This systematic review and meta-analysis evaluated the incidence of postoperative hypotony following retinectomy in rhegmatogenous retinal detachment surgery, analyzing 33 studies with 2673 eyes. The pooled incidence of hypotony was found to be 13.71% (95% CI, 10.40-17.40). The study also explored factors influencing hypotony risk and its association with visual outcomes.
Key findings
- The pooled incidence of postoperative hypotony was 13.71% (95% CI, 10.40-17.40).
- Stricter hypotony definitions and later assessment timepoints were linked to higher incidence rates.
- A significant negative correlation was found between hypotony incidence and visual improvement rates (Spearman ρ = -0.47, p = 0.03).
Why it matters
Understanding the incidence and risk factors for postoperative hypotony is crucial for clinicians managing patients undergoing retinal detachment surgery, as it can significantly impact visual outcomes and patient recovery.
