Recovery from macular photostress and slow retinal potentials in cured retinal detachment.

After successful surgery for retinal detachment, a series of functional tests was performed, which primarily concerned the contact between photoreceptors and pigment epithelium. Even several months after reattachment the EOG still remained lower than in the fellow eye, when the macula was involved. If maximal visual acuity was reached with a formerly detached retinal area, the photostress recovery time was found to be delayed. The dc-coupled ERG showed distinct impairment of the c-wave in the eye with the reattached retina.
