Abstract
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.

A method of delivering
- a therapeutic substance to an eve of a patient the method comprising:
- introducing nanocapsules into a body of the patient such that at least a portion of the nanocapsules enter an eye of the patient, wherein the nanocapsules encapsulate a therapeutic substance and a colorant;
- and
- emitting pulsed laser radiation through a pupil of an eye of the patient;
- wherein the portion of the nanocapsules present in the eye is heated by the pulsed laser radiation, thereby causing at least a portion of the nanocapsules to release the therapeutic substance in the eye,
- wherein the pulsed laser radiation has a wavelength in a range of about 500 nanometers (nm) to about 600 nm.
