Researchers at University of Cagliari Have Reported New Data on Optical Coherence Tomography (Spectral-Domain Optical Coherence Tomography Study on Dynamic Changes of Human Tears After Instillation of Artificial Tears)
By a News Reporter-Staff News Editor at Health & Medicine Week -- Data detailed on Optical Coherence Tomography have been presented. According to news reporting out of Cagliari, Italy, by NewsRx editors, research stated, "To analyze in vivo the dynamic changes induced by different artificial tears (ATs) in the precorneal tear film (PCTF) and lower tear meniscus (LTM) by using spectral-domain (SD) anterior segment optical coherence tomography (OCT). We prospectively examined 42 normal human eyes by using SD-OCT imaging."
Our news journalists obtained a quote from the research from the University of Cagliari, "On the day before OCT imaging, all enrolled subjects were evaluated for abnormalities of ocular surface. All tear film images were obtained before and after instillation of three different types of ATs (mucomimetic, lipid-based, and saline) in five serial scans: immediately (within 30 seconds), at the first, fifth, 10th, and 20th minute. Subjects received a drop of 35 mu L in one randomly selected eye. All examinations were conducted in the same conditions of temperature, brightness, humidity, and time of day. Changes in the morphological pattern of both LTM and PCTF were associated with the type of artificial tear instilled on the ocular surface."
According to the news editors, the research concluded: "Similarly, the radius of curvature (rę), the height (h), and the depth (d) showed dynamic variations depending on treatment."
