Purpose: To evaluate the capacity of spectral domain optical coherence tomography macular findings to predict best-corrected visual acuity (BCVA) outcomes after treatment for symptomatic vitreomacular traction.

Methods: This consecutive, retrospective study included 24 patients (29 eyes) who experienced vitreomacular traction release with pneumatic vitreolysis (n = 9), intravitreal ocriplasmin (n = 6), or pars plana vitrectomy (n = 14). Preoperative and postoperative spectral domain optical coherence tomography images were used to determine the cone outer segment tips (COST) line, inner segment/outer segment line, and other frequently used features. Correlations between optical coherence tomography findings and BCVA were determined using regression analyses.

Results: Postoperative BCVA was correlated with length of the COST line and inner segment/outer segment line defects at 1, 3, 6, and 12 months postoperatively (P < 0.05) by simple linear regression analysis. However, multivariable regression analysis showed that only length of the COST line defect was significantly correlated with BCVA preoperatively and postoperatively (P < 0.05). Postoperative BCVA improvement at 12 months was significantly correlated with preoperative length of the COST line defect (P < 0.01).

Conclusion: Recovery of the COST line and inner segment/outer segment line defects as observed by spectral domain optical coherence tomography is positively correlated with visual acuity improvement after successful vitreomacular traction treatment. Best-corrected visual acuity improvement may be predicted using the length of the preoperative COST line defect.

This retrospective study evaluated the correlations of spectral domain optical coherence tomography findings and visual outcome after treatments for vitreomacular traction and found that length of the cone outer segment tips line defect was the most correlative factor among all optical coherence tomography findings for the prognosis of vitreomacular traction treatments.
