Performing vitrectomy in stage 5 retinopathy of prematurity is
controversial, partially due to limited anatomical and poor reported visual
results. Fifty-five eyes of 50 patients whose retinas were reattached by
open-sky vitrectomy in stage 5 retinopathy of prematurity and who were
followed up for more than 12 months were analyzed retrospectively to
ascertain clinical factors that may influence visual outcome. Vision was
evaluated by preferential looking. Visual ability to discriminate
stationary objects was obtained in 32 (58.2%) eyes, 18 (32.7%) had motion
perception, and five (9.1%) had light stimulus perception. Although visual
acuities were relatively low, they were useful to these patients. Age at
the time of vitrectomy and the shape of the retinal detachment were found
to be important factors in predicting visual prognosis.
