Pneumatic retinopexy using only air achieved high retinal reattachment rates (86.7%) and good visual outcomes. This method may reduce complications like proliferative vitreoretinopathy (PVR) and premacular membranes (PMM).

Area of Science:

  • Ophthalmology
  • Retinal Surgery

Background:

  • Rhegmatogenous retinal detachment (RRD) is a serious condition requiring timely intervention.
  • Minimizing vitreous disturbance is crucial to prevent complications like proliferative vitreoretinopathy (PVR).

Purpose of the Study:

  • To evaluate the efficacy and safety of pneumatic retinopexy using only air for RRD.
  • To assess the incidence of PVR and premacular membranes (PMM) post-procedure.

Main Methods:

  • Pneumatic retinopexy with air was performed on 45 eyes with superior breaks and no preoperative vitreous hemorrhage or PVR.
  • Retinal cryopexy or laser treatment was used in conjunction.
  • Intravitreal injection of 0.8 cc filtered air was administered.

Main Results:

  • Successful reattachment was achieved in 39 eyes (86.7%).
  • Secondary scleral buckle surgery was successful in the remaining 6 eyes.
  • Visual acuity remained the same or improved in 97.8% of eyes after an average follow-up of 17.1 months.

Conclusions:

  • Pneumatic retinopexy with air offers a high reattachment rate and favorable visual outcomes.
  • The technique appears to have a low incidence of PVR, PMM, and new or missed retinal breaks.
  • The short-acting, nonexpansile nature of air may contribute to these positive results.
