    2. 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 ...

    4. 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.

    5. En-face Optical Coherence Tomography as a Novel Tool for Exploring the Ocular Surface: A Pilot Comparative Study to Conventional B-Scans and In Vivo Confocal Microscopy

      En-face Optical Coherence Tomography as a Novel Tool for Exploring the Ocular Surface: A Pilot Comparative Study to Conventional B-Scans and In Vivo Confocal Microscopy

      Purpose To explore the potential of spectral-domain optical coherence tomography (SD-OCT) using the en-face technology for the imaging of ocular surface diseases and to correlate the findings with in vivo confocal microscopy (IVCM) images. Patients and methods 113 eyes of 75 subjects with various ocular surface diseases were investigated with the RTVue ® anterior-segment en face OCT. En face OCT images were compared to B-scans OCT and IVCM images. Results: Patients with corneal dystrophies, corneal deposits, keratitis, pterygium, conjunctivochalasis, or ocular surface squamous neoplasia and patients who underwent lamellar corneal surgeries were included. En face OCT images showed ocular surface tissue ...

    8. Comparison of a MEMS-Based Handheld OCT Scanner With a Commercial Desktop OCT System for Retinal Evaluation

      Comparison of a MEMS-Based Handheld OCT Scanner With a Commercial Desktop OCT System for Retinal Evaluation

      Purpose: The goal of this study was to evaluate the ability of our handheld optical coherence tomography (OCT) scanner to image the posterior and anterior structures of the human eye, and especially the individual layers of the retina, and to compare its diagnostic performance with that of a fixed desktop commercial ophthalmic OCT system. Methods: We compared the clinical imaging results of our handheld OCT with a leading commercial desktop ophthalmic system (RTVue) used in specialist offices. Six patients exhibiting diabetes-related retinal pathology had both eyes imaged with each OCT system. Results: In both sets of images, the structural irregularities ...

      Artifacts in optical coherence tomography

      Optical coherence tomography (OCT) is now an integral part of management for numerous retinal diseases for diagnosis, treatment planning and follow up. OCT interpretation must involve the understanding of the associated artifacts. These artifacts can mislead physicians to wrong diagnosis or inappropriate management. This review article discusses the various types of artifacts in OCT scans obtained from various devices in various retinal diseases. This article would help to improve the understanding about the various artifacts and their clinical importance.

    11. Corneal Epithelial Remodeling Following Cataract Surgery: Three-Dimensional Investigation With Anterior-Segment Optical Coherence Tomography

      Corneal Epithelial Remodeling Following  Cataract Surgery: Three-Dimensional  Investigation With Anterior-Segment Optical  Coherence Tomography

      PURPOSE: To map corneal and epithelial layer thickness changes following cataract removal surgery employing a spectral-domain anterior-segment optical coherence tomography system. METHODS: Corneal and epithelial thickness three-dimensional profile distribution was clinically imaged preoperatively and up to 3 months postoperatively with anterior-segment optical coherence tomography in 116 consecutive cases. Descriptive statistics investigated central corneal thickness, minimum corneal thickness, and epithelial thickness at the central 2-mm area, the mean over the 6-mm area, and mid-peripherally at 5-mm ring. RESULTS: In comparison to preoperative, the center, mean, and mid-peripheral epithelial thickness at the first postoperative day increased by +2.84, +2.35, and ...

      Feature Of The Week 4/11/14: Virtual Reality Simulator for Vitreoretinal Surgery using Integrated OCT Data

      Its clear that OCT is playing increasingly important role in integrated surgical devices. There are numerous research and clinical papers that have been recently published and there are several innovative companies that have products in this area including Zeiss, Bioptigen, LenSx, Optimedica, and others. Its natural that virtual reality simulators would play a role in training surgeons to uses these tools. Recently researchers from King Khaled Eye Specialist Hospital and University of Illinois College of Engineering published preliminary results on this topic as shown below. Operative practice using surgical simulators has become a part of training in many surgical specialties ...
