Functional and Morphological Changes after Macular Pucker Surgery: An Optical Coherence Tomography and Microperimetric Study

Purpose: To investigate the relationship among functional and morphological findings before and after macular pucker surgery. Methods: Thirty-eight eyes with idiopathic macular pucker that underwent 25-gauge vitrectomy and infracyanine green-assisted internal limiting membrane peeling were prospectively enrolled. Main outcome measures were best-corrected visual acuity (BCVA), spectral-domain optical coherence tomography findings and MP-1 nnicroperimetry findings. Results: Mean BCVA improvement was 0.34 log-MAR (p <0.0001). Mean central retinal thickness (CRT) reduction was 50 [inn (p = 0.0041). Mean retinal sensitivity improvement was 0.9. Patients with a greater improvement of postoperative BCVA showed worse baseline BCVA (p < 0.001), shorter final inner/outer segment (IS/OS) interruption length (p = 0.039) and thinner final CRT (p = 0.035). Furthermore, final BCVA was correlated with baseline IS/OS interruption length (p = 0.001). Conclusion: Baseline BCVA, CRT and IS/OS integrity can be used to predict the functional outcomes after macular pucker surgery. (C) 2014 S. Karger AG, Basel
