Abstract
Purpose::
To report the anatomical closure rate and visual outcome of macular hole surgery, in eyes that previously had failed macular hole surgery.
Methods::
Retrospective analysis of medical notes. 27 patients were included in this study. 27 case notes were reviewed, including 28 operations on eyes that previously had failed macular hole surgery. All the operations were performed or directly supervised by two surgeons. The mean age of the patients involved in this study was 68.25 years (45-80). 7 eyes had stage 2 macular holes, 10 stage 3, 4 stage 4 (7 eyes were not staged).The mean duration of patient symptoms was 10 months (1-35 months). The mean clinical follow up for these patients was 5.96 months (3 weeks - 26 months).
Results::
The macular hole closure rate was 84.6%. 26 operations were performed with platelets, 1 without (1 not known). 24 eyes had inner limiting membrane (ILM) peel, 1 did not (1unknown). The mean preoperative logMAR visual acuity (VA) was 0.91(0.3-1.6) and the mean post op VA was 0.68 (0.18-1.6). The mean VA improvement postoperatively was 0.27 (-0.6 to +1.0). All stage 2 holes, 90% of stage 3 and 75% of stage 4 closed after the second operation.
Conclusions::
Re-operating on eyes that had previously failed macular hole surgery, has a high success rate especially with stage 2 macular holes and can lead to a significant visual improvement (up to 1.0 on the logMAR scale).
