Ultrasonographic Findings of Persistent Hyperplastic Primary Vitreous

ABSTRACT

We analyzed 33 patients (39 eyes) who were surgically diagnosed as persistent hyperplastic primary vitreous (PHPV) with standardized B-scan ultrasonography. The eyes were evaluated for vitreous stalk or membrane, retrolental proliferation, retinal fold, vitreous opacity, and retinal detachment (64.1 %, 48.7 %, 15.4 %, 15.4 %, and 5.1 %, respectively) with the results. We classified these findings of PHPV into 5 types as follows, type 1 simple retinal fold or preretinal fold alone; type 2 retrolental proliferation alone; type 3 vitreous stalk or membrane; type 4 retrolental proliferation connected with vitreous stalk or membrane; type 5 complicated retinal detachment. The incidence of these types were 15.4%, 15.4%, 28.2 %, 33.3 %, and 5.1 %, respectively. Ultrasonographic findings would be used as a useful parameters to evaluate, document, and plan the management in PHPV.
