摘 要：Background: Pathological myopia can be complicated by the presence of posterior staphyloma, macular atrophy, ruptures in Bruch’s membrane, pathologic choroidal neovascularization, and different degrees of myopic traction maculopathy. Purpose: To report the structural, functional and perfusional outcomes in patients underwent surgery for different stages of myopic traction maculopathy (MTM). Methods: A retrospective, consecutive, comparative, interventional, one-surgeon, case-control study was conducted in 46 eyes of 34 individuals between April 2015 and May 2021. Participants included normal emmetropic eyes (Control emmetropia, n = 25), healthy myopic eyes (Control high myopia, n = 20), and operated and structurally fully resolved myopic eyes with different stages of MTM (Surgically treated group, n = 46). Long-term postoperative functional and perfusional follow-up evaluations were performed with spectral domain-optical coherence tomography (SD-OCT) and OCT angiography. The primary outcome measure included long-term functional, structural and perfusion macular status across groups. Results: Forty-six eyes in 34 patients were included in the study group, with both eyes affected in 12 (26.3%) patients. The mean axial length was 29.89 ± 1.67 mm. The preoperative logMAR was 1.29 ± 0.54 and the postoperative logMAR was 0.60 ± 0.52 (P Conclusion: Compared to emmetropic and healthy myopic eyes, surgically-resolved MTM eyes generally have larger superficial foveal avascular zone area, lower vessel density, smaller choriocapillaris flow area, thinner central subfoveal thickness, and more macular defects. Eyes with stage III or IV MTM had larger deviation compared to eyes at earlier stages. Visual function change after surgery was associated with superficial foveal avascular zone area. Better functional, structural and perfusion index outcomes were observed when highly myopic eyes underwent early surgery.
