Visual and morphological outcomes of vitreomacular traction syndrome in retinitis pigmentosa treated by vitrectomy

Retrospective review of 13 eyes that had undergone pars plana vitrectomy (PPV) for vitreomacular traction (VMT) syndrome in retinitis pigmentosa (RP) and had a postoperative follow-up period ≥9mo in order to evaluate whether it is necessary to treat VMT in RP by vitrectomy. The 13 RP eyes suffering from VMT were evaluated by means of best corrected visual acuity (BCVA), anterior and posterior binocular examination, spectral-domain optical coherence tomography (SD-OCT) before and after operation. We detected that although vitrectomy could improve the macular morphology in some RP patients with VMT, visual outcomes might be limited and unpredicted most likely because of the long-standing retinal dysfunction, but the vitrectomy is necessary in order to remain or improve the central vision in some cases.
