Ophthalmic machine for acquiring fluorescence images of the retina and related method of use
An ophthalmic machine is provided for obtaining and diagnosing fluorescence images of the retina. An excitation light having first wavelengths (e.g., between 430 nm and 490 nm) is scanned onto the retina. Light emitted by the retina, when illuminated thereby, is filtered to block light of the first wavelengths and to pass light of second (higher) wavelengths. A second filter selects a component of the passed light having second (e.g., green) wavelengths, and a third filter selects a component of the passed light having third (e.g., red) wavelengths. First and second detection means receive light transmitted by the first and second filters, respectively, and provide detection signals indicative thereof. The detection signals are processed to provide one or more images of the retina, said images of the retina comprising at least a color fluorescence image of the retina.

The present invention relates to an apparatus for inspecting the fundus of the eye, comprising: —lighting means configured to project a light beam for illuminating the retina of one eye; and —an optical path comprising one or more lenses configured to optically conjugate the retina with a receiving surface of acquisition means configured to acquire one or more images of the retina; and —a beam splitter device configured to divert a part of the light, which is reflected by the retina and directed towards said acquisition means, towards first photosensitive elements; and —a control unit operatively associated with said first photosensitive elements, said acquisition means and said lighting means, said control unit deactivating said lighting means when the light energy received from said first photosensitive elements overcomes a predefined threshold value; and —first LED devices configured to project light targets onto the retina, which the patient must stare to keep the eye still during the examination. The mentioned first photosensitive elements and first LED devices are arranged together in a single integrated optical unit configured to receive light from the retina and to project light onto the retina through said beam splitter device.

The present invention relates to a lighting device comprising a light concentrator device operatively associated with a light source comprising a plurality of LED devices. The light concentrator device is composed of a solid transparent body comprising: a first surface (51), at which a light input section (5) is defined to receive the light radiation emitted by the light source; and—a second surface (61), at which a light output section (6) is defined to transmit a light beam having a ring shape; and a plurality of protrusions (7) that protrude from said first surface, at said light input section, said protrusions acting as collimation lenses of the light radiation coming from said light source; and—a plurality of reflection surfaces (8, 9) of the light radiation received from said light input section, said protrusions and said reflection surfaces being mutually positioned so as to convey the light radiation coming from said light source along a predefined path, which extends internally to said transparent body, between said light input section and said light output section.
