Purpose:
To evaluate the anatomical and visual outcomes of patients who underwent pneumatic retinopexy by vitreoretinal fellows.
Methods:
We included 198 eyes (198 patients) that underwent pneumatic retinopexy by vitreoretinal fellows at a single academic institution between November 2002 and June 2016. Main outcomes were single-operation success and final anatomical success in retinal reattachment, as well as visual acuity at 3 months and 6 months after treatment.
Results:
Single-operation success rate was 63.6% at 3 months and 59.5% at 6 months. Final anatomical reattachment was achieved in 92.9% (n = 184) and 96.6% (n = 143) at 3 months and 6 months, respectively. Logarithm of the minimum angle of resolution visual acuity improved from 0.72 ± 0.1 (∼20/100 Snellen) at baseline to 0.36 ± 0.06 (∼20/40 Snellen) at 6 months (P < 0.001). There was no statistical difference in anatomical success rates or visual outcomes between cases performed by first- or second-year fellows (P > 0.50). Single-operation success was associated only with size of detachment (P = 0.01). Visual outcome was associated with macula status at baseline (P = 0.032) and number of reoperations (P < 0.001).
Conclusion:
Anatomical and visual outcomes of fellow-performed pneumatic retinopexy are comparable with those reported in the previous literature.
