      Feature Of The Week 9/21/14: National University of Singapore Investigates OCT as a Tool for Characterization of Complex Biological Surfaces Including Morphology of Crab Shells

      The advent of scanning electron microscopy has facilitated our understanding of the In recent years, there has been a growing interest in the study of natural biological surfaces in the search for novel solutions in surface engineering design from nature. Most methods for surface imaging of natural biological samples are however, sacrificial and require that samples be sectioned and prepared for characterization. One example is the use of the scanning electron microscope (SEM) to obtain detailed images of microtopography, where a section of the specimen is cut and sputter coated with electrically conductive material like gold or platinum for scanning ...

    3. Repeatability of peripapillary retinal nerve fiber layer and inner retinal thickness among 2 spectral domain optical coherence tomography devices

      Repeatability of peripapillary retinal nerve fiber layer and inner retinal thickness among 2 spectral domain optical coherence tomography devices

      PURPOSE. To compare measurement of macular inner retina and peripapillary retinal nerve fiber layer (pRNFL) thickness using 2 spectral-domain optical coherence tomography (OCT) devices in glaucoma patients, patients with ocular hypertension, idiopathic and atypical Parkinson's disease and healthy controls. METHODS. One-hundred seventy-one eyes of 146 participants underwent successful pRNFL and macular scanning and automated measurement of ganglion cell layer + inner plexiform layer (GCL-IPL) using Cirrus® HD-OCT or retinal nerve fiber layer + ganglion cell layer + inner plexiform layer (RNFL-GCL-IPL) using RTVue-100®. Macular RNFL was added to the GCL-IPL thickness measured by Cirrus and was compared to the RNFL-GCL-IPL thickness of ...

    4. Evaluation of the Macular Choroidal Thickness Using Spectral Optical Coherence Tomography in Pseudoexfoliation Glaucoma

      Evaluation of the Macular Choroidal Thickness Using Spectral Optical Coherence Tomography in Pseudoexfoliation Glaucoma

      Purpose: To evaluate the choroidal thickness (CT) in pseudoexfoliative (PEX) glaucoma and age-matched healthy subjects using spectral optical coherence tomography (SD-OCT). Patients and Methods: In this prospective study, 32 eyes of 32 PEX glaucoma patients and 30 eyes of 30 age-matched healthy subjects were enrolled. The CT is measured perpendicularly (from the outer edge of the hyperreflective retinal pigment epithelium to the inner sclera) at the fovea, and 1.5 mm temporal, 3.0 mm temporal, 1.5 mm nasal, and 3.0 mm nasal to the fovea using SD-OCT (RTVue-100). Results: The groups were similar regarding the mean age ...

      MACULAR AND PERIPAPILLARY SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY CHANGES IN SICKLE CELL RETINOPATHY

      Purpose: To assess peripapillary retinal nerve fiber layer, macular ganglion cell complex, and total macular thicknesses using spectral domain optical coherence tomography on sickle cell disease patients with and without sickle retinopathy. Method: Nineteen eyes of 11 patients with hemoglobin sickle cell disease, 65 eyes of 36 patients with hemoglobin SS disease, and 48 eyes of 24 healthy subjects underwent spectral domain optical coherence tomography scanning (RTVue). Eyes of patients with sickle cell disease were classified into 3 groups according to posterior segment changes: no retinopathy (n = 64), nonproliferative retinopathy (n = 12), and proliferative retinopathy (n = 8). Results: The central ...

    6. Influence of a New Software Version of the RTVue-100 Optical Coherence Tomograph on Ganglion Cell Complex Segmentation in Various Forms of Age-related Macular Degeneration

      Influence of a New Software Version of the RTVue-100 Optical Coherence Tomograph on Ganglion Cell Complex Segmentation in Various Forms of Age-related Macular Degeneration

      Purpose: Previously, we have shown that age-related macular degeneration (AMD) influences glaucoma classification with the ganglion cell complex (GCC) parameters of the RTVue-100 optical coherence tomograph (RTVue-OCT) in nonglaucomatous eyes. Now, we reevaluated the influence of AMD on GCC image segmentation and classification for glaucoma on the same eyes, using a new version of the software. Methods: GCC images of nonglaucomatous eyes [30 healthy, 19 with early/intermediate AMD, 16 with subfoveal choroidal neovascularization (CNV), and 19 after intravitreal antiangiogenic treatment of CNV, CNV-anti-VEGF] were reanalyzed with software versions 6.3 (the currently available version) and 6.12 (a version ...

    7. 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 ...

    9. Anterior Segment Optical Coherence Tomography Guided Nd:YAG Laser Iridocystotomy in Post Traumatic Iris Cyst

      Anterior Segment Optical Coherence Tomography  Guided Nd:YAG Laser Iridocystotomy in  Post Traumatic Iris Cyst

      A 30 year old female presented with a large post traumatic iris cyst obstructing the visual axis, with a corneal scar inferiorly. Anterior segment optical coherence tomography (AS-OCT) was done to identify the areas of corneal attachment and locate the thinnest area of the cyst. Nd:YAG laser iridocystotomy performed subsequently resulted in immediate deflation of the cyst, excellent restoration of visual acuity and no recurrence till 6 months of follow up. AS-OCT guided laser cystotomy has not been reported previously, to the best of our knowledge.
