Pneumatic Retinopexy for the Management of Rhegmatogenous Retinal Detachment.

Area of Science:

• Ophthalmology
• Retinal Surgery
• Minimally Invasive Procedures

Background:

• Rhegmatogenous retinal detachment (RRD) requires surgical intervention.
• Pars plana vitrectomy (PPV) is a common but invasive RRD repair method.
• Pneumatic retinopexy (PnR) is a less invasive, office-based alternative for select RRD cases.

Purpose of the Study:

• To compare the functional outcomes and complication rates of Pneumatic Retinopexy (PnR) versus Pars Plana Vitrectomy (PPV) for RRD repair.
• To elucidate the reasons behind the observed differences in visual acuity and cataract progression between PnR and PPV.
• To provide evidence-based insights for selecting the optimal surgical technique for RRD management.

Main Methods:

• Literature search of PubMed, Cochrane Library, and Google Scholar for comparative studies of PnR and PPV.
• Inclusion of systematic reviews, meta-analyses, and randomized controlled trials (RCTs) published in English within the last 10 years.
• Narrative review synthesizing findings on visual outcomes, metamorphopsia, and cataract development.

Main Results:

• PnR demonstrates superior best-corrected visual acuity (BCVA) and reduced metamorphopsia compared to PPV.
• PnR is associated with significantly lower rates of cataract progression than PPV.
• While primary PnR reattachment rates are lower, final anatomical success rates are comparable to PPV.
• Reduced retinal displacement and preserved photoreceptor integrity contribute to better visual outcomes with PnR.

Conclusions:

• PnR provides superior functional visual outcomes and a lower risk of cataract progression compared to PPV for RRD repair.
• The choice between PnR and PPV should consider not only anatomical success but also the quality of vision.
• Further large-scale RCTs with extended follow-up are warranted to confirm these findings and focus on visual quality metrics.
