The DEA is intended to do the exams related to the analysis and possible diagnosis of Dry Eye Disease(DED) through the connection of the device to you pc, and particularly.• Interferometry: records a video to the patient’s eye to analyze quantitatively and qualitatively lipid layer of the tear film, to compare it with the related grading scale and save the value;• Tear Meniscus Hight: The tear secretion of the lacrimal layer was assessed by measuring the height of the tear meniscus;• NIBUT: recording a video, it allows to evaluate the stability of the tear film between the break up time in a non-invasive way and to save the value;• Fluorescein BUT: records a video for the evaluation of the tear film’s stability, but it is done with instillation of the fluorescein in the patient’s eye(invasive) and without cone;• Meibography: takes a picture of meibomian glands using infrared light. The device can analyze automatically the loss area of the glands to compare it with the related grading scale;• Additional exams: checks for Bulbar Redness, Blepharitis, Demodex, pupillometry.All the exams that can be performed with the DEA are of fundamental importance for the ophthalmologist and the optometrist (within their respective professional skins) to study the tear film and for coaching the exams done with the classic instruments (Slit Lamp, Topography, Tonometry, etc.).
A mains electricity (AC-powered) multi-purpose optical device intended for: 1) infrared (IR) image capture of the meibomian glands for evaluation of structural abnormalities of the meibomian glands; 2) measurement of the tear film lipid layer using white light image/video capture interferometry; and 3) image capture of the external ocular anatomy. It includes patient head/chin supports, an IR source(s), appropriate cameras, controls and software intended to allow analysis of the images/video and interferometry; it may include an eyelid everter to assist imaging of the meibomian glands.
