This is especially important in individuals who are uncooperative or unsuitable for fundus examination due to media opacity. Combined with clinical feature, ultrasonography provides vital evidence for the diagnosis of PHPV..Thought observing ultrasonographic feature, clinicians could evaluate the size, position and severity of lesions in PHPV patients,.and which would be helpful to determine the surgical approach and clini-cal prognosis.展开更多

Posterior PHPV was treated with lensectomy,posterior vitrectomy,retinal photocoagulation,and IOL implantation or silicone oil tamponade. Visual acuity（VA）,pattern visual evoked potential（P-VEP）,anatomic recovery,postoperative complications,and amblyopia outcome were examined.Subjects were followed-up for 3-48 mo after surgery.RESULTS：Of the 30 patients（33 eyes）with congenital cataract and PHPV included（average age,39.30±35.47mo）,9 eyes had anterior PHPV and 24 had posterior PHPV. Thirty-two eyes were surgically treated. Eyes with anterior PHPV received an IOL during one-stage（6 eyes）and twostage（3 eyes）implantation. Postoperative complications included retinal detachment（1 eye）and recurrent anterior chamber hemorrhage（1 eye）. In eyes with posterior PHPV,6 and 11 eyes received IOLs in one-and two-stage procedures,respectively. Silicone oil was retained in 2 eyes,and IOLs were not implanted in 4 eyes. VA significantly improved in 25 eyes following operations and 3-48 mo of amblyopia treatment. P-VEP P_（100） was improved following surgery in both PHPV types.CONCLUSION：Our surgical strategies are appropriate and effective for anterior and posterior PHPV. Early surgical intervention and amblyopia therapy result in positive treatment outcomes.展开更多
