From Observation to Surgery: A Review of Literature and an Updated Algorithm for Acquired Retinoschisis and Schisis-Detachment

This review critically synthesizes current evidence regarding the natural history, advanced diagnostic imaging, and therapeutic interventions for acquired retinoschisis and retinoschisis-associated retinal detachment. A systematic search of PubMed and Embase databases was conducted for literature published up to 2026, focusing on comparative outcomes of scleral buckling versus pars plana vitrectomy and novel imaging modalities. The advent of ultra-widefield optical coherence tomography has shifted the diagnostic paradigm, enabling the precise identification of outer layer breaks as the primary biomarkers for progression. While observation is mandated for asymptomatic, non-progressive cases, the choice between buckling and vitrectomy for active detachments is often driven by surgeon preference rather than anatomical necessity. We propose an updated decision-making algorithm that integrates lens status, break localization, and vitreous findings to guide the surgical approach. Moving beyond a "one-size-fits-all" strategy, this review advocates for a personalized management plan that balances anatomical success with long-term quality of life.
