Summary
Subretinal membranes (SRMs) are a key factor in proliferative vitreoretinopathy (PVR) surgery. Identifying and removing SRMs can improve retinal reattachment rates, though visual outcomes require further study.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Subretinal membranes (SRMs) are a significant but often overlooked component of proliferative vitreoretinopathy (PVR).
- Their presence can complicate surgical outcomes in PVR cases.
Purpose of the Study:
- To investigate the incidence and impact of Subretinal Membranes (SRMs) in eyes undergoing vitreoretinal surgery for proliferative vitreoretinopathy (PVR).
- To evaluate the outcomes of SRMs removal on retinal reattachment and visual acuity.
Main Methods:
- Retrospective analysis of 153 consecutive eyes with PVR undergoing vitreoretinal surgery.
- Documentation of SRM presence, necessity for removal, surgical complications, and post-operative outcomes including retinal reattachment and visual acuity.
Main Results:
- SRMs were identified in 47% of PVR cases.
- In 28% of eyes with SRMs, removal was necessary due to prevention of retinal reattachment, with associated intraoperative complications.
- Following removal, 65% of retinas achieved reattachment, but only 20% had visual acuity of 5/200 or better.
Conclusions:
- Recognizing and addressing SRMs is crucial for maximizing anatomical success in PVR surgery.
- While SRMs removal can aid retinal reattachment, its long-term effect on visual function remains uncertain and warrants further investigation.
