[Macular buckling for highly myopic traction maculopathy].

To observe the efficacy of macular buckling in the treatment of highly myopic traction maculopathy. Retrospective case series study. The patients with high myopia who underwent macular buckling at the Zhongshan Ophthalmic Center of Sun Yat-sen University from June 2014 to June 2019 were enrolled, including 136 males and 212 females. The age was (56.68±11.59) years old. The outcomes measured included retinal reattachment rate, foveoschisis recovery rate, macular hole closure rate, postoperative best corrected visual acuity (BCVA), axial length (AL), and complications. The measurements were recorded preoperatively and at 1 month, 6 months, 1 year, 2 years, and 3 years postoperatively. The data was statistically analyzed using paired test. A total of 378 eyes were included, including 216 eyes with foveoschisis and macular detachment and 162 eyes with macular holes and macular detachment. Among them, 296 eyes underwent macular buckling, and the other 82 eyes underwent macular buckling combined with pars plana vitrectomy. During the follow-up period, 373 eyes (98.68%) achieved retinal reattachment; in patients with foveoschisis, 204 eyes (94.44%) were recovered; in patients with macular holes, 89 eyes (54.09%) achieved closure. All the postoperative results of BCVA were better than the preoperative value (1.459±0.841). BCVA continued to increase from postoperative month 1, remained stable at 1 year, and reached 0.908±0.606 at 3 years (=6.896, <0.01). All the postoperative results of AL were shorter than the preoperative value. The AL shortened by (4.423±1.740)mm at one month (=33.144, <0.01), increased gradually thereafter, remained stable at 1 year, and shortened by (2.101±1.643) mm at three years (=6.392, <0.01). The common complications included transient high intraocular pressure in 98 eyes (25.92%), epiretinal hemorrhage in 67 eyes (17.72%), and vitreous hemorrhage in 9 eyes (2.38%), which all resolved spontaneously within 1 month. In the early postoperative period, all patients had a certain degree of eye movement limitation, and 39 eyes (10.31%) had diplopia which resolved within 6 months without treatment. The strabismus surgery was arranged to treat esotropia in 6 eyes (1.58%). The macular buckle was removed from 1 eye (0.26%) because of the inability to tolerate diplopia. There were 8 eyes (2.11%) requiring a second operation to adjust the position of the buckle. The macular buckle was also removed from 4 eyes (1.05%) due to the implant rejection. Macular buckling can effectively shorten the AL, resolve posterior scleral staphyloma, and improve vision in the treatment of highly myopic traction maculopathy.
