Purpose: Surgical intervention in cases of total retinal detachment associated with ROP remains controversial. We aim to quantify the long term visual function achieved following successful surgery for retinal detachment in a child born at 23 (+days) weeks gestation Methods: A child born at 23 weeks developed stage V ROP., and was operated upon at the age of 18 months. Four years after surgery visual acuity outcome was assessed using the Teller Acuity Cards with an operant conditioning strategy. Function of the central retina and anterior visual pathways were assessed using flash and pattern visual evoked potentials (VEPs). Results: The retina remains flat 4 years after surgery . Despite significant developmental delays and limited communication, gratings subtending 1.4 c/deg (6/130) were reliably indicated.VEPs with normal amplitudes were clearly reproducible to both flash and large pattern reversal checkerboards but showed marked delays consistent with limited foveal development. Conclusions: A functional visual pathway form the retina to the visual cortex has been demonstrated for luminance and large pattern stimuli following surgical repair of longstanding retinal detachment associated with stage 5 ROP. Visual resolution also supports the assessment of useful but subnormal vision
