Abstract: 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.

Abstract: The present invention relates to an eye examination apparatus comprising an illuminator adapted to project a light beam to illuminate the retina of an eye; an image sensor adapted to receive light reflected by the retina and to acquire images of the retina; scanning means adapted to perform optical scans of the retina moving the light beam projected on the retina along a scanning direction; separation means of the light beams adapted to separate the projected light from the light reflected by the retina and directed toward said image sensor; and a control unit to control the operation of said scanning apparatus. During the operation of said apparatus, in order to acquire each single image of a region of the retina to be framed, said image sensor integrates light reflected by the retina during at least two complete optical scans of said region of the retina by said scanning means.

Abstract: A scanning perimeter as disclosed herein comprises a first projection means projecting a first projection beam to uniformly illuminate a portion of a retina, said first projection beam passing through the pupil of the eye at a second separation region between a first crossing region, at which said illumination beam passes through the pupil, and a second crossing region of the pupil, at which light reflected by the retina passes through the pupil. A second projection means projects a second projection beam to project at least a fixation target on the retina, said second projection beam passing through the pupil at said first crossing region or said second crossing region. A third projection means projects a third projection beam to project at least a light stimulus on the retina, said third projection beam passing through the pupil at said first crossing region or said second crossing region.
