Abstract/OtherAbstract:
BACKGROUND: to evaluate the correlation between the extent of the inner/outer segment (IS/OS) defect preoperatively and improvement in postoperative best-corrected visual acuity (BCVA) associated with IS/OS line restoration.
METHODS: forty-six eyes (46 patients) with successfully operated idiopathic full-thickness macular holes were studied using Stratus OCT3 with a mean follow-up of 34.7 months (range 24-60 months). The preoperative extent of the IS/OS junction defect, macular hole base diameter (MHBD) and BCVA were studied before surgery. The degree of IS/OS line restoration, macular thickness and BCVA were measured after treatment.
RESULTS: the mean preoperative MHBD and IS/OS defect size were 783 and 1,973 μm, respectively. Postoperative continuity of the IS/OS junction was observed in 11 of 46 cases 12 months after treatment. In the remaining 35 patients, the IS/OS line was interrupted at 12 months of follow-up. The size of the preoperative IS/OS defect line was negatively correlated with the size of the postoperative IS/OS line and BCVA at 6 months and 12 months only (p < 0.0001). In all 46 eyes, the mean BCVA before and 12 months after treatment was 10 and 36.7 letters, respectively. BCVA remained almost unchanged after the first postoperative year of observation.
CONCLUSIONS: the degree of reorganization of the photoreceptor layer after successful macular hole closure varies and is mostly related to the preoperative extent of the IS/OS defect line and the MHBD. A small-sized IS/OS preoperative defect favors improvement and restoration of the IS/OS line after treatment. The IS/OS junction line and BCVA are mostly restored during the first 12 months after treatment.
