Surgical results of persistent hyperplastic primary vitreous

Ophthalmology. 1999 Feb;106(2):280-4. doi: 10.1016/S0161-6420(99)90066-0.


Purpose: To evaluate the surgical success of patients with persistent hyperplastic primary vitreous (PHPV) and to identify preoperative indicators of visual outcome.

Design: Noncomparative case series.

Methods: The diagnosis of PHPV was made in 35 eyes of 27 patients from 1982 to 1994. In each case, anterior and/or posterior PHPV findings, preoperative testing, surgical procedures, and visual outcomes were documented. Twenty-nine of 35 eyes were managed surgically. Follow-up ranged from 2 months to 12 years.

Results: Of the 35 eyes, 2 (5.7%) had strictly anterior PHPV, 8 (22.9%) had strictly posterior PHPV, and 25 (71.4%) had components of both anterior and posterior disease. Initial lensectomy and vitrectomy was performed in 24 eyes (68.6%). Surgery was withheld in four eyes secondary to severity of disease with an unrecordable visual-evoked potential (VEP). Reoperation rate was 32.3% for membrane reproliferation, glaucoma, vitreous hemorrhage, retinal detachment, or strabismus. Best-corrected final visual acuity ranged from 20/60 to no light perception. Six eyes (17%) maintained Snellen visual acuity despite posterior PHPV with some degree of retinal dysplasia.

Conclusions: Surgical treatment of PHPV can result in functional visual outcome despite posterior segment involvement. The degree of ocular malformation, however, will ultimately limit the amount of visual improvement. Preoperative testing, including VEP, may aid in determining surgical candidates.
