A system and method are presented for use in delivering electromagnetic radiation to a limbal area of an eye, for example for treatment of glaucoma. The system includes an illumination unit, a beam shaping device and a control unit. The illumination unit includes a first source of electromagnetic radiation configured and operable for producing a beam of electromagnetic radiation having first optical properties to be delivered to the limbal area of a patient's eye to interact therewith and produce a desired effect, and a second source of electromagnetic radiation configured and operable for producing a beam of electromagnetic radiation having second optical properties. The beam shaping device when accommodated in an optical path of said first and second beams defines one or more regions along a path substantially aligned with a limbus of the patient's eye. The control unit is configured and operable for operating the illumination unit in first and second illumination modes, such that in the first illumination mode the second beam propagates towards said beam shaping device and upon identifying that the second beam illuminates the limbus, the second illumination mode is activated in which the first beam is directed via said beam shaping device to pass through said one or more regions along said path to thereby interact with the limbus.
