Fluorescein Angiography With a Full-dose Versus a Half-dose of Intravenous Fluorescein

Brief Summary
Fluorescein angiography is a common procedure used in ophthalmology to diagnose and monitor diseases of the eye. The standard dose of fluorescein dye used in fluorescein angiography is 500mg. It is common practice to give patients who have previously had an adverse reaction to fluorescein dye a half-dose, or 250mg, of fluorescein. It has been determined by our institution that anecdotally, there is no difference in image quality between the images created by a half-dose of fluorescein versus a full dose of fluorescein. Therefore, this study seeks to determine whether these doses are actually equivalent in terms of image quality. Patients who consent to participate in the study will be randomized to receive either a half or a full dose of intravenous fluorescein, and their images will be compared subjectively using a masked team of retinal surgeons and residents. We hypothesize that there will be no significant difference between the images obtained using a half-dose versus a full dose of intravenous fluorescein.

Outcome Measures
Primary Outcomes (1)
Subjective comparison of image quality between full-dose and half-dose fluorescein angiography performed on the same patient.
Participants who receive two clinically-indicated fluorescein angiography procedures within the time frame of the study will receive both doses of Fluorescein Na (250mg and 500mg). These two images will then be compared to each other in terms of image quality by a team of masked retinal surgeons.
Six months.
Secondary Outcomes (1)
Subjective comparison of image quality between full-dose and half-dose fluorescein angiography among all patients enrolled in the study.
One month.
Study Arms (2)
Full-Dose
ACTIVE COMPARATORParticipants in this arm will receive Fluorescein Na 10% Inj 500mg pushed over several seconds one time, prior to their fluorescein angiogram. If they return for a second (clinically indicated) angiogram, they will receive Fluorescein Na 10% Inj 250mg pushed over several seconds one time.
Half-Dose
EXPERIMENTALParticipants in this arm will receive Fluorescein Na 10% Inj 250mg pushed over several seconds one time, prior to their fluorescein angiogram. If they return for a second (clinically indicated) angiogram, they will receive Fluorescein Na 10% Inj 500mg pushed over several seconds one time.
Interventions
Full-dose intravenous Fluorescein Na prior to fluorescein angiography.
Half-dose intravenous Fluorescein Na prior to fluorescein angiography.
