Outcomes after Failed Pneumatic Retinopexy for Retinal Detachment

Area of Science:

• Ophthalmology
• Retinal Surgery
• Surgical Outcomes

Background:

• Pneumatic retinopexy (PR) is a common primary treatment for retinal detachment (RD).
• Failure of primary PR necessitates secondary surgical intervention to restore retinal anatomy and visual function.
• Understanding the outcomes of different secondary procedures is crucial for managing failed PR cases.

Purpose of the Study:

• To evaluate the visual and anatomic outcomes of secondary surgical procedures following primary pneumatic retinopexy (PR) failure in patients with retinal detachment (RD).
• To compare the efficacy of repeat PR, pars plana vitrectomy (PPV), and combined scleral buckle (SB) plus PPV (SB+PPV) as secondary treatments for failed PR.

Main Methods:

• Retrospective, single-center case series of patients with RD whose primary PR failed.
• Evaluation of anatomic reattachment and visual acuity (VA) at one year post-secondary intervention.
• Comparison of outcomes between repeat PR, PPV, and SB+PPV groups.

Main Results:

• The study included 73 eyes with failed primary PR; 75% achieved anatomic success with a single secondary surgery, reaching 100% by one year.
• No statistically significant difference in success rates was observed between repeat PR (63%), PPV (76%), and SB+PPV (88%).
• Visual acuity improvement at one year was similar across all groups, though better in eyes without macular involvement.

Conclusions:

• Secondary procedures for failed PR, including repeat PR, PPV, and SB+PPV, yield lower success rates than primary use, suggesting these RDs are more complex.
• While SB+PPV trended towards higher anatomic success, differences were not statistically significant and did not impact one-year visual acuity gains.
• The choice of secondary procedure depends on patient factors, surgeon preference, and patient preference, emphasizing a tailored approach to managing failed PR.
