Retinal fluorograms using oral fluorescein
Ophthalmology
|August 1, 1980
Summary
Oral sodium fluorescein offers a safe alternative to intravenous injection for retinal angiography. This method is beneficial for pediatric patients and those with difficult venous access, enabling effective documentation of retinal vascular leakage.
Area of Science:
- Ophthalmology
- Medical Imaging
- Pharmacology
Background:
- Sodium fluorescein angiography is a standard diagnostic tool for retinal vascular diseases.
- Intravenous administration is the conventional method, but can be challenging in certain patient populations.
Purpose of the Study:
- To evaluate the safety and efficacy of oral sodium fluorescein administration for retinal angiography.
- To compare oral administration with traditional intravenous injection.
Main Methods:
- Administration of sodium fluorescein orally to study participants.
- Performance of fluorescein angiography to assess dye leakage.
- Measurement of serum dye concentrations over time.
Main Results:
- Oral sodium fluorescein was safely administered.
- Angiograms effectively documented dye leakage, comparable to intravenous injection.
- Serum dye concentrations plateaued within one hour, similar to intravenous levels.
Conclusions:
- Oral sodium fluorescein is a safe and effective alternative for retinal angiography.
- This route is particularly advantageous for children and patients with venous access difficulties.
- It facilitates studies of late-onset retinal vascular leakage, including cystoid macular edema.
