Imaging apparatus and filters are provided for accurately imaging, assessing and measuring a patient's macular pigment. A multi-band filter is employed in combination with a color digital fundus camera to provide a method that operates with a single imaging exposure. The multiband filter has bandpass regions within spectral ranges of the red, green and blue detectors of the CCD array employed within the fundus camera, the bandpass regions being sufficiently sharply defined so as to avoid regions where the CCD detector responses spectrally overlap. This provides three discrete channels of grayscale data corresponding to the bandpass regions of the multiband filter, which can be used to calculate macular pigment topographically. Methods are also disclosed for calculating the optical density of the macular pigment and advantageously displaying the resulting data.

Steerable and flexibly curved probes are provided, primarily for surgical applications. A probe with flexible distal portion is inserted through an incision or cannula and the flexible distal portion may be selectively bent or steered using a guide wire. The guide wire is extended through the probe on a radially offset axis, and affixed at its distal end to the distal end of the flexible distal portion. The curvature of the nitinol wire is induced by extending or retracting the wire from the proximal end of the flexible distal portion while the distal end of the guide wire remains affixed to the distal end of the probe. The guide wire is activated by a finger-actuated mechanism. A further embodiment is provided in which the guide wire is fixed at both ends of the flexible distal portion of the probe and has a normally curved conformation, and assumes such conformation after insertion through a straight cannula. Other embodiments and applications are similarly disclosed.

Systems and methods for constructing a widefield image of the retina from a plurality of retinal images. In one aspect, the disclosure concerns constructing a widefield image of the retina from a plurality of retinal images, comprising a base image and a plurality of peripheral images. These techniques enable medical observations of retinal phenomena in patients, such retinal vein occlusion, artery occlusion, retinal detachments, intraocular inflammation, ocular tumors, and the like, that were difficult to detect and impossible to quantify under prior art approaches.

Methods and apparatus for taking autofluorescence images with a fundus camera capable of a field of view of at least 30 degrees and preferably 50 degrees or more using high quality thin film optical interference filters. In one embodiment, a filter set is disclosed for achieving this functionality. Using these methods and/or apparatus, a practitioner can (among other procedures, which are described) take high-quality autofluorescence images of the fundus using a CCD camera that does not have to be cooled, take such images without exciting damaging photochemical reactions in the retina, detect accumulation of fluorophores in the retina prior to the significant accumulation of fluorophores in the retinal pigment epithelium, and topographically localize and quantitate retinal abnormalities and retinal pigment epithelium abnormalities.
