anterior and posterior ocular biometric characteristics were measured simultaneously by anterior segment optical coherence tomography (AS-OCT) and swept-source optical coherence tomography (SS-OCT). Results Compared with male eyes, female eyes had narrower anterior biometric parameters that presented with smaller anterior segment parameters [including anterior chamber depth (ACD), width (ACW), area (ACA), and volume (ACV); (all p<0.001)], narrower anterior chamber ...

    9. Refractive Error and Ocular Parameters: Comparison of Two SD-OCT Systems

      Refractive Error and Ocular Parameters: Comparison of Two SD-OCT Systems

      Purpose: Spectral domain optical coherence tomography (OCT) was used to examine the influence of refractive error (RE) on foveal retinal and choroidal thicknesses and scleral canal width (SCW). The performance of the Cirrus and Bioptigen spectral domain OCT instruments was compared in the same eyes. Methods: Both eyes of 40 healthy human subjects, aged 22 to 38 years, were dilated and imaged, with the Cirrus OCT, using 6-mm five-line rasters collapsed into one line, one centered on the fovea and one bisecting the optic nerve head. Seventy-two of the same eyes were imaged with the Bioptigen OCT, using 6- by ...

    10. Reproducibility of Spectral-Domain Optical Coherence Tomography RNFL Map for Glaucomatous and Fellow Normal Eyes in Unilateral Glaucoma

      Reproducibility of Spectral-Domain Optical Coherence Tomography RNFL Map for Glaucomatous and Fellow Normal Eyes in Unilateral Glaucoma

      Purpose: To compare the reproducibility of the optical coherence tomography (OCT) retinal nerve fiber layer (RNFL) thickness map between glaucomatous and fellow normal eyes of unilateral glaucoma patients. Methods: In this prospective case-control study, Cirrus HD-OCT was performed for 79 unilateral glaucoma patients 3 times on the first visit and on 3 subsequent visits within a 2-month period. Test-retest standard deviation (TRT-SD) and tolerance limit based on the 1.645×√2×TRT-SD formula were derived for RNFL thicknesses at the respective superpixels of the RNFL thickness map. Results: The TRT-SDs and tolerance limits of the glaucomatous eyes (TRT-SD: 2.75 ...

    11. The relationship between structure and function as measured by OCT and Octopus perimetry

      The relationship between structure and function as measured by OCT and Octopus perimetry

      Background/aims To determine the structure–function relationship between equivalent visual field areas obtained with the Octopus perimeter (OP), and the peripapillary retinal nerve fibre layer (RNFL) thickness measured with spectral-domain optical coherence tomography (OCT) in healthy individuals and patients with glaucomatous optic neuropathy. Methods Eighty-eight normal subjects and 150 patients with open-angle glaucoma were prospectively recruited. Eligible participants for the glaucoma group were required to have elevated intraocular pressure and glaucomatous optic nerve head morphology. All participants underwent reliable automated perimetry with OP, and optic nerve head imaging with the Cirrus OCT. Principal component analysis of the mean threshold ...

      Macular thickness assessed with spectral domain OCT in a population-based study of children: normative data, repeatability and reproducibility and comparison with time domain OCT

      Purpose To collect data on macular thickness assessed with Cirrus OCT in healthy children in a population-based study, to examine the repeatability and reproducibility, and to compare the values with Stratus OCT. Methods Fifty-eight 6- to 15-year-old children, born at term, were examined. Best-corrected visual acuity and refraction were assessed. One examiner performed three OCT assessments, and the repeatability was calculated. Thereafter, a second examiner repeated the examinations to calculate the reproducibility. One eye was randomized to be included in the normal material. Finally, the second examiner assessed the macular thickness with the Stratus OCT. Results The mean value (±SD ...
