Abstract: Purpose: Fundus fluorescein angiography (FFA) is usually done when the patient is on an empty stomach. In case, if the patient is not, their FFA is rescheduled for the next day to avoid the risk of complications. The purpose of this study was to compare the complications in patients who had undergone an FFA procedure on an empty stomach to those who had breakfast immediately before the procedure. Methods: In this study, 210 participants underwent FFA, of which 104 were fasting, and 106 had breakfast just before their procedure. In these two populations, we compare the immediate and post-procedure complications. Result: Patients who had FFA on an empty stomach were more likely to experience nausea and vomiting (11.32% vs 7.69%), skin allergies (1.89% vs 1.92%), and unconsciousness (0.94% vs 2.88%). In either the fasting or control groups, no complications were statistically significant (P>0.05). Conclusion: FFA is generally a safe procedure, however, previous studies have observed increased adverse events with people on empty stomachs. In individuals with various systemic disorders and diets, our study found no increase in adverse effects. Consequently, FFA shouldn’t be postponed in these individuals who are not on a diet or who have systemic co-morbidities.
