Visual Outcomes in Macula-Involving Retinal Detachments Based on Time to Surgical Repair.

BACKGROUND AND OBJECTIVE: To examine the relationship between duration of macular detachment and postoperative visual acuity in macula-involving rhegmatogenous retinal detachments. PATIENTS AND METHODS: Retrospective review of patients who underwent surgical repair of macula-involving rhegmatogenous retinal detachments was conducted with Institutional Review Board approval. Primary outcome measure was postoperative best-corrected visual acuity (BCVA) as dependent on duration of macular detachment. RESULTS: In eyes with duration of macular detachment less than or equal to 7 days, postoperative BCVA increased by 0.017 logarithm of the minimum angle of resolution (logMAR) units (P = .001), and the odds of achieving logMAR 0 decreased by a factor of 0.43 (95% CI, 0.21 to 0.87; P = .02) with each additional day of detachment. Eyes repaired within 3 days of macular detachment were more likely to have postoperative BCVA of logMAR 0 than eyes repaired 4 to 7 days after macular detachment (odds ratio, 2.32; 95% CI, 1.15 to 4.70; P = .02). CONCLUSION: Increased duration of macular detachment is associated with progressive decline in postoperative visual acuity. [Ophthalmic Surg Lasers Imaging Retina 2022;53:439-444.].

The Last 200 Surgeon-Loaded Descemet Membrane Endothelial Keratoplasty Tissue Versus the First 200 Preloaded Descemet Membrane Endothelial Keratoplasty Tissue.

PURPOSE: The purpose of this study was to compare the clinical outcomes from using eye bank-prepared, endothelium-out preloaded Descemet membrane endothelial keratoplasty (DMEK) tissue with those obtained with endothelium-out surgeon-loaded DMEK tissue using the same surgical technique at 1 site. METHODS: This study retrospectively reviewed 400 consecutive cases of DMEK from March 2016 to April 2018. The last 200 cases using surgeon-loaded tissue were compared with the first 200 cases using preloaded tissue. Statistical analysis was performed using the Wilcoxon signed-rank test, binomial logistic regression, Kruskal-Wallis 1-way analysis of variance, Student t test, or Pearson χ tests. RESULTS: Comparing surgeon-loaded versus preloaded DMEK tissue, respectively, no statistical difference was found in the mean 6-month postoperative values for endothelial cell loss (32.9% ± 18.5% vs. 29.9% ± 16.4%, P = 0.31), best corrected visual acuity (20/26 vs. 20/25, P = 0.54), or change in central corneal thickness (-14.4% ± 8.9% vs. -15.6% ± 11.7%, P = 0.43). The mean 1-year endothelial cell loss was also not significantly different (37.6% ± 17.2% vs. 33.2% ± 14.8%, P = 0.07). Overall, the rebubble rate for surgeon-loaded tissue was 17.5% and 12.5% for preloaded tissue, a statistically nonsignificant difference. Operative outcomes for mean tissue scroll tightness (1-4) and tissue unscroll time (minutes) for surgeon-loaded and preloaded tissue were similar between groups (2.4 vs. 2.2, P = 0.12 and 3.5 vs. 3.3 minutes, P = 0.50). CONCLUSIONS: Tissue that is trephinated, stained, and loaded into an injector by the eye bank and then shipped to the surgeon had no difference in clinical outcomes compared with tissue where the surgeon performs these steps. The safety and speed of using preloaded tissue should be considered by DMEK surgeons.
