NCT04997876

Brief Summary

Several optical coherence tomography (OCT) biomarkers with potential to influence postsurgical outcomes after vitrectomy with membrane peeling for idiopathic epiretinal membranes (iERM) have been described in single predictor analyses in the past. Aim of the study is to assess the reliability of diagnosis of OCT biomarkers and to calculate their impact on postsurgical visual acuity in a multiple regression analysis.

Outcome Measures

Primary Outcomes (1)

  • reliability of diagnosing OCT biomarkers

    The presence (yes/no) of following OCT biomarkers are diagnosed from preoperative OCTs: EIFL, DRIL, intraretinal cystoid changes, alterations of the ellipsoid zone, cotton ball sign, HR-foci, EMM-rips, and retinal contraction. Intra- and interobserver reliability is assessed from 2 different readers, and reliability of OCT biomarkers will be calculated with the Kuder Richardson 20 test, due to the dichtomic nature of outcomes.

    1 week

Secondary Outcomes (2)

    3 months

  • central macular thickness

    5 minutes

Sampling MethodProbability Sample
Study Population

Patients with iERM sheduled for vitrectomy with membrane peeling.

You may qualify if:

  • a) presence of an iERM,
  • b) indication for membrane peeling, defined as significant loss of visual acuity and/or metamorphopsia due to the ERM,
  • c) pseudophakia at the final visit at 3 months after surgery, and
  • d) written informed consent for study participation.

You may not qualify if:

  • macular edema caused by conditions other than ERM were excluded from the study.
