[Results of vitreous surgery for idiopathic macular holes and retinal sensitivity]

We evaluated the visual outcome in 16 eyes with idiopathic full-thickness macular holes. Phacoemulsification and posterior chamber intraocular lens implantation was also performed, if cataract was present. Closure of the macular hole was obtained in 12 eyes, 75%. Postoperative visual acuity improved by 2 lines or more in 14 eyes, (87.5%), 0.5 or better in 9 eyes, (56.2%), and 0.8 or better in 6 eyes, 37.5%. The correlation values between postoperative visual acuity and size of hole, % decrease of macular retinal sensitivity, macular retinal sensitivity, preoperative visual acuity, size of fluid cuff, and duration were -0.766, 0.710, 0.696, 0.676, -0.665, and -0.313, respectively. Measurement of macular retinal sensitivity with macular hole size could be very useful for predicting postoperative visual acuity.
