Ultrasonographic feature of persistent hyperplastic primary vitreous
Eye Science
|May 28, 2015
Summary
Ultrasonography reveals characteristic retrolental masses in persistent hyperplastic primary vitreous (PHPV). These findings aid in diagnosing PHPV, especially when fundus examination is difficult.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Persistent hyperplastic primary vitreous (PHPV) is a congenital developmental anomaly of the eye.
- Diagnosis can be challenging due to media opacity, hindering fundus examination.
Purpose of the Study:
- To observe and characterize the ultrasonographic features of persistent hyperplastic primary vitreous (PHPV).
Main Methods:
- Thirty-two subjects (34 eyes) diagnosed with PHPV underwent ultrasonographic evaluation.
- Ultrasonography provided real-time display of intraocular structures.
Main Results:
- Ultrasonography identified retrolental masses in PHPV patients.
- Masses extended from the optic disc to the posterior lens capsule.
- Characteristic shapes observed included band, regular triangle, and inverted triangle echoes.
Conclusions:
- Ultrasonography is a safe, noninvasive tool for diagnosing PHPV, particularly in uncooperative patients or those with media opacity.
- Ultrasonographic features help evaluate lesion size, position, and severity.
- Findings assist in surgical planning and prognosis determination for PHPV.
