Background: Myopic traction maculopathy (MTM), also known as myopic foveoschisis typically occurs in highly myopic eyes often leads to blindness. The pathologic features of foveoschisis may be alone or it may be associated with foveal detachment or macular hole. Aim of the work: To assess the role of vitrectomy with internal limiting membrane (ILM) peeling in changing visual outcomes and optical coherence tomography (OCT) findings of the macula in patients with myopic vitreo-macular traction syndrome. Design of the study: prospective Interventional case series. Methodology: 19 high myopic eyes of 17 patients divided into 3 groups: Group 1 (Foveoschisis only): (6 eyes) Group 2 (foveoschisis and foveal detachment): (6 eyes) Group 3 (foveoschisis, foveal detachment and macular hole): (7 eyes) Results: In our study, the visual acuity significantly improved in all eyes at 6 months postoperatively. This was associated with significant reduction of central foveal thickness. There was statistically significant inverse correlation between changes in best corrected visual acuity (BCVA) and both basal refraction and basal BCVA. There was statistically significant direct correlation between changes in central foveal thickness (CFT) and basal refraction. On the other hand, there was significant inverse correlation between changes in CFT and basal CFT. Conclusion: Visual improvement was better in foveoschisis with foveal detachment eyes than in foveoschisis or macular hole eyes.
