Vitrectomy and Internal Limiting Membrane Peeling with and without Gas Tamponade for Myopic Foveoschisis

Advantages:

To conduct a comparison of clinical outcomes after vitrectomy and internal limiting membrane (ILM) peeling with and without gas tamponade for treatment of myopic foveoschisis (MF).

Methods:

In this retrospective, comparative case series, seventeen eyes of seventeen consecutive patients underwent vitrectomy and ILM peeling for treatment of MF. Eyes were divided into two groups, those with gas tamponade (n=9) and those without gas tamponade (n=8). Main outcome measures were the rate of resolution of MF measured by optical coherence tomography (OCT), the time interval until resolution of MF, and best-corrected visual acuity (BCVA).

Effectiveness / Safety:

After surgery, OCT showed a resolution of MF in 8 eyes (88.9%) in the gas group and 6 eyes (75.0%) in the no-gas group. The mean period until the resolution of MF was 2.25 months in the gas group and 4.50 months in the no-gas group (P=0.011). The mean BCVA improved significantly in both, the gas and no-gas groups (P=0.011 and 0.017).

Take home message:

Vitrectomy and ILM peeling without gas tamponade appears to be as effective for treatment of MF as vitrectomy with gas tamponade. However, eyes with gas tamponade showed a more rapid resolution of MF compared to those with no-gas tamponade.
