Conclusion
SO tamponade, tamponade
RETINA
This research indicated that SVD and SPD were lower in eyes with SO tamponade than in contralateral eyes. SVD and SPD were increased in the macular region of the eyes with SO tamponade and removal. BCVA (LogMAR) decreased while SVD and SPD increased in the macular region after SO removal; BCVA (LogMAR) was negatively correlated with macular SVD and SPD values, suggesting an improvement in visual acuity after SO removal. Gas tamponade may not significantly affect early vascular changes, but more data are needed to support this notion. Future studies are warranted to explore the mechanism underlying retina microcirculation changes in eyes administered SO tamponade.
