Summary
Idiopathic epiretinal membrane surgery improves vision. Higher baseline parafoveal vessel density predicts better visual acuity and fixation stability outcomes post-surgery.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Surgical Outcomes
Background:
- Idiopathic epiretinal membrane (iERM) affects the macula, potentially impacting visual function.
- Understanding visual recovery and its predictors after iERM surgery is crucial for patient management.
Purpose of the Study:
- To investigate visual function changes after iERM surgery.
- To identify predictors of postoperative visual outcomes in iERM patients.
Main Methods:
- Retrospective study of 37 eyes with iERM.
- Macular structure assessed by OCT and OCTA.
- Visual function evaluated by BCVA and microperimetry at baseline, 3, and 6 months postoperatively.
Main Results:
- Significant improvements in BCVA, retinal sensitivity, and fixation stability observed post-surgery.
- Parafoveal vessel density of the deep capillary plexus (PFVD of DCP) at baseline predicted better BCVA and fixation stability.
- Central retinal thickness decreased, while macular integrity showed no significant change.
Conclusions:
- iERM surgery leads to significant visual function improvements, with BCVA recovery preceding microperimetry gains.
- Baseline PFVD of the DCP is a key prognostic factor for visual recovery post-iERM surgery.
