Materials and Methods: 0.1-0.2 ml triamcinolone (Kenakort 40 mg), diluted 1:5, was carefully injected over the macular area under the fluid following core vitrectomy via standard 3-port sclerotomy in 11 patients (4 female, 7 male; mean age 67±8 years). ILM was peeled by using a forceps over the retinal surface in the form of maculorhexis while triamcinolone made ILM visible by specifically adhering it. C₃F₈ gas was used as internal tamponade at the end of surgery. Anatomic success was assessed by the help of optical coherence tomography and functional success was assessed by using Snellen visual acuity charts. Snellen visual acuity values were converted to logMAR equivalents for the statistical comparisons.

Results: Mean follow-up time was 9±3 months (range, 3-15 months). One eye was pseudophakic, ten were phakic. At the last examination, mean Snellen visual acuity (0.43±0.10) logMAR equivalent ~0.4), was higher than that of baseline (0.10±0.02) (logMAR equivalent:1.0) (p=0.005, Wilcoxon test). No complication was encountered during surgery. Macular hole was found closed in 10 (91%) eyes at the first attempt. The only eye with unclosed macular hole (9%) underwent a second PPV and the hole was closed at the last examination. Eight phakic eyes developed cataract and 7 of them underwent cataract extraction during the study period.

Conclusion: Triamcinolone acetonide is a useful adjunctive tool during PPV for macular hole by enhancing visibility of ILM and may result in successful outcomes.
