The eyes are complex sensory organs and are designed to optimize vision under conditions of varying light. There are a number of eye disorders that can influence vision. Eye disorders among the elderly are a major health problem. With advancing age, the normal function of eye tissues decreases and there is an increased incidence of ocular pathology. The most common causes of age related eye disorder and visual impairment in the elderly are cataracts and primary open angle glaucoma. Different imaging systems are available to visualize the different parts of the eye non-invasively with higher accuracy. This paper discusses the various techniques available namely, computed tomography, confocal laser scanning microscopy, magnetic resonance imaging, optical coherence tomography, ultrasound imaging, infrared thermography for the imaging of the different eye abnormalities.
