    How to Write Your Thesis

    Getting Started At the very onset, we want to mention that we are no experts writing thesis or papers. But as somebody has correctly mentioned that in our discipline it is time and more time that makes you wise. (hey sorry we don’t have a reference for this). It’s a humble effort on our part to share our experiences with our fellow colleagues, with the hope that it may be helpful to some of them. As the modern lexicon goes Publish or Perish. Unfortunately, it is true. Someday or the other we must write papers, maybe for thesis or for conferences and for somebody just to build up his CV. So we really have to start someday. The toughest part is to begin it. We can really break up it into number of small steps and will be discussing them as we go along.

    Clinical Applications of Multicolor Imaging

    Multicolor imaging (MCI) is a non-invasive retinal imaging modality available in the Spectralis platform (Heidelberg Engineering, Heidelberg, Germany). It simultaneously acquires three reflectance images of the retina using three individual lasers of different wavelengths: blue (488 nm), green (515 nm), and infrared (820 nm). These penetrate the tissue to different depths, simultaneously capturing and depicting information originating from different retinal structures. The infrared reflectance (IR) image visualizes structures at the level of the outer retina and choroid. The green reflectance (GR) image allows imaging of retinal blood vessels, hemorrhages, and exudates. The blue reflectance (BR) particularly provides details of the inner retina and the vitreoretinal interface such as epiretinal membranes, retinal nerve fiber layer (RNFL) thinning, and macular pigment changes. The information from these three images is integrated to form a composite multicolor image.1 Color fundus photo
