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 COMPARATOR

Participants 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.

Drug: Fluorescein Na 10% Inj 500mgDrug: Fluorescein Na 10% Inj 250mg

Half-Dose

EXPERIMENTAL

Participants 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.

Masking Details
The primary outcomes assessors will be retinal surgeons and residents, masked to the dosing of fluorescein. They will assess the subjective quality of images.

PARALLEL
Model Details: Patients will be randomly assigned to receive either a half-dose (250mg) or a full-dose (500mg) of intravenous fluorescein prior to their angiography procedure. If they return for a second fluorescein angiography study during the proceeding four months, they will receive the dose of fluorescein (250mg or 500mg) which they did not receive during their first study. Images will be evaluated subjectively by a masked panel of retinal surgeons for image quality, and image quality will be compared between images that are full dose and images that are half dose.
