PURPOSE: To evaluate fluorescein angiography (FA) in eyes with aggressive posterior retinopathy of prematurity (AP-ROP).
DESIGN: Retrospective, nonrandomized case series.
PARTICIPANTS: Three patients (6 eyes) with AP-ROP.
METHODS: Three patients (6 eyes) diagnosed with AP-ROP during ROP screening between July 2007 and July 2008 were included in this study. Fundus photographs and FA were obtained before and after laser and surgical treatment using a wide-field digital pediatric imaging system.
MAIN OUTCOME MEASURES: Fluorescein angiography and fundus photographs.
RESULTS: At the initial stage of AP-ROP, FA showed vascular abnormalities, including capillary nonperfusion throughout the vascularized retina, shunting in the vascularized retina, a circumferential demarcation line, and limited vessel development, which was difficult to identify only by ophthalmoscopy. After treatment, FA showed poorly developed retinal vessels, including 4 small major vessels without an arcade pattern, small macular vessels, an inhomogeneous capillary bed, and absence of a capillary-free zone in the fovea.
CONCLUSIONS: Capillary bed loss throughout the vascularized posterior retina is characteristic of AP-ROP and may exacerbate retinopathy.
