Method and apparatus can be provided according to an exemplary embodiment of the present disclosure. For example, with at least one first section of an optical enclosure, it is possible to provide at least one first electro-magnetic radiation. In addition, with at least one second section provided within the enclosure, it is possible to cause, upon impact by the first radiation, a redirection of the first radiation to become at least one second radiation. Further, with at least one third section of the optical enclosure, it is possible to cause at least one second radiation to be provided to a tissue. For example, the redirection of the first radiation causes, at least approximately, a uniform optical illumination on of a surface of the tissue.

An adjustable illuminator for photodynamically diagnosing or treating a surface includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.

A method of macular disease treatment (500) may include introducing nanocapsules into a body of a patient (502). The nanocapsules may be introduced such that the nanocapsules circulate through at least a portion of a body of the patient. A therapeutic substance and a colorant may be encapsulated into the nanocapsules. After a portion of the nanocapsules enters choroidal neovessels of an eye of the patient, the method may include emitting a pulsed laser radiation through a pupil of the eye (504). Additionally, after a portion of the nanocapsules enters choroidal neovessels of an eye of the patient, the method may include heating the portion of the nanocapsules present in the eye (506) such that at least a portion of the nanocapsules transfer phase and release the therapeutic substance.
