5 maj 2021 · In summary, in this study, we demonstrated a simple and compact PAM with a large-size transparent ultrasound transducer, which overcomes the trade-offs between imaging speed and FOV in current PAMs and achieves fast imaging over a centimeter-scale range with a lateral resolution of 17.5 µm.
The power for imaging systems with continuous viewing is measured at the cornea for human retinal imaging applications, ranging from 14 microwatts/cm 2 to 450 microwatts/cm 2 on the retina for visible wavelengths, and up to 30 mW/cm 2 in the near infrared. The light used for imaging the cornea and other anterior segment structures is typically ...
15 cze 2020 · Visual field (VF) testing, although sometimes described as “torturous” by our patients, can be gratifying (and important) to interpret as an ophthalmologist, especially when done systematically. This article provides quick pearls and a framework by which you can conquer interpretation of VFs and points you in the direction of relevant ...
Light Amplification by Stimulated Emission of Radiation (LASER) therapy utilizes a highly specific and concentrated beam of light that can be used to alter tissues in the medical treatment of disease (i.e., medical grade lasers).
28 kwi 2021 · The reflection-mode PAM not only retains the advantage of high scanning speed for optical scanning, but also offers an imaging field-of-view (FOV) up to 20 × 20 mm 2, which is the largest FOV available in laser-scanning models so far.
23 kwi 2024 · Visual field (VF) testing dates back to fifth century B.C. It plays a pivotal role in the diagnosis, management, and prognosis of retinal and neurological diseases. This review summarizes each of the different VF tests and perimetric methods, including the advantages and disadvantages and adherence to the desired standard diagnostic criteria.
After the eye is well-docked, anterior segment optical coherence tomography (OCT) shows real-time images of the cornea, iris, and lens. Anterior and posterior lens capsules can also be clearly imaged. After reviewing the images and checking the treatment parameters, the surgeon starts the laser.
