The title of this article indicates the focus of the research. “Implications for postoperative visual loss (POVL)” gives a clue on the direction of the study. The reader can tell that the research explores the subject of postoperative visual loss. In addition, the extension of the heading; “Steep Trendelenburg position (ST) and effects on intraocular pressure (IOP)” informs the reader of the variables under study. The reader learns that the research focuses on the effects of ST on IOP, and how these variables relate to relate POVL. The abstract does not summarize all key features of the study. It gives a general overview of the study. The abstract gives an explanation of the variables under study, the duration of the study, the mode of the study, and its findings. However, the abstract fails to illustrate the study methodology and a brief explanation of the study results.

Moreover, the hypothesis of the study appears concise, significant, and researchable. The hypothesis enables the reader to comprehend the significance of this study. The hypothesis challenges an existing view that “cerebral and ophthalmic circulatory autoregulation prevents elevated compartments pressure and reductions in perfusions” (Molloy, 2011). The hypothesis indicates the variables under investigation which prove to be researchable. The author cited the latest sources in his literature review. However, the author also cited several ancient sources. Most of the references were secondary sources.

The research design employed repeated-measures, prospective design; an appropriate method for this study. The researcher designed measures to gauge the validity of the data collected. The accuracy of the data collected seemed to pose a threat to the validity of the data. However, each variable had a mechanism in place to monitor its activity. Variables included IOP, OPP, ST, and CPV. The statistical analysis of the data provided statistics such as means, standard deviation, and frequencies which can be used for replication. The author utilized theoretical framework as a means of revealing to the readers its relation to his study. The author gives substantial information on incidences of POVL and possible risk factors. The author provides an overview of studies carried out earlier and how they relate to POVL. The risk factors and studies provided enable the reader to have a tremendous picture of POVL.
