Purpose: To determine if OCT 3 measured or calculated parameters are predictive of post-operative best-corrected visual acuity in patients with closed macular holes. Methods: Retrospective case study reviewing patients who have undergone successful macular hole surgery. Patients were evaluated clinically and with OCT 3 at least 3 months following surgery. BCVA was obtained at the time of exam. 17 eyes of 16 patients met inclusion criteria. Horizontal 6 mm OCT 3 scans were analyzed using the retinal thickness/ volume analysis package. All calculated parameters including minimum fovea thickness(microns), average fovea thickness, average macula thickness with respect to temporal, superior, nasal, inferior, inner, and outer quadrants and the respective volume(cubic mm) parameters were analyzed to determine a correlation with visual acuity. The fovea contours were classified by the authors into "smooth" or "irregular" categories and analyzed for correlation with BCVA. Results: Post operative BCVA ranged from 20/25 to 20/400 with an average of 20/48. Minimum fovea thickness ranged from 97 to 422 (average 175.5 microns). Pearson correlation factors for each variable were all less than 0.37. Classification of fovea contour also had poor correlation with BCVA. Conclusion: OCT 3 findings are not predictive of BCVA following macular hole surgery. Physiologic factors not demonstrable by OCT analysis significantly contribute to overall visual acuity.
