ABSTRACT To determine visual and anatomic outcomes for patients with persistent fetal vasculature (PFV) observed or treated with surgery.
Retrospective interventional consecutive case series.
A total of 165 eyes of 150 patients diagnosed with PFV between January 1, 1983, and December 31, 2006, at the Bascom Palmer Eye Institute.
Patients with media opacity, progressive glaucoma, or retinal detachment who were deemed to have visual potential underwent lensectomy, 3-port vitrectomy, or both, through a limbal or pars plicata/plana approach.
Vision, postsurgical retinal attachment, lens status, need for eye removal, and rate of complications.
Of the 81 eyes that underwent surgical repair, 70 had at least 6 months of follow-up (median 47 months) and 49 (70.0%) had form vision, defined as finger counting, fix-and-follow, or better. Twenty (95.2%) of 21 eyes without form vision had a significant posterior component of PFV (P < 0.001). Forty eyes had limbal incisions, and 30 eyes had pars plicata incisions. The choice of surgical approach did not have a statistically significant effect on final visual acuity or rate of complications (P=0.43). Postoperative events occurred in 28 eyes (40.0%). Retinal attachment was achieved in 54 eyes (77.1%), and 61 eyes (87.1%) were left aphakic. Eighty-four eyes were not offered surgery, of which 78 eyes (92.9%) had a posterior component of PFV. The median age at diagnosis was greater compared with the surgical group (197 vs. 67.5 days, P=0.00545). Fifty-eight eyes (69.0%) lacked form vision, and 39 eyes (46.4%) had no light perception. Posterior manifestations of PFV, bilaterality, and microphthalmia were associated with poorer visual outcomes (P < 0.001, 0.041, and 0.002, respectively).
The majority of patients receiving surgical intervention for PFV achieved form vision. Posterior disease, microphthalmia, glaucoma, and amblyopia limited visual acuity outcomes even after aggressive intervention. The choice of limbal versus pars plicata approach produced similar visual and anatomic outcomes without a significant difference in rate of complications.

    ABSTRACT: Purpose: To discuss the potential role of microplasmin (ocriplasmin) as a surgical adjunct to vitrectomy in pediatric vitreoretinopathies. Methods: Literature review of the laboratory and clinical evidence to date for the use of both autologous plasmin enzyme as an adjunct to vitrectomy and more recently recombinant microplasmin (ocriplasmin) as monotherapy for focal vitreomacular traction in adults. Results: Autologous plasmin enzyme is currently being used as a surgical adjunct to vitrectomy, with supporting Levels 2 and 3 published evidence in a range of pediatric vitreoretinopathies including Stage 5 retinopathy of prematurity and congenital X-linked retinoschisis. The availability of autologous plasmin enzyme is limited. In recent Phase 3 clinical trials, intravitreal ocriplasmin versus sham injection resulted in resolution of focal vitreomacular traction in 27% versus 10% (P < 0.001, n = 652). Conclusion: Ocriplasmin may potentially be used as a surgical adjunct to vitrectomy in place of autologous plasmin enzyme. A Phase 2, randomized, placebo-controlled surgical trial is under way to assess this.

    ABSTRACT: Persistent hyperplastic primary vitreous (PHPV) is an ocular developmental disorder resulting from incomplete apoptosis of the embryonic hyaloid vasculature. Unilateral PHPV is traditionally associated with a poor prognosis because of the challenges associated with managing progressive anisometropic amblyopia. We report a child with unilateral PHPV who underwent cataract extraction, primary posterior capsulotomy with anterior vitrectomy and intraocular lens implantation followed by combined trabeculectomy/trabeculotomy within the first 8 weeks of life. Intensive optometric and orthoptic input was required over many years to manage increasing anisometropic amblyopia with final visual acuity of 20/40 unaided in the affected eye without evidence of glaucomatous optic neuropathy. This case illustrates the excellent visual outcome possible in a child with complex, unilateral PHPV using an intensive management approach comprising: early surgical intervention for congenital cataract and secondary glaucoma, meticulous monitoring of refraction, visual acuity and intraocular pressure, and motivated parents who engage in the management.

    ABSTRACT: Congenital cataract (CC) is the primary cause of treatable childhood blindness. Population-based assessments of prevalence and surgery age of CC, which are critical for improving management strategies, have been unavailable in China until now. We conducted a hospital-based, cross-sectional study of the hospital charts of CC patients younger than 18 years old from January 2005 to December 2010 at Zhongshan Ophthalmic Center (ZOC) in Guangzhou, China. Residence, gender, age at surgery, hospitalization time, and the presence of other ocular abnormalities were extracted and statistically analyzed in different subgroups. The search identified 1314 patients diagnosed with CC from a total of 136154 hospitalizations, which accounted for 2.39% of all the cataract in-patients and 1.06% of the total in-patients over the six-year study period. Of the identified CC patients, 9.2% had ≥2 hospitalizations due to the necessity of additional surgeries, with a total ratio of boys to girls of 1.75∶1. Based on a subgroup analysis according to age, patients 2-6 years old constituted the highest proportion (29.22%) of all hospitalized CC patients, and those 13-18 years old constituted the lowest proportion (13.47%) of the total number. The average age at surgery was 27.62±23.36 months, but CC patients ≤6 years old (especially ≤6 months old) became increasingly prevalent throughout the 6-year study period. A total of 276 cases (20.93%) of CC were associated with one or more other ocular abnormalities, the highest incidence rates were observed for exotropia (6.24%), nystagmus (6.16%), and refractive error (3.65%). In conclusion, CC patients accounted for 2.39% of all cataract in-patients in a review of 6 years of hospitalization charts from ZOC. The age at the time of surgery decreased over the 6-year study period, which probably reflects the continuing improvement of public awareness of children's eye care in China.
