Recovery of retinal function after recent-onset rhegmatogenous retinal detachment in relation to type of surgery.
OBJECTIVE
To investigate retinal function and structure after recent-onset rhegmatogenous retinal detachment in relation to type of surgery.


METHODS
Thirteen consecutive patients with rhegmatogenous retinal detachment of <7 days' duration underwent vitrectomy surgery. Optical coherence tomography, full-field electroretinography (ERG), and multifocal ERG were performed preoperatively and 6 months postoperatively. Results were compared with those from a similar cohort of patients that had been treated previously with scleral buckling surgery.


RESULTS
Anatomic success was achieved in 10 patients, and follow-up was performed in 9. Similar to after scleral buckling surgery, multifocal ERG amplitudes in detached retina and fovea improved significantly at follow-up. Also similar to after scleral buckling surgery, full-field ERG rod function, combined rod-cone, and cone 30-Hz flicker amplitudes improved but significance was not reached. Full-field ERG responses remained reduced compared with normal. However, in contrast to after scleral buckling surgery, full-field ERG 30-Hz flicker implicit times were delayed at follow-up (P = 0.004), indicating a specific inner retinal dysfunction.


CONCLUSIONS
Previously not described, significant differences were seen in the pattern of regeneration of inner retinal function after vitrectomy compared with after scleral buckling surgery for recent-onset rhegmatogenous retinal detachment.
