Vitrectomy in vitreomacular traction syndrome evaluated by ocular coherence tomography (OCT) retinal mapping.

PURPOSE: To evaluate vitreomacular traction syndrome with ocular coherence tomography (OCT) retinal mapping before and after vitrectomy.

METHODS

A prospective study of 11 eyes with vitreomacular traction syndrome was carried out. Ocular coherence tomography retinal mapping was performed before vitrectomy and 6 months postoperatively. Visual acuity (VA) was measured with the ETDRS chart.

RESULTS

All patients showed a reduction in the thickness of the macular area postoperatively. The mean thickness in the central macular area was 609 microm preoperatively and 243 microm 6 months postoperatively (p < 0.001). Ten patients had an increase in VA of at least two lines on the ETDRS chart and in one patient VA was unchanged. The mean improvement in VA was 3.1 lines.

CONCLUSION

Retinal mapping with OCT is a good method of evaluating the thickness of the macula before and after surgery in vitreomacular traction syndrome and vitrectomy improves VA in most cases.
