PURPOSE: To identify the major traction mechanisms that cause myopic traction maculopathy and to determine whether surgery can be tailored successfully to the specific mechanism involved. DESIGN: Nonrandomized, retrospective, interventional case series. METHODS: We performed a chart review of consecutive patients who underwent vitreoretinal surgery for myopic traction maculopathy by a single surgeon at a tertiary referral center. Traction mechanisms were identified based on preoperative and intraoperative findings and postoperative response to a tailored surgical approach. RESULTS: Six eyes of 6 patients with a minimum follow-up of 6 months were included. Major pathogenic traction mechanisms included perifoveal posterior vitreous detachment with vitreomacular traction in 3 eyes, noncompliance of native internal limiting membrane in 2 eyes, epiretinal membrane in 1 eye, and remnant cortical vitreous layer after posterior vitreous detachment in 1 eye. One eye exhibited 2 traction mechanisms. The surgical approach addressed only the major traction mechanism(s) identified in each eye. After surgery, the visual acuity improved by 2 lines or more in all eyes, and macular thickening resolved completely in 5 (83%) of 6 eyes and partially in the remaining eye. CONCLUSIONS: The traction mechanisms causing myopic traction maculopathy are diverse. Vitreoretinal surgical repair for this condition is successful when the major traction mechanisms causing tautness of the inner retina are identified and relieved.
