[Visual functional changes in idiopathic macular holes treated by vitrectomy]

We evaluated visual functional measurements, visual acuity, central retinal sensitivity in a Humphrey field analyzer, and binocular function in Stereotest, Amsler grid testing, of 51 idiopathic macular holes before and after vitrectomy. In 36 of 51 eyes (71%) where the macular hole was closed after vitrectomy, there were improvements in all visual functional measurements postoperatively. The eyes in which the macular hole was closed had significantly better visual acuity before vitrectomy than those in which the hole was not closed. In 16 of 51 eyes that had visual acuity of less than 20/200 preoperatively, central retinal sensitivity before vitrectomy was higher in the eyes where the macular hole was closed than in those in which it was not closed. These measurements are useful for evaluation of visual functional improvements after vitrectomy and can help to choose candidates for macular hole surgery.
