Outcomes after Failed Pneumatic Retinopexy for Retinal Detachment

Anatomic success rates for secondary PR, PPV, and SB+PPV after failed PR were lower than published success rates for their use in primary RD. This suggests that a failed primary PR selects for RDs that are inherently more difficult to reattach. There was a trend suggesting that anatomic success rates are greater with SB+PPV than PPV and, in turn, with PPV than repeat PR. However, these differences were not statistically significant and did not translate into better VA gains at 1 year for either procedure. The suitable procedure after failed PR thus depends on patient presentation, surgeon preference, and patient preference.
