One of the unique features of OphthalmologyWeb is the extensive collection of professional videos. By clicking on the video tab, you are able to peruse a vast number of video presentations, which are searchable by subspecialty. Here is a summary of the most recent additions to the collection:
The Benefits of Daytona from Optos: This video is a concise overview of the Daytona ultra-widefield retinal imaging device from Optos. It is a compact, patient friendly, easy to use instrument that utilizes lasers to automatically capture a 200-degree view of the retina in under a second. The resulting scan is presented as a high-resolution digital optomap. The device also has multiple imaging modalities including color, red-free, autofluorescence, and angiography. Non-mydriatic images can be obtained through pupils as small as 2 mm. Built-in software enables the user to enhance and magnify the images. The Daytona improves the ability to detect lesions, and it is an excellent device for diagnosing, documenting, and managing retinal abnormalities.
Exam Technique for Standardized A-Scan with Quantel Medical Ultrasound: this video reviews the fundamentals of A-scan ultrasonogrphy including why and how to perform this test with the Aviso S (Quantel Medical). The use of diagnostic A-scan to complement findings from B-scan images is also reviewed with specific attention to the classification of A-scan structure and reflectivity. A-scan is a valuable tool that can provide detailed topographic and quantitative information about intraocular and orbital structures and pathology.
Performing A-Scan Biometry with Quantel Medical Ultrasound Systems: This video demonstrates the basics of A-scan biometry with attention to ultrasound physics, equipment features, how to obtain reliable scans, and criteria for good scans. IOL calculations and supplemental B-scans are also discussed. This is an excellent summary of A-scan ultrasonography for both novice and experienced users.
B-Scan Screening with Quantel Medical Ultrasound Systems: This “how to” video shows the proper method for performing B-scan ultrasound exams. Equipment set-up and patient positioning are reviewed, followed by a detailed step-by-step description of how to perform the exam and the 4 techniques for imaging the entire globe (transverse, longitudinal, oblique transverse, and axial).
M&S Techonlogies: Computerized Vision Testing: This short video provides information about the popular computerized vision testing products available from M&S technologies. All of the tests and algorithms are peer reviewed and certified by ANSI and ISO. Specific products highlighted are the All-in-One Smart System 20/20 USA and the Smart System USA PC-Plus. These Smart Systems have a tablet that functions as not only a controller for the system, but also serves as a near vision testing device with various apps including color screening, contrast sensitivity, Worth 4 dot, stereo vision, and reading acuity. Other features of the Smart System are a patented glare testing device and a sports vision performance module that tests eight aspects of visual performance. Additional special modules include a contrast sensitivity testing suite and a clinical trials suite.
Image Acquisition and Exam Technique for Ultrasound: This video details the basics of ultrasound biomicroscopy (UBM) with the Quantel Medical device. Topics covered include equipment set up, indications and features of UBM, exam techniques, and image acquisition. The Quantel systems are versatile and a number of the units can be used to obtain A-scan, B-scan, and UBM images. UBM scans require the use of the appropriate 25 MHz and 50 MHz probes to obtain axial, transverse, longitudinal, and oblique transverse scans. The use of UBM for cornea, angle, iris, ciliary body, IOL, and phakic IOL assessments and measurements is also demonstrated with representative images.
