Purpose: To analyze the recovery of retinal lines using swept-source optical coherence tomography after inverted internal limiting membrane flap technique to treat full-thickness macular hole, and the relationship between best-corrected visual acuity and retinal line repair.

Methods: Thirty-eight eyes were evaluated for recovery of the external limiting membrane, photoreceptor inner segment/outer segment junction line, and cone outer segment tips (COST) line. Correlation between the recovery of retinal lines and best-corrected visual acuity improvement was analyzed 6 months after surgery.

Results: The closure rate of full-thickness macular hole was 97%. The best recovery rates were associated with external limiting membrane line recovery (25 eyes, 65.8%), followed by inner segment/outer segment line recovery (22 eyes, 57.9%), and less frequently, COST line recovery (9 eyes, 23.7%); moreover, recovery of the COST line was apparent only in eyes with recovered external limiting membrane and inner segment/outer segment lines. Mean postoperative visual acuity in the COST line recovery group (COST+) was 20/42 (0.48, 0.33 logarithm of the minimum angle of resolution), compared with 20/95 (0.21, 0.68 logarithm of the minimum angle of resolution) without COST line recovery (COST−). Final visual acuity was significantly better in the COST+ group compared with the COST− group (P = 0.002).

Conclusion: Cone outer segment tips line recovery is correlated with best-corrected visual acuity improvement for eyes treated with inverted internal limiting membrane flap technique for full-thickness macular hole.

To analyze the recovery of retinal lines using swept-source optical coherence tomography, as well as changes in best-corrected visual acuity, after inverted internal limiting membrane flap technique for full-thickness macular hole. Recovery of the cone outer segment tips line was associated with significant best-corrected visual acuity improvement.
