Purpose:

To evaluate immediate and short term functional and anatomic changes of using the 25-gauge pars plana vitrectomy (25G-PPV) for epiretinal macular membranes (ERM).

Methods:

Prospective study of a consecutive interventional case series. Ten eyes of 10 phakic patients with idiopathic ERM and clear media underwent 25G-PPV and ERM removal with indocyanine-green assisted internal limiting membrane (ILM) peeling. ETDRS best correct visual acuity (BCVA), intraocular pressure (IOP), surgical induced corneal astigmatism (SIA), macular optical tomography and postoperative complications were evaluated after 24 hours, 1 week and one month.

Results:

Mean BCVA remained stable the first postoperative day, the first week ( p>0.05), and improved after 1 month (p<0.05), as compared to preoperative values. IOP remained stable during the follow up (p=0.25); SIA was extremely low at each timepoint; macular thickness remained unaffected after 24 hours (p>0.05) and reduced significantly after 1 week (p<0.05). No complications were observed.

Conclusion:

The 25G-PPV seems to be practical and safe for ERM on a short term basis. It prevents any SIA, allowing good immediate anatomical and functional outcomes.

Take-home message:

The 25G-PPV for ERM seems to prevents any SIA, allowing good immediate anatomical and functional outcomes.
