The Use of Prostaglandin Analogues and Cystoid Macular Edema after Uneventful Cataract Surgery: A Systematic Review and Meta-Analysis.

PURPOSE

To evaluate whether using prostaglandin analogues (PGAs) perioperatively is associated with an increased rate of the development of clinical or subclinical cystoid macular edema (CME) after uneventful cataract surgery.

METHODS

The PubMed, Scopus, and ScienceDirect databases were searched to June 2022 for this systematic review and meta-analysis. Two authors independently screened search results. Random-effects meta-analyses were performed to calculate the overall incidence rate and odds ratio (OR). Quality of studies was assessed using the modified Newcastle-Ottawa scale. The incidences of CME for continued discontinued use of PGAs perioperatively, continued use of PGAs, discontinued use of PGAs, and PGA users non-PGA antiglaucomatous users were main outcomes.

RESULTS

Out of 544-articles, 9 studies that met the inclusion criteria were analyzed. The continued use of PGAs was not associated with an increased risk of the development of subclinical macular edema compared with discontinued use (OR = 1.32 [95% Confidence Interval (CI) = 0.49-3.51], .582). The overall incidence of CME was 34% (95% CI = 0.17-0.52) for continued use of PGAs and 7% (95% CI = 0.02-0.13) for discontinued use of PGAs. Using PGAs did not increase the risk of CME's development compared with non-PGA antiglaucomatous usage (OR = 2.29 [95% CI = 0.84-6.23], .103).

CONCLUSIONS

Discontinuing treatment with PGAs during the perioperative period in eyes without any known risk factors for CME has no clinically significant effect on reducing the development of postoperative CME based on the existing studies. Further, well-designed randomized controlled trials need to be performed.
