Pulsatile polypoidal vessel in polypoidal choroidal vasculopathy is an important characteristic that has not been reported with any other chorioretinal diseases and could assist in understanding the pathogenesis of polypoidal choroidal vasculopathy, according to a study.
Akiko Okubo, MD, and colleagues at the Kagoshima University Graduate School of Medical and Dental Sciences in Japan reviewed the medical records of 84 eyes of 74 patients with polypoidal choroidal vasculopathy.
According to the study, seven of the 74 patients had polypoidal vessels (PV) in the macula. Four eyes had pulsatile PVs on the day of diagnosis, and PVs in the other three eyes showed pulsatile movement in the follow-up period. Two patterns of pulsatile movement were seen on indocyanine green angiography. Both appeared in the early frames of the angiography, and some could be seen during the first 15 minutes after the dye injection.
“The pulsatile movement disappeared spontaneously without treatment in some patients, and the period in which pulsatile PVs was detectable on indocyanine green angiography was limited in each patient,” the study stated.
The study is published in the August issue of Ophthalmology.
