Postoperative Perfusion Findings in Highly Myopic Eyes: Case Series Report

Purpose: To examine the structural, functional, and perfusion immediate outcomes and long-term correlated follow-up perfusional outcomes in surgical patients at different stages of myopic traction maculopathy (MTM). Methods: We performed a retrospective, comparative, interventional, one-surgeon, case-control study in 6 eyes of 6 patients enrolled between May 2018 and December 2021. Three groups of eyes were examined: one normal emmetropic eye (Control emmetropia), one healthy myopic eye (Control high myopia), and 4 operated and structurally fully resolved myopic eyes with different stages of MTM (Surgically treated group). Long-term follow-up postoperative functional and perfusion evaluations were performed with spectral domainoptical coherence tomography (SD-OCT) and OCT angiography. Results: Six eyes of 6 patients were included in the study. In the surgical group the stage distribution was one eye at each stage of myopic traction maculopathy. The preoperative BCVA was 1.29±0.54 logMAR, and the postoperative BCVA was 0.60±0.52 logMAR (P<0.05), the axial length was 30.49±1.87 mm with a mean time to surgery of 19.3±16.21 months. The difference in perfusion indices across groups was statistically significant (p<0.005). Conclusion: Better functional, structural and perfusion indices outcomes were observed when highly myopic eyes underwent surgery early. Due to the risk of developing irreversible vision loss when undergoing surgery in late stages of this condition, longitudinal fellow-eye structural and perfusional evaluation is advised to detect early stages of MTM and make a suitable surgical decision to optimize the visual outcomes.
