Ophthalmology and vision science research: part 2: How to commence research--Eureka or that's a little unusual?

Understanding the key elements that increase the likelihood of project success is fundamental for those embarking on research. The first article in this series placed scientific journals in perspective in relation to Journal Impact Factors and citation indices. This second article in a series primarily aimed at those commencing research, particularly in the area of ophthalmology and vision science, delineates the interrelated components that are required to complete a research project. Successful research projects seldom emerge from serendipitous observation, and most evolve through a combination of inspiration, careful planning, and a great deal of industry. Beginning researchers must first be clear about their reason(s) for pursuing research and should identify potential mentors and collaborators at the outset. This article discusses methods of identifying suitable projects and mentors. Ten component areas necessary to complete a research project are addressed, with reference to relevant published literature, under the following topic areas: mentors and collaborators; finding a research topic; confirming suitability of the topic; defining the research question; developing the hypothesis; key considerations in study design; threats to study validity; study sample size; benefits and limitations of clinical science; completing to publication. This guide is intended to be applicable to all embarking on research, but particularly to those with an interest in the visual system. The final 3 articles in this series will deal with writing a research paper to publication standard, working successfully with the journal review process, and refining electronic literature searches.
