Management of limited macula-sparing rhegmatogenous retinal detachment: observation, demarcation laser photocoagulation, or surgery—a clinical review

Background Management of limited macula-sparing rhegmatogenous retinal detachment (RRD) remains uncertain. Some eyes remain stable under observation, while others are treated with demarcation laser photocoagulation (DLP) or surgery. We reviewed the available evidence for these management options and integrated it into a practical framework for clinical decision-making based on the presenting phenotype and the limitations of the available evidence. Main body We searched PubMed/MEDLINE, Embase, Scopus, and Web of Science from inception to July 30, 2026, for clinical reports on observation, natural history, DLP, or delayed surgery in limited macula-sparing RRD. The literature was synthesized narratively because definitions, selection criteria, and outcomes varied widely. Natural-history studies suggest that some asymptomatic, peripheral, chronic-appearing detachments, especially inferior or temporal lesions related to small atrophic holes and limited traction, may remain stable for years. However, these cohorts were small and highly selected, and progression, including macular involvement, still occurred. Many eyes remained contained after DLP, although repeat laser and rescue surgery were not uncommon. Definitions of success differed, particularly in whether additional laser was allowed. Outcomes were less predictable in symptomatic, superior, tractional, bullous, more posterior, or more extensive detachments. No study directly compared all three management strategies. Peripheral visual-field outcomes were also rarely assessed, so stable central acuity does not necessarily mean that peripheral function was preserved. In practice, the choice among these approaches depends on symptoms, location, break type, vitreoretinal traction, chronicity, posterior extent, whether a complete laser barricade is feasible, as well as the reliability of follow-up. Conclusions Observation may be reasonable for carefully selected stable-appearing detachments. DLP may be considered as an intermediate containment strategy when observation seems too uncertain but surgery is not clearly required. Operative repair remains the preferred approach for progressive, macula-threatening, markedly tractional, bullous, or otherwise high-risk RRD.
