Abstract
Purpose :
To evaluate the efficacy of vitrectomy using inverted inner limiting membrane flap technique for macular hole with retinal detachment, compared with vitrectomy using inner limiting membrane peeling method.
Methods :
We reviewed the medical records of the patients who were treated with vitrectomy for macular hole with retinal detachment, retrospectively. Nine patients were enrolled in the group of vitrectomy with inverted inner limiting membrane flap technique, and 12 patients were enrolled in the group of vitrectomy with inner limiting membrane peeling. The changes of visual acuities before and after surgery, closing rates of macular holes, and reattachment rates of retinas were investigated.
Results :
Macular holes were closed and retinal detachments were cured successfully in 8 eyes (88.8%) of the inverted inner limiting membrane flap technique group after vitrectomy. In the group of vitrectomy with inner limiting membrane peeling, macular holes were closed in 4 eyes (33.3%) and retinas reattached in 6 eyes (50%) after surgery. In the inverted inner limiting membrane flap technique group, mean best-corrected visual acuities were 1.61 logarithm of the minimal angle of resolution units before surgery and 1.02 after surgery. The postoperative visual acuities were significantly better than the preoperative visual acuities (P < 0.05). In the group of vitrectomy with inner limiting membrane peeling, significant changes in visual acuities before and after surgery were not observed.
Conclusions :
Higher closing rates of macular holes and reattachment rates of retinas, and improvements of postoperative visual acuities were found in the group using inverted inner limiting membrane flap technique. Vitrectomy with inverted inner limiting membrane flap technique for macular hole with retinal detachment was suggested a useful method than vitrectomy with inner limiting membrane peeling.
