Molloy, L. B. (2011). Implications of post operative visual loss: Steep trendelenburg and effects on intraocular pressure. AANA Journal, 79(2), 115-120.
This study involves a concrete analysis of the effects of postoperative visual loss. The title covers the whole research paper and is appropriate in the representation of the whole case study. The research was carried out for three years of collecting data. The participants were patients who had a history of eye problems such as disease or had surgery in their eyes. Patients who had diabetes were excluded from other illnesses such as hypertension and vascular problems.
The time of data collection was sufficient to conduct the experiment and make the observation. The participants were important, as they were patients who had the condition and they excluded patients with further illnesses that would affect the outcome, therefore, making the samples reliable. The study sample was 37 patients, with women being 21 and men 16. The mean age was 50 and the participants were from age 31 to 78. The study group is small and there was a need to have a bigger sample of over 100 participants. An assumption had been made that the age range and sample size were sufficient. In addition, the age range did not consider the young who have eye problems, like the teens, children, and young adults.
Another challenge, the study, took place only in one hospital and depended on the experience of a few specialists. The research question was adequately answered as the researchers determined that ophthalmic safety can be improved by measuring the IOP. This finding is crucial to the medical profession and nursing being included. The study, however, should have recommended further studies based on the obvious limitations.
