Abstract: 

Purpose: To identify clinical characteristics associated with outcome of treatment in PFV based on a modified classification.
Methods: In this noncomparative case series, 54 eyes of 47 consecutive patients with PFV managed from 1981 to 1998 at a tertiary eye hospital were reviewed. Pars plicata lensectomy and vitrectomy was performed in 34 eyes and translimbal lensectomy and vitrectomy in 5 eyes. Fifteen eyes were managed non-surgically. Measured outcomes were visual improvement and cosmetic acceptability. Visual improvement was defined as at least one Zipf's category improvement of best corrected final vision as compared with initial visual acuity, provided that final vision of CSUM (central, steady, unmaintained equal to 20/100-20/30) was obtained. Cosmetic acceptability was defined as absence of small orbit, externally small appearing eye with microcornea and hypotony, eye deviation more than 35 prism diopters without strabismus surgery, and corneal opacity.
Results: Excluding six inoperable eyes, in 10 out of 33 operated eyes (30.3%) improvement of vision was obtained including 4 eyes with anterior PFV and 6 eyes with combined PFV. In the univariate analysis, factors such as anterior form of PFV, performing surgery in combined form and having a normal retina, had weak association with a higher chance of visual improvement. In multivariate regression analysis the chance of developing an unacceptable cosmetic appearance was higher in females than males (OR=10.5), and also in bilateral cases (OR=7.9). Offspring of consanguineous marriages had a more severe form of PFV.
Conclusion: Although visual potential is limited in PFV, some eyes with anterior or combined form and normal retina achieved improvement of visual acuity after surgery. However, statistically no single factor except gender and bilateral PFV (for cosmetic unacceptability) could effectively predict results of treatment. Therapy should be individualized based on clinical findings. Genetic studies in offsprings of consanguineous marriages with PFV may prove informative.
