Abstract:
Objective To observe the efficacy of pars plana vitrectomy with internal limiting membrane (ILM) peeling and gas tamponade in the treatment of myopic macular retinoschisis (MF).Methods This is a retrospective case study.A total of 35 MF patients (36 eyes) were enrolled in this study.There were 5 males (5 eyes) and 30 females (31 eyes),with an average age of (60.13 ± 10.00) years.All patients were examined for best corrected visual acuity (BCVA),diopter,optical coherence tomography (OCT) and axial length.The patients were divided into a MF group (group A,10 eyes),MF with foveal detachment group (group B,12 eyes) and MF with lamellar macular hole group (group C,14 eyes) according to the OCT characteristics.There was no difference of age,gender,spherical equivalent refraction and axial length among 3 groups (F=0.020,0.624,0.009,0.195;P＞0.05).There were significant differences of the minimum resolution angle logarithm (logMAR) BCVA and central fovea thickness (CFT) (F=11.100,41.790;P＜ 0.05).All patients underwent pars plana vitrectomy with ILM peeling and gas tamponade.The follow-up was more than one year.The BCVA and macular structure at the final follow-up were analyzed.The efficacy between 3 forms of MF was compared.Results At the final follow-up,the BCVA was 0.40±0.44 and CFT was (213.35±97.58) μm,which were significantly improved compared with preoperative measurements (t=5.984,5.113;P＜0.001).MF was resolved in 33 eyes.In group A,B and C,the logMAR BCVA were 0.13 ± 0.10,0.73±0.33 and 0.38± 0.52,respectively;CFT was (222.40± 57.16),(212.50 ± 150.45),(206.67 ± 55.97) μm,respectively;MF was resolved in 10,11 and 12 eyes,respectively;complete ellipsoid was observe in 8,2 and 12 eyes.The logMAR BCVA (F=6.750,P=0.003) and the rate of complete ellipsoid (x2=18.590,P＜0.001) in group B was lower than group A and C,the differences were significant.There was no difference of CFT (F=0.068,P=0.935) and the rate of MF resolving (x2=1.558,P=0.459) among the three groups.One eye (1/14) in group C suffered from full layer macular hole.Conclusion Pars plana vitrectomy with ILM peeling and gas tamponade is effective in the treatment of myopic macular retinoschisis.The macular structures and BCVA are worst in eyes with foveal detachment.
