Abstract

Purpose To determine the feasibility of Ultra wide-field intravenous fundus fluorescein angiography (UWF-IV-FFA) in infants.

Methods A retrospective review of infants who underwent UWF-IV-FFA with the Optos P200MA was performed. The ability to capture different phases of the angiogram, the total image acquisition time and the presence of image artefacts were analysed.

Results Twelve infants with a variety of proliferative retinopathies underwent UWF-IV-FFA over a 7-month period. The mean age was 3.4 months (range 2–6 months) and the mean image acquisition time was 4 min (range 3–5). Pseudocolour fundus images and the venous, recirculation and late phases of UWF-IV-FFA were captured successfully in all infants (100%). Choroidal and arterial phases were captured in one (8.3%) and 10 (83.3%) infants, respectively. Image artefacts due to eyelashes and corneal desiccation occurred in nine (75%) and six (50%) infants, respectively. No adverse medical problems were noted.

Conclusions We have shown that UWF-IV-FFA can be successfully and safely performed in infants using the Optos P200MA system. It is a feasible new alternative to RetCam for obtaining an IV-FFA in the outpatients setting.
