1. An automated slit lamp system for imaging an eye of a patient, the automated slit lamp system comprising:
a frame;
an illuminator mounted to the frame and emitting an illumination beam towards the eye of the patient, the illuminator being operable to illuminate the eye of the patient in a plurality of different illumination patterns;
a controller communicatively coupled to the illuminator, the controller having a processor and a memory having stored thereon instructions which when executed by the processor perform the steps of: controlling the illuminator to illuminate the eye of the patient with a sequence of illumination patterns comprising at least a first illumination pattern and a second illumination pattern being different from the first illumination pattern, the first and second illumination patterns being selected from a group comprising: diffuse illumination, direct focal illumination, tangential illumination, retroillumination, indirect illumination and sclerotic scatter illumination; and
a camera mounted to the frame and generating a plurality of images of the eye during both the first and second illumination patterns;
wherein the controller is communicatively coupled to the camera, the instructions further comprising: receiving the plurality of images from the camera; associating a first set of the received images to the first illumination pattern, associating a second set of the received images to the second illumination pattern, and generating time stamps indicating at least one of beginnings and ends of the first and second illumination patterns, said associating being performed based on said time stamps.
