According to a study published in JAMA Ophthalmology, Retinal displacement following rhegmatogenous retinal detachment repair may have consequences for visual function. It is important to know whether the surgical technique is associated with the risk of displacement. A study was conducted to compare retinal displacement following rhegmatogenous retinal detachment repair with pneumatic retinopexy (PR) vs pars plana vitrectomy (PPV). Fundus autofluorescence images were assessed by graders masked to the surgical technique.

Retinal displacement and low-integrity retinal reattachment appear to occur more frequently and are more severe with PPV vs PR. This study suggests a difference in anatomic integrity of retinal reattachment achieved with different surgical procedures, by comparing retinal displacement assessed by retinal vessel printing on fundus autofluorescence imaging. Recognition of the importance of retinal displacement and integrity of retinal reattachment (high-integrity vs low-integrity retinal reattachment) may lead to further refinements in vitreoretinal surgery techniques for primary rhegmatogenous retinal detachment repair and potentially improved functional outcomes for patients.

Question: Is there a difference in retinal displacement following rhegmatogenous retinal detachment repair with pneumatic retinopexy vs pars plana vitrectomy?

Findings: This case series including 238 eyes found that retinal displacement detected by retinal vessel printings on fundus autofluorescence imaging developed in 7.0% of pneumatic retinopexy–treated eyes vs 44.4% of pars plana vitrectomy–treated eyes.

Meaning: These results suggest that retinal displacement may be more severe and occurs more frequently with pars plana vitrectomy vs pneumatic retinopexy.
