Large macular hole and autologous retinal transplantation: a systematic review and meta-analysis

Abstract

Introduction: Macular holes are breaks in the retinal tissue at the center of the macula, affecting central vision. The standard treatment involves vitrectomy with membrane peeling and gas tamponade. However, for larger or chronic holes, alternative techniques like autologous retinal graft have emerged. This meta-analysis evaluates the efficacy and safety of retinal transplantation in managing large macular holes.

Methods: We conducted a systematic review and meta-analysis following PRISMA guidelines. The study was prospectively registered in PROSPERO (CRD42024504801). We searched PubMed, Web of Science, Cochrane, and Embase databases for observational studies including individuals with large macular holes with or without retinal detachments and retinal transplantation as the main therapy. We used a random-effects model to compute the mean difference with 95% confidence intervals and performed statistical analysis using R software.

Results: We conducted a comprehensive analysis of 19 studies involving 322 patients diagnosed with various types of macular holes (MHs). These included cohorts with refractory MH, high myopia associated with MH, primary MH, and MH with retinal detachment (RD). The findings were promising, revealing an overall closure rate of 94% of cases (95% CI 88-98, I2 = 20%). Moreover, there was a significant improvement in postoperative visual acuity across all subgroups, averaging 0.45 (95% CI 0.33-0.58 ; I2 = 72%; p < 0.01) overall. However, complications occurred with an overall incidence rate of 15% (95% CI 7-25; I2 = 59%).

Conclusion: ART for large MH shows promising results, including significant improvements in visual acuity and a high rate of MH closure with low complication risks overall and for subgroups.
