[Apply of RetCam Ⅱ and color Doppler imaging in persistent hyperplastic primary vitreous].

Objective: To observe the manifestations of RetCam Ⅱ and color Doppler imaging (CDI) in a retrospective case series of persistent hyperplastic primary vitreous (PHPV).

Methods: Retrospective study. The medical records of 9 eyes/9 patients with PHPV went through RetCamⅡ and CDI from 2009 to 2014.

Results: There were 6 young boys and 3 young girl in this study, age from 2 months to 5 years. All the patients were born at full term. 9 eyes had complication (cataract). The manifestations of RetCam Ⅱ: There were pale in optic disc. There were white fibre rod connected with optic disc, then prolonged to vitreous cavity, connected with posterior lens capsule. CDI showed arterial blood stream signal in band-shaped echogenic structure within vitreous cavity, prolonged to lens from the optic disc, or showed funnel-shaped echogenic mass at the posterior surface of lens and anterior of vitreous body, adhered to ciliary body, lens and the optic disc.

Conclusions: PHPV is congenital ocular anomalies because of a failure of primary vitreous and the hyaloids vascular system to regress. It manifests as unilateral and boys. We diagnosis PHPV by RetCamⅡ and CDI.
