Abstract The aim of the work: To evaluate the efficacy of pars plana vitrectomy (PPV) in cases of diabetic macular oedema unresponsive to laser treatment, and to demonstrate the differences in the anatomical and functional outcomes between pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and without peeling. Material & Method: Twenty patients with persistent clinically significant macular oedema despite laser treatment were recruited for this study. Clinical assessment included determination of the best corrected visual acuity, fllorescein angiography, and optical coherence tomography.8 patients underwent PPV with removal of the posterior hyaloid alone, and 12 patients underwent PPV and ILM peeling. The follow up was 6 months. Results: By the six month postoperatively, significant improvement in the BCVA, and significant decrease in the central foveal thickness were seen in both the peeling and the non peeling group. The decrease in the central foveal thickness was greater in the ILM peeling group than the non peeling group (P<0.05).No statically significant difference in the improvement in the BCVA between both groups (P>0.05). Conclusion: In spite of the greater structural improvement after PPV with ILM peeling, the functional (BCVA) improvement is similar to that shown after PPV without ILM peeling. |
