This book was released on 2024-02-10 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: While eye care providers are thoroughly familiar with the use of optical coherence tomography (OCT) in the diagnosis and management of glaucoma and retinal diseases, many are not as familiar with its myriad uses for the diagnosis of corneal and anterior segment conditions. Anterior segment OCT (AS-OCT) can help to differentiate between various corneal pathologies, show the anatomy of the angles, obtain information about the lens-capsule complex, and guide contact lens fitting, among many other clinical uses. Clinical Atlas of Anterior Segment OCT expertly guides clinicians through all aspects of AS-OCT with hundreds of high-quality OCT images that highlight the utility of AS-OCT in diagnosing and managing a wide spectrum of anterior segment diseases. Covers the entire normal anatomy of the anterior segment and pathology of the conjunctiva, corneal epithelium, stroma and endothelium, lens, iris, anatomic angle, and clinical settings such as trauma, infection, inflammation, and contact lens fitting. Includes information on using AS-OCT in clinical and surgical settings (intraoperative AS-OCT). Provides rich visual guidance with over 500+ high-quality figures (anterior segment OCT imaging and clinical photos) comparing normal anatomy and a wide range of pathology, including both common and rare disorders and how to differentiate frequently confused conditions. Provides a well-rounded perspective of AS-OCT, including how to use, understand, and capture images. Links high-quality slit lamp images to the corresponding AS-OCT image with clear labels to show the pathology side by side. Features clinical pearls in each chapter to relate key AS-OCT and clinical findings to everyday practice.

Download or read book Extending the Reach of Anterior Segment Ophthalmic Imaging written by Shantanu Sanjay Sinha and published by . This book was released on 2016 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eye exams via a slit lamp are critical in screening for conditions such as cataracts, corneal opacities and pterygia early on to avert vision loss. The slit lamp, however, is a purely qualitative optical device that is bulky, expensive, can cause eye discomfort due to light sensitivity. It also requires a trained physician to operate, making it unsuitable for large-scale screening in resource-constrained settings. In this thesis, we propose a spectrum of portable anterior segment imaging solutions that can be operated by minimally trained health workers. On one end, we present a smartphone attachment with minimal optics and no electronic components beyond what is present in the smartphone itself to examine and image the anterior segment of the eye. This cost-effective, easily scalable solution would help extend the reach of anterior segment examination to extremely resource constrained settings, such as mass-screening camps, mobile ophthalmology clinics, war zones etc. On the other end, we propose purely solid-state instrumentation that employs programmable illumination and light steering optics to simulate the motion of a slit on the eye, thereby exhibiting functionality similar to that of a slit lamp with no moving parts. Finally, we discuss potential deployment strategies for two implementations of this technology in the specific cases of two contrasting healthcare systems in India.
